Abstract

Extragastrointestinal stromal tumors (EGIST) are relatively rare, and cases originating in the retroperitoneum even rarer. We report a 60-year-old woman who presented with an EGIST originating in the retroperitoneum. Computed tomography results demonstrated a soft tissue mass on the right side of the retroperitoneum. The tumor abutted the duodenum, head of the pancreas, and right kidney. The mass was surgically proven to be a retroperitoneal tumor and histopathologically proven to be a retroperitoneal EGIST.

Keywords: Extragastrointestinal Stromal Tumors, Retroperitoneum, Computed Tomography
