[Acute cholecystitis using computed tomography: usefulness of the trabeculation of the peri-cholecystic adipose tissue]. / Cholécystite aiguë en tomodensitométrie: utilité de la trabéculation de la graisse périvésiculaire.

ABSTRACT

PURPOSE: To evaluate the significance of pericholecystic fat stranding on CT, and to compare it to other CT findings in patients with acute cholecystitis. MATERIALS AND METHODS: The CT examinations of 14 patients with proven acute cholecystitis were retrospectively reviewed and evaluated for the presence of findings consistent with this diagnosis. RESULTS: The most common CT finding was stranding of the pericholecystic fat (13 patients), followed by gallbladder distension (11 patients). Pericholecystic or perihepatic fluid was present in 6 patients in association with severe acute cholecystitis (6 patients) and biliary peritonitis (2 patients). CONCLUSION: Stranding of the pericholecystic fat was the most common CT findings in patients with acute cholecystitis, followed by gallbladder distension.
