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.
嗜酸性粒细胞性胆囊炎（EC）是一种罕见疾病，其特征为胆囊壁有嗜酸性粒细胞浸润。我们报告一例35岁女性病例，该患者右上腹持续疼痛1个月。计算机断层扫描显示胆囊壁内层明显强化。同一区域的磁共振成像在T2加权成像上显示低信号强度。实施了胆囊切除术，手术标本的组织学检查显示，在浆膜下内层每高倍视野有超过100个嗜酸性粒细胞。这些组织学发现区域与计算机断层扫描确定的胆囊壁内层明显强化区域相对应。
