| Summary: | Abstract Background Cholecysto-enteric fistula is a rare complication of cholelithiasis and cholecystitis. Another even rarer complication is proximal impaction of gallstone(s) in gastric pylorus leading to gastric outlet obstruction, known as the Bouveret Syndrome. Only a few cases have been reported in the available literature. It can be confused with a malignant thickening at the pylorus, knowledge of this syndrome helps in arriving at the right diagnosis. Case report A 52-year-old female patient, who was admitted to our hospital for evaluation of recurrent vomiting and abdominal pain. She was investigated with various imaging modalities including upper gastrointestinal (GI) endoscopy, abdominal ultrasonography as well as Contrast Enhanced Computerized Tomography (CECT) scan of the abdomen. On the outside scan, it was given as a malignant thickening at the pylorus. However, current radiologists felt that imaging findings were not of a typical malignant mass, and suspicion of Bouveret syndrome was given. Intraoperative findings confirmed the diagnosis of Bouveret syndrome. The patient has not experienced any postoperative complications till now. Conclusion Bouveret syndrome is associated with significant morbidity and mortality. Being familiar with the imaging appearance of this condition, and differentiating it with malignant thickening can help radiologists avoid unnecessary invasive procedures in such patients. Being a benign etiology, it also helps in a better prognosis.
