Schwannomas are benign tumors which arise in the Schwann cells of the peripheral nerves. They develop anywhere in the human body but are less frequent found in the digestive tract. A 67-year-old female patient was referred to our tertiary HPB department with a asymptomatic mass of the gallbladder. Contrast-enhanced computed tomography revealed a rather homogeneous, well-circumscribed, high-density ovoid mural mass. An open cholecystectomy was performed. A final diagnosis of schwannoma with degenerative atypia, so-called "ancient schwannoma", was made. Clinical recovery and follow-up was uneventful, with no signs of recurrence.
施万细胞瘤是起源于周围神经施万细胞的良性肿瘤。它们可发生于人体任何部位，但在消化道中较少见。一名67岁女性患者因胆囊无症状肿块被转诊至我院三级肝胰胆外科。增强计算机断层扫描显示胆囊壁有一个相当均匀、边界清晰、高密度的椭圆形肿块。实施了开放性胆囊切除术。最终诊断为伴有退行性异型性的施万细胞瘤，即所谓的“陈旧性施万细胞瘤”。临床恢复和随访过程顺利，无复发迹象。
