Diagnosis With Brief Discussion

Diagnosis
Diffuse large B cell lymphoma involving, left thyroid, right lung and terminal ileum. (tissues confirmed in all three areas)
Radiologic Findings
Chest radiograph shows fibrostreaky density on left upper lobe which suggests stable tuberculosis. At CT scan, there is a nodule with pseudocavity in right lower lobe. Thyroid ultrasound was done for evaluation of low density nodule which was found on CT. At ultrasound, the nodule is about 15 mm in size and with well-defined smooth border which is predominantly cystic and with hypoechoic debris This is indeterminate findings for malignancy. Abdomen CT shows circumferential wall mass at ileum without obstruction. PET-CT, MIP imaging shows three FDG-avid lesions in left thyroid, right lung and right lower abdomen with SUVmax of 5, 12 and 28 each.
Brief Review
Lymphomas are a diverse group of neoplastic disorders. They are divided into Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) and further subdivisions depend on the histologic types. The presence and distribution of thoracic involvement are important in both tumor staging and treatment, especially when radiation therapy is planned. Intrathoracic involvement is commoner in HL than NHL. Although HL represents only 10% to 15% of all cases of lymphomas, approximately 85% of patients with HL have intrathoracic disease at presentation. NHL represents about 85% to 90% of all cases of lymphoma and approximately 40% to 45% of patients with NHL have intrathoracic disease at the initial presentation. Although HL and NHL may have overlapping imaging findings, there are some significant differences in their radiologic features.

NHL has a worse prognosis than HD. Unlike HD, which commonly spreads through contiguous groups of lymph nodes, NHL is infrequently localized at the time of diagnosis and frequently involves extranodal sites of disease. NHL can be divided into two groups: indolent lymphomas, which grow more slowly and have fewer symptoms (eg, follicular lymphoma, MALT), and aggressive lymphomas, which grow more quickly (eg, diffuse large cell lymphoma, Burkitt's lymphoma, Mantle cell lymphoma).

Diffuse large B-cell lymphoma is the most common of the non-Hodgkin lymphomas, accounting for up to 30 percent of newly diagnosed cases. Diffuse large B-cell lymphoma is an aggressive, or fast-growing lymphoma. It can arise in lymph nodes or outside of the lymphatic system, in the gastrointestinal tract, testes, thyroid, skin, breast, bone or brain. Often, the first sign of diffuse large B-cell lymphoma is a painless or even painful rapid swelling in the neck, armpit or groin caused by enlarged lymph nodes. Other symptoms include night sweats, unexplained fevers and weight loss.
