Gallbladder ciliated foregut cysts (CFCs) of the lower diaphragm are extremely rare. Furthermore, they are rarely suspected of malignancy preoperatively. . A 50-year-old woman was referred to our hospital for further examination and treatment of a gallbladder tumor that was detected using abdominal ultrasonography (US). After a close inspection, she was diagnosed with a gallbladder tumor that was possibly malignant. Accordingly, open whole layer cholecystectomy was performed because intraoperative US revealed a tumor located on the intraperitoneal side of the gallbladder, and a rapid intraoperative pathological diagnosis identified no malignancy. A postoperative pathological examination revealed a cystic lesion with thin walls covered with ciliated epithelium, which laid on a connective tissue with smooth muscle fibers. Based on the above results, the final pathological diagnosis was CFC of the gallbladder without malignancy.
Cases of gallbladder CFC can be considered as cysts requiring treatment owing to CFCs' potential for malignant transformation and high-frequency symptoms.
位于膈肌下方的胆囊纤毛前肠囊肿（CFC）极为罕见。此外，术前很少怀疑其为恶性。一名50岁女性因腹部超声检查发现胆囊肿瘤而被转诊至我院进一步检查和治疗。仔细检查后，她被诊断为可能为恶性的胆囊肿瘤。因此，由于术中超声显示肿瘤位于胆囊腹膜侧，且术中快速病理诊断未发现恶性肿瘤，遂行开放性全层胆囊切除术。术后病理检查显示为囊性病变，薄壁被覆纤毛上皮，位于含有平滑肌纤维的结缔组织上。基于上述结果，最终病理诊断为无恶性的胆囊CFC。
由于胆囊CFC有恶变潜能且症状频发，胆囊CFC病例可被视为需要治疗的囊肿。
