Core Tip
Core tip: Rectal gastrointestinal stromal tumors (GISTs) are so rare that little information has been reported on their radiological features. This study describes the computed tomography (CT) and magnetic resonance imaging (MRI) features of rectal GISTs with clinical and pathological correlation, in order to better understand this rare disease. Rectal GISTs usually manifest as large, well-circumscribed, exophytic masses with moderate and heterogeneous enhancement on CT and MRI. The presence of invasion of adjacent organs, bowel obstruction and local adenopathy is uncommon.
