Abstract:
Eosinophilic cholecystitis (EC) is a rare condition that is characterized by eosinophilic infiltration in the gallbladder wall. We report the case of a 35-year-old woman who presented with unremitting right upper quadrant pain for 1 month. Computed tomography showed a strongly enhanced inner layer of the gallbladder wall. Magnetic resonance imaging of the same area showed low signal intensity on T2-weighted imaging. Cholecystectomy was performed, and histological examination of the surgical specimen revealed >100 eosinophils per high-power field in the inner subserosal layer. The area of these histological findings corresponded to the strongly enhanced inner layer of the gallbladder wall identified on computed tomography.
