Gastrointestinal stromal tumours (GISTs) constitute a group of smooth muscle mesenchymal gastrointestinal tract tumours. These are found to originate from the interstitial cells of Cajal 2-3, with 95% staining positive for CD117 (c-KIT) and 70% for CD34. The former is highly responsive to the chemotherapeutic agent ST-571 (Imatinib). The lesion morphology varies according to location but usually they appear as rounded irregular soft tissue protrusions, arising from the wall of a hollow viscus (mostly stomach) projecting into the lumen. We report here a case of a fiftyyear-old male with complaints of a vague abdominal pain with nausea and occasional bouts of vomiting and present the imaging findings.
