Diagnosis With Brief Discussion

Diagnosis
Sarcoidosis
Radiologic Findings
Chest radiographs show nodular bulging contour in left paratracheal area, AP window and left hilum. CT scan shows lymph node enlargement in mediastinum, both hilum, axilla, internal mammary area and retrocrural area in thorax. Lymphadenopathy is also noted in paracaval, paraaortic area, splenic hilum and mesentery in abdomen. Splenomegaly is also seen. Excisional biopsy of axillary lymph node revealed chronic noncaseous granulomatous inflammation compatible with sarcoidosis.
Brief Review
Sarcoidosis is a systemic disorder of unknown cause that is characterized by noncaseating granulomas with proliferation of epithelioid cells. Bilateral hilar lymphadenopathy is the most common radiologic finding. Adenopathy in the right paratracheal nodes, left aortic-pulmonary window, and subcarinal nodes can also be seen, often with associated pulmonary infiltrates.

However, extrathoracic involvement can be an initial manifestation in one-half of symptomatic patients. Although skin and ocular lesions are common, the liver, spleen, lymph nodes, parotid glands, central nervous system (CNS), genitourinary system, muscles, and bones may also be involved. Massive abdominal lymphadenopathy in the paraaortic region is rare but may be encountered in patients with systemic sarcoidosis. Imaging findings in these nodes are usually nonspecific, and differentiation from metastatic carcinoma or malignant lymphoma may be difficult. According to a report that compare lymph node involvement in sarcoidosis and lymphoma, retrocrural, paracaval/paraaortic, and pelvic lymph node enlargement are more frequently seen in lymphoma than sarcoidosis. Mean size of lymph nodes is larger in lymphoma than in sarcoidosis. Confluent mass formation is more common in lymphoma than sarcoidosis.
