Abstract

Epidermoid cyst is a frequently encountered cutaneous or subcutaneous cyst. Non-(sub)cutaneous epidermoid cysts are rarely found. We present a case of a 60-year-old man with an incidental mass in the left flank which turned out to be a preperitoneal located epidermoid cyst. This is, to the best of our knowledge, the first citation of an epidermoid cyst in the preperitoneal space in literature. Ultrasound, CT, and MRI were performed, but MRI gave the final clue to the diagnosis. Resection was performed and histopathologic analysis confirmed the radiologic diagnosis of an epidermoid cyst.

Keywords: Epidermoid cyst; MRI; Preperitoneal; Ultrasound.
