Abstract:
Objective To investigate the diagnostic values of CT in xanthogranulomatous cholecystitis (XGC).Methods Retrospective analysis was performed in 4 patients with pathology confirmed XGC. Abdomen CT scans with and without contrast enhancement were performed in all patients. Results Only 1 case was correctly diagnosed before surgery. CT findings included gallbladder enlargement (3 patients), gallbladder wall thickening ( 4 patients), gallstone (1 patient), and common bile duct stone (1 patient). The maximum wall thickness was between 4 mm and 30 mm, with irregular low-density layer inside. Mucosal line was normal in 2 and pericholecystic infiltration in 1. After contrast administration, hypodense band sign was revealed in 2 and rim enhancement sign around the nodules was shown in 1 at arterial phase. Conclusion CT features of hypodense band sign and rim enhancement sign around the nodules in the arterial phase of contrast enhanced CT are strongly suggestive of XGC.
