However, secondary liver involvement is fairly common and is usually associated with lymph node disease. It can cause abdominal pain, diarrhea, gastrointestinal tract bleeding, and swollen stomach. Extranodal lymphoma occurs in about 40% of patients and has been described in virtually every organ and tissue. B-cell lymphomas are far more common than T-cell lymphomas. Although bile duct obstruction may occur, moderate-to-severe dilatation of the main pancreatic duct is uncommon . Lymph is colorless because it lacks red blood cells; instead, it contains lymphocytes. Our surgeons have expertise in performing lymph node biopsies that ensure adequate tissue is gathered to make a precise diagnosis. The patterns of involvement include a circumscribed mass and diffuse glandular enlargement mimicking acute pancreatitis. Stomach cancer risk after treatment for Hodgkin lymphoma.

Lymph Node Biopsy: A procedure in which a portion of or an entire lymph node is surgically removed so it can be examined under a microscope to look for the presence of lymphoma cells. Liu, “CT diagnosis of 52 patients with lymphoma in abdominal lymph nodes,”, U. Metser, O. Goor, H. Lerman, E. Naparstek, and E. Even-Sapir, “PET-CT of extranodal lymphoma,”, A. Guermazi, P. Brice, E. De Kerviler et al., “Extranodal Hodgkin disease: spectrum of disease,”, R. E. Dorfman, M. B. Alpern, B. H. Gross, and M. A. Sandler, “Upper abdominal lymph nodes: criteria for normal size determined with CT,”, P. A. The purpose of this review is to discuss and illustrate the spectrum of appearances of nodal and extranodal lymphomas, including AIDS-related lymphomas, in the abdominopelvic region using a multimodality approach, especially cross-sectional imaging techniques. CT of the abdomen demonstrates lymph nodes involving mesenteric vessels (sandwich sign) anterior to aorta and inferior to vena cava in a patient with lymphoma (arrows). The cecum and rectum are most commonly involved . Diffuse lymphomatous infiltration of the mesentery produces a stellate appearance of the mesentery and causes fixation of the small bowel loops . It is usually diffuse, with discrete nodular lesions being present in only 10% of cases. If nodes have low-attenuation centers, mycobacterial infection, rather than lymphoma, is likely . A grossly enlarged psoas muscle may represent a primary manifestation of ARL . The confluence of enlarged LN of HD is seldom seen (16.7%), which mainly occurs in multiple-nodular type (60%). When under certain circumstances, the lymphocytes grow and multiply abnormally, it leads to a condition called as lymphoma, which is a most common type of cancer. Recent studies indicate that PET/CT is superior to CT in detecting extranodal disease in the abdomen, especially in the spleen and liver [2, 4, 7, 8]. In patients with known disease, the goals of imaging are staging, evaluation of response to therapy, and identification of new or recurrent disease or of complications of therapy. Lymphocytes are made in bone marrow, and can develop into either B-cells or T-cells, Lymph results from filtration of blood as it travels to and from tissues. Secondary involvement of the testis by NHL is more common than primary extranodal disease . The CT manifestations of nodal disease before and after radiochemotherapy are different, including changes in internal nodal characteristics. Some risk factors are more important than others. Lymphoma of Stomach diagnosis is generally performed by obtaining biopsy samples from the stomach/affected region and examining them under a microscope to detect the cancerous cells. They help your doctor see the organs, blood vessels, and bones in your abdomen. The patterns of gastric involvement include polypoidal mass, diffuse or focal infiltration, ulcerative lesion, or mucosal nodularity . Lymphoma of the stomach. Diffuse organ involvement is also possible, most commonly affecting the liver and spleen with corresponding organomegaly and variable CT attenuation . Because the pancreas has no definable capsule, it may be difficult to distinguish adjacent LN disease from intrinsic pancreatic infiltration . CT usually shows a huge round mass or a lobular homogeneous density mass with uniform enhancement . Due to this, individuals are more vulnerable to infections; there is an increased risk of developing serious complications from such infections, Occasionally, the tumor can transform into a more aggressive form or subtype of lymphoma, Side effects such as dizziness, vomiting, appetite loss, mouth ulcers, and hair loss, By damaging healthy cells, the individual is more open or vulnerable to secondary infections, The treatment can also cause infertility in men and women. This computed tomography scan is from a 46-year patient with Hodgkin lymphoma at the level of the neck. Appendiceal lymphoma may present clinically as acute appendicitis . The pancreas is involved in about 30% of cases of NHL, usually from contiguous nodal infiltration [2, 12]. Despite peripelvic lymphoma encasing renal hilar structures, the vessels often remain patent, and there is often minimal hydronephrosis (Figure 30) which helps to differentiate peripelvic lymphoma from transitional cell carcinoma or metastases . The patterns of testicular involvement include focal masses and diffuse infiltration with or without testicular enlargement [2, 14]. Bone scan: In a bone scan, a radioactive isotope called technetium-99m is injected into a vein and Gerber, B. C. (1964). Splenic involvement is typically diffuse, and only a small minority of cases manifest nodules larger than 1 cm in diameter. Bone marro… MRI is used in local staging of rectal cancers. This could be from lymph nodes or organs such as the spleen or liver enlarging, but it can also be caused by the build-up of large amounts of fluid. 2. ARL may affect any abdominal organ, most commonly LN, the GI tract, liver, kidney, adrenal gland, omentum, and abdominal wall. Primary lymphoma of the appendix is also very rare, with only a few case reports in the literature, although it is more common to see cecal lymphoma extending to the base of the appendix [10, 11]. Ansari, M., Nasrolahi, H., Kani, A. Whole body CT-PET scans to determine how far the lymphoma has spread, by checking the size and metabolic rate (a reflection of uncontrolled growth) of lymph nodes, throughout the body. A. Magnetic resonance imaging (MRI). Nevertheless, this procedure is not very much used, Bone marrow aspiration and biopsy is performed and sent to a laboratory for a pathological examination, to determine if the bone marrow is involved. Your doctor will want to get a complete medical history, including information about your symptoms, possible risk factors, and other medical conditions. The kidney is the most commonly involved part of the GU tract [2, 13]. Renal involvement is extremely rare, with HD being rather perirenal and with radiologic appearance often consisting of invasion of the perirenal space by HD without renal parenchymal involvement . The test is ultrasensitive and detects extremely low amounts of biomarkers remaining in blood, which can be missed by cytogenetic methods, such as FISH, karyotype, or flow cytometry. The images can then be examined on a computer monitor or printed. The patterns of renal involvement, in descending order of frequency, include multiple circumscribed masses (Figure 27), direct infiltration from adjacent nodes, a solitary mass, an isolated perinephric mass (Figure 28), and diffuse infiltration (Figure 29) [2, 13]. Springer-Verlag. Primary NHL, Burkitt lymphoma, MALT-type lymphoma, and, rarely, HD have been described involving the small intestine . Living with Lymphoma: A Patient's Guide. BMC cancer, 13(1), 1. Bilateral adrenal involvement occurs in approximately 50% of these cases (Figure 31). The patterns of small bowel involvement include solitary or multiple nodules, circumferential wall thickening (Figure 21) with or without aneurysmal dilatation, and direct extension from mesenteric nodes [2, 10]. 2013, Article ID 483069, 11 pages, 2013. https://doi.org/10.5402/2013/483069, 1Hospital das Clínicas da Universidade Federal de Pernambuco, UFPE, Escola Paulista de Medicina, UNIFESP, Avenida Professor Moraes Rego, s/n, Cidade Universitária, 50670-420 Recife, PE, Brazil. Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis. General information on lymphoma and lymphocytes: No specific risk factors have been identified for Lymphoma of Stomach. Journal of Clinical Oncology, 31(27), 3369-3377. Extranodal lymphoma in the GI tract occurs in 10–30% of all patients with NHL . It is involved in 20–40% of patients with lymphoma. A. Esplin, A. M. Levine, and P. W. Ralls, “AIDS-related non-Hodgkin's lymphoma: abdominal CT findings in 112 patients,”, R. R. Townsend, “CT of AIDS-related lymphoma,”, E. J. Balthazar, M. Noordhoorn, A. J. Megibow, and R. B. Gordon, “CT of small-bowel lymphoma in immunocompetent patients and patients with AIDS: comparison of findings,”. However, the fusion of enlarged LN is common (60%) in NHL, showing vessel-imbedded signs, intestinal-imbedded signs, and cobblestone signs . (2013). Focal hepatic masses of lymphoma are much more common in AIDS patients than in the non-AIDS population. Many clinical conditions may have similar signs and symptoms. Also, primary lymphomas have better prognoses than secondary or recurrent lymphomas. 6 Contrast Parameters Parameters ... Use 100 cc if combined with abdomen CT Injection Rate 4-5cc/sec The patterns of bladder involvement include circumscribed solitary or multiple masses and diffuse infiltration . In higher-stage tumors, such as tumors with metastasis, the prognosis is poor, Overall health of the individual: Individuals with overall excellent health have better prognosis compared with those with poor health, Age of the individual: Older individuals generally have poorer prognosis than younger individuals, The size of the tumor: Individuals with small-sized tumors fare better than those with large-sized tumors, Individuals with bulky disease have a poorer prognosis, Involvement of vital organs may complicate the condition, The surgical respectability of the tumor (meaning, if the tumor can be removed completely) - it is a rare option, Whether the tumor is occurring for the first time, or is a recurrent tumor. Friedman, M., Lee, K. R., Kim, H. J., Lee, I. S., & Kozukue, N. (2005). Though it may be part of a systemic lymphoma, single onset of nodal lymphoma is not rare. This image reveals diffuse renal lymphoma, in which diffuse, small nodules are scattered throughout both kidneys. 7A, 7B) and can be difficult to detect with conventional contrast-enhanced CT. The most common radiologic patterns of involvement are illustrated. Lymphomatous involvement of the biliary tree is rare. After putting together clinical findings, special studies on tissues (if needed) and with microscope findings, the pathologist arrives at a definitive diagnosis. In general, the prognosis depends upon a set of several factors, which include: Stage of tumor: With lower-stage tumors, when the tumor is confined to site of origin, the prognosis is usually excellent with appropriate therapy. Also the extent of extranodal involvement must be evaluated because it is considered prognostic . Bone marrow aspiration and biopsy. This can also help determine, if the cancer has spread to other organ systems, Brain MRIs are used if neurological symptoms are present, which can help determine if the cancer has spread to the brain, or to tissues that cover the brain, Exploratory laparoscopy (diagnostic laparoscopy) may be required, if gastrointestinal symptoms are present. Flow cytometry measures the number and percentage of cells in a blood sample, and cell characteristics such as size, shape, and the presence of biomarkers on the cell surface. A risk factor increases ones chances of getting a condition compared to an individual without the risk factors. It is always important to discuss the effect of risk factors with your healthcare provider. Nevertheless, how this occurs and the factors that cause it remain under investigation. Profession involving radiation exposure, which may include nuclear plant workers, pilots, astronauts, etc. In combination with other treatment measures, these can help combat the symptoms of immunodeficiency, Undertaking treatment of underlying conditions/disorders, as warranted, If Gastric Lymphoma is not fully responsive to treatment, or if the chance of recurrence is high, then bone marrow transplantation or stem cell transplantation can be considered, In order to prevent infections because the immune system is weakened by the lymphoma or by its treatment, the patient is kept in an isolated ward and treated with appropriate antibiotics, Nowadays targeted therapies are being developed that can selectively kill the cancer cells. An MRI uses magnetic fields, not x-rays, to produce detailed images of the body. Hepatomegaly is common in patients with AIDS, and occasionally a large liver may harbor lymphoma without focal lesions evident on CT [16, 17]. Increase in heterogeneous or rim enhancement of LN due to intranodular necrosis after treatment and calcifications of lesions may occur (Figure 7) . Lymphomas frequently involve nodal and extranodal structures in the abdomen and pelvis [2, 3]. Lymphoma is the most common testicular tumor in older men; bilateral involvement occurs in 38% of cases. For initial staging of splenic involvement in malignant lymphoma, the sensitivity and specificity of PET/CT can reach 100% and 95%. The ureter is often affected by involved retroperitoneal nodes, but primary involvement of the ureter by lymphoma is rare. Multiple sites are rarely involved in disseminated HD . Long-term follow-up of gastric lymphoma after stomach conserving treatment. Also, not having a risk factor does not mean that an individual will not get the condition. The patterns of involvement include diffuse infiltration, with or without splenomegaly, and focal nodules . In patients without known disease, imaging permits a provisional diagnosis. Focal splenic lesions are also seen more commonly in ARL than in lymphoma without AIDS. Adverts are the main source of Revenue for DoveMed. CT scans can show up swollen (enlarged) lymph nodes in your body. Your doctor may recommend a lymph node biopsy procedure to remove all or part of a lymph node for laboratory testing. Springer, Berlin, Heidelberg. Lymphoplasmacytic lymphoma shows evidence of lymphadenopathy, and hepatosplenomegaly. They fight viruses and cancerous cells, B-lymphocytes or B cells: They produce antibodies that are bodily defense proteins, which target foreign invaders outside the cells (humoral immunity). Please remove adblock to help us create the best medical content found on the Internet. Certain subtypes of lymphoma, such as extranodal marginal zone lymphoma and T-cell cutaneous lymphoma , exhibit variable FDG uptake (Fig. CT scans are used to look at the head and neck, spine, chest, abdomen (stomach) and pelvis. The patterns of involvement of the bile ducts include a biliary stricture mimicking cholangiocarcinoma and a focal mass . Splenic involvement is found at initial presentation of lymphoma in 30–40% of patients with HD and in 10–40% of patients with NHL . the overall health condition of the individual, which could range from being fully active (low risk) to being completely disabled (very high risk), Individual, who have already suffered from lymphoma, or other types of blood cancers, may have a relapse or a recurrence, Presence of an immunodeficiency syndrome, like AIDS, is a high risk factor, Those infected with Epstein-Barr virus are also prone to this lymphoma type, Change of regulatory elements of certain cancer-causing genes called as oncogenes, which can lead to increased production of their mRNA (overexpression), thus increasing their protein levels, Exchange of protein coding regions of gene, giving rise to new proteins that can stimulate the inappropriate growth of cells, Unintentional weight loss; changes in appetite, High temperatures and excessive night sweats (may be recurrent), A thorough physical examination and a complete medical history, which is very important, Complete blood cell count (CBC) blood test, Absolute lymphocyte count on peripheral blood, A biopsy of the tumor is performed and sent to a laboratory for a pathological examination. CT scans of the chest, abdomen, and pelvis can help find cancer that has spread to the lungs, lymph nodes, spleen, and liver. However, lymphoma could be in neck, chest, etc and be undetected. NHL has a wide distribution including all sites of abdominal LN (Figure 6), and the mesentery is frequently involved (45%). The patterns of involvement of the gallbladder include an intraluminal polypoidal mass, a large mass replacing the gallbladder, and diffuse mural thickening . Nodal disease can be solitary or more commonly multiple . Best Practice & Research Clinical Gastroenterology, 24(1), 71-77. Regular medical screening at periodic intervals with blood tests, scans, and physical examinations, are mandatory. Intrinsic involvement of genitourinary (GU) organ systems at presentation is rare . Adler, E. M. (2005). CT of the lungs or abdomen can also be diagnostic for infection, which is particularly relevant to immunocompromised patients. Multiple-nodular type of lymphoma, the most frequently seen, can be characterized by enlarged LN with regional distribution (Figures 2 and 3). The malignant lymphomas, Hodgkin disease (HD) and non-Hodgkin lymphoma (NHL), comprise approximately 5% to 6% of all malignancies . The purpose of this review is to discuss and illustrate the spectrum of appearances of nodal and extranodal lymphomas, including AIDS-related lymphomas, in the abdominopelvic region using a multimodality approach, especially cross-sectional imaging techniques. There are other tests and procedures that could help in the diagnosis and these include: Note: Differential diagnoses, to eliminate other tumor types are often considered, before arriving at a definitive diagnosis. If lymphoma or another serious condition is suspected, your doctor may order imaging tests like X-rays or a CT scan. According to the American College of Radiology, possible diagnoses include: infections such as appendicitis, pyelonephritis or infected fluid collections, also known as abscesses. PCR allows a more sensitive follow-up of patients in remission and can help determine whether additional treatment is necessary, Involvement of local and distant organs: It can lead to systemic or disseminated disease in some cases, Loss of function of the organ/area to which cancer has spread due to systemic involvement, If the abdomen is affected, it can cause intestinal obstruction that results in urine outflow obstruction and kidney damage, Weakened immune system (or immunosuppression) can be a complication, which can become more severe during treatment. CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity than conventional x-ray exams. In decreasing order of frequency, the spleen, liver, gastrointestinal tract, pancreas, abdominal wall, genitourinary tract, adrenal, peritoneal cavity, and biliary tract are involved. However, a bone marrow biopsy is not needed in the early stages of the condition, Flow cytometry to identify cells as they flow through an instrument, called a flow cytometer.
