Abstract
A case of inflammatory polyp of the gallbladder accompanied localized Adenomyomatosis is reported. A 72-year-old woman who was pointed out having 2 gallbladder polyps was admitted to the hospital. Abdominal ultrasonography (US) and Computed tomography (CT) showed a polyp on adenomyomatosis at the fundus, a semi pedunculated polyp at the body of the gallbladder. Endoscopic ultrasonography (EUS) showed that the polyp at the fundus was pedunculated. A laparoscopic cholecystectomy was carried out. Histopathological studies of resected gallbladder indicated that the lesion was inflammatory polyp. We thought that the mechanism of development was highly suggestive.
