title: Complete body-neck torsion of the gallbladder: a case report.
abstract: Gallbladder torsion is a rare, acute abdominal disease. It was first reported by Wendell in 1898. Since then, only 500 cases have been reported. Gallbladder torsion occurs in all age groups, although it usually appears in the latter stages of life. The occurrence ratio between women and men is 3:1. Most cases are diagnosed during surgery. The main treatment is surgical detorsion and cholecystectomy. Despite progress in radiologic imaging diagnosis, it is not easy to obtain a precise preoperative diagnosis of gallbladder torsion. In previous reports, only 9.8% of all gallbladder torsion cases were diagnosed preoperatively. We present a case of acute body-neck gallbladder torsion in an elderly man, and we review the radiologic findings of magnetic resonance imaging, computed tomography, and ultrasonography. The radiologic findings in the present case were helpful in obtaining a preoperative diagnosis of gallbladder torsion. The diagnosis was confirmed by T2-weighted magnetic resonance images, which showed an intra-gallbladder segment located between the body and neck of the gallbladder, with a notable crease within this segment.
