Gallbladder torsion resulting in gangrenous cholecystitis within a parastomal hernia: findings on unenhanced CT

Jessica K Rosenblum et al. J Radiol Case Rep. .

Abstract

Gallbladder torsion is a rare cause of acute gangrenous cholecystitis; its occurrence within an abdominal hernia has not been previously reported. We present such a case occurring within a parastomal hernia and imaged with unenhanced CT.

Keywords: acute cholecystitis; gallbladder torsion; gallbladder volvulus; gangrenous cholecystitis; parastomal hernia.

Figure 1
76 year-old man with gallbladder torsion in a parastomal hernia. Findings: Markedly distended and thick-walled gallbladder with gallstones, intramural and intraluminal gas (arrows) in a right lower quadrant parastomal hernia. The gallbladder neck is elongated and deformed; however, the twist is not clearly appreciated due to lack of intravenous contrast. Technique: Reconstructed axial (a), sagittal (b) and coronal (c) unenhanced CT with oral contrast, mAs 181, kV 120, slice thickness 5 mm.
