DUODENAL SCHWANNOMA CAUSING GASTROINTESTINAL-BLEEDING - HELICAL CT FINDINGS

Neurogenic tumors of the small intestine are extremely rare and repres ent an unusual cause of gastrointestinal hemorrhage. We present a case of schwannoma of the fourth portion of the duodenum demonstrated by h elical computed tomography. Multiplanar reconstructions showed a hyper vascular tumor arising from the inferior wall of the duodenum. The use of water as oral contrast agent instead of iodinated contrast permitt ed a better visualization of the intact mucosa and differentiated a hy pervascular tumor from hypodense gastrointestinal content.
