Abstract
INTRODUCTION AND IMPORTANCE: A gallbladder volvulus is a rare medical condition requiring emergency surgery. There are 500 cases reported in the literature, and only 10 % have ever been diagnosed preoperatively. Gallbladder volvulus occurs when the gallbladder torts around the cystic duct and cystic artery resulting in occlusion of both structures and consequently, ischemia of the gallbladder. The diagnosis is challenging because the symptoms mimic cholecystitis without distinct radiological features specific for a volvulus. CASE PRESENTATION: In this article, we report the case of a 77-year-old female who underwent ultrasonography (US), computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP), and cholescintigraphy, which all reported features of cholecystitis. She underwent a cholecystectomy on admission day 5 because of refractory pain despite treatment with intravenous antibiotics. Intraoperatively, she was discovered to have complete gallbladder torsion with gangrene. Post-operatively, she had immediate and complete resolution of pain, and made a rapid recovery. CLINICAL DISCUSSION: We review the available literature to determine radiological characteristics specific to a gallbladder volvulus. Patients without cholelithiasis and incomplete filling of the gallbladder in a nuclear medicine scan should be evaluated for gallbladder volvulus. CONCLUSION: Through this report, we suggest a high index of suspicion for gallbladder volvulus in elderly female patients with signs and symptoms of acalculous cholecystitis that have no resolution in symptoms with conservative management.
