Duodenal Flexure Pseudotumor

 At angle between bulb and descending duodenum

image Acute angulation as duodenum becomes retroperitoneal, accentuates fold
• May even simulate ulcerated mass, with barium trapped between mucosal folds
• Changeable appearance on upper GI fluoroscopy
image May disappear on upright or left decubitus positioning, or with compression
image Normal peristalsis
• Can simulate polypoid mass on CT as well
image CT has disadvantage of not allowing real-time evaluation of changes with peristalsis or different positions
image Pseudolesion has same imaging characteristics (enhancement) as remainder of duodenal mucosa
