A Rare Case of Retroperitoneal Sarcoidosis

Abstract

Sarcoidosis is a systemic granulomatosis of undetermined etiology characterised by the formation of epithelioid and gigantocellular granulomas without caseous necrosis in the affected organs. Our case has a history of sarcoidosis with left flank pain. CT scan founded a left hydronephrosis secondary to a retroperitoneal mass encasing the lumbar ureter which was shunted by a double j stent. Biopsy of the mass showed fibrous tissue with epithelioid and gigantocellular granuloma without caseous necrosis. Our patient is an extremely rare case report.
