Splenic sarcoidosis

Abstract

Sarcoidosis is a multisystem granulomatous disease of unknown cause that can produce either homogeneous splenomegaly or multiple splenic nodules. Systemic symptoms can accompany splenic involvement. Although the chest radiograph may be suggestive of sarcoidosis, a normal chest radiograph is seen in one quarter to one third of patients with splenic sarcoidosis. The imaging appearance of splenic sarcoidosis can mimic more ominous neoplastic or infectious disease. Biopsy of the spleen or other involved organ may be indicated for definitive diagnosis.
