Abstract
The authors report and discuss a rare case of a gastrointestinal stromal tumor (GIST) in a 35-year-old female, which was pre-procedurally characterized as a right ovarian mass by magnetic resonance imaging (MRI) features. This manuscript reviews the imaging and clinical features of GISTs with pathologic correlation, and emphasizes how this entity may present a diagnostic challenge in certain anatomic regions owing in large part to its exophytic nature. This case is unique among similarly reported cases in that there was a "claw sign" with the right ovary, which provided convincing evidence of its point of origin.
