A 63-year-old woman with a history of malignant schwannoma in the left shoulder (pT1aNxMx) was treated with surgical resection in 2012. During follow-up, patient developed a metastasis in the right lung treated by further surgical intervention. For a suspicion on persistent disease in the lung, patient was sent to FDG PET/CT examination, which showed a focal uptake in the gallbladder. The patient underwent cholecystectomy, and a solitary metastasis from schwannoma was diagnosed by pathology. This case highlights that, in patients with a malignant schwannoma, a careful differential diagnosis should be made in case of a significant FDG uptake in the gallbladder.
一位 63 岁女性,曾于 2012 年因左肩部恶性神经鞘瘤(pT1aNxMx)接受手术切除治疗。在随访期间,患者右侧肺部发生转移,进一步接受了手术干预。由于怀疑肺部疾病持续存在,患者进行了 FDG PET/CT 检查,结果显示胆囊有局灶性摄取。患者随后接受了胆囊切除术,病理诊断为孤立性神经鞘瘤转移。本病例强调,对于患有恶性神经鞘瘤的患者,如果胆囊出现明显的 FDG 摄取,应仔细进行鉴别诊断。
