Brunneroma: A Rare Cause of Duodeno-duodenal Intussusception.

: Brunner gland hamartoma (brunneroma) is a rare benign tumor of the duodenum. It is usually asymptomatic and detected incidentally by endoscopy or other imaging modality. The definitive diagnosis is based on histopathological findings. These may mimic tumors of other natures, such as gastrointestinal stromal tumors (GIST), carcinoids, lipomas, and leiomyomas. Here, we present a case of duodenal polyp presenting with abdominal pain and obstructive symptoms that caused duodenal intussusception. It was surgically removed and found to be a brunneroma on histopathology. Patankar AM, Wadhwa AM, Bajaj A, Ingule A, Wagle P. Brunneroma: A Rare Cause of Duodeno-duodenal Intussusception.
