Gastric Angiolipoma Causing Partial Duodenal Obstruction: A Rare Cause of Chronic Abdominal Pain

Background: Gastric angiolipomas are extremely rare benign tumors, often presenting with nonspecific symptoms such as abdominal pain and vomiting. Their diagnosis is challenging due to overlapping features with other gastrointestinal pathologies.Case Presentation: We report a 38 to 40 year old female with one-month history of epigastric pain radiating to the back, nausea, vomiting, and constipation. Initial workup revealed iron-deficiency anemia, elevated inflammatory markers, and abnormal liver enzymes. CT scan demonstrated a pedunculated gastric mass telescoping into the duodenum, causing partial obstruction and pseudo-obstruction of the common bile duct. Oesophagoduodenoscopy confirmed a large gastric mass prolapsing in the duodenum and had ulceration at the head. The patient underwent laparoscopic reduction of the migrated mass and fundectomy. Histopathology revealed an angiolipoma composed of mature adipocytes and vascular channels. Postoperative recovery was uneventful.Conclusion: Gastric angiolipoma is a rare entity that should be considered in patients with unexplained abdominal pain and obstructive symptoms. Early imaging and endoscopic evaluation are crucial for diagnosis and surgical planning.
