A schwannoma of the gallbladder is an extremely rare tumor. We report a case of a 45-year-old woman with a polypoid mass in her gallbladder. The mass was discovered incidentally as a heterogeneous enhancing mass in the infundibulum of the gallbladder on an abdominal CT scan performed during an evaluation of a reported nonspecific left lower abdominal pain. An ultrasonography revealed that the overlying mucosa of gallbladder was intact. Moreover, a laparoscopic cholecystectomy was performed and the mass was confirmed as a gallbladder schwannoma.
