Schwannoma is a rare source of false-positive 18F-fluorodeoxyglucose (18F-FDG) uptake in Positron-emission tomography (PET/CT), inducing potential errors in staging of several solid cancer, with implications for patient management. This clinical case reports the situation of a patient undergoing an 18F-FDG-PET/CT for initial staging of an ovarian adenocarcinoma. We found a high paramediastinal hypermetabolic mass suspicious of remote extension or secondary synchronous primitive tumor. The biopsy finally reveals a histopathology of Schwannoma, allowing the patient to be eligible for a surgical procedure of her ovarian adenocarcinoma by rejecting the hypothesis of malignancy.
神经鞘瘤是正电子发射断层扫描（PET/CT）中18F-氟脱氧葡萄糖（18F-FDG）摄取出现假阳性的罕见原因，可在几种实体癌的分期中导致潜在错误，对患者管理产生影响。本临床病例报告了一名接受18F-FDG-PET/CT检查以对卵巢腺癌进行初始分期的患者的情况。我们发现一个高代谢的纵隔旁肿块，怀疑有远处转移或继发性同步原发性肿瘤。活检最终显示为神经鞘瘤的组织病理学结果，排除了恶性肿瘤的假设，使患者有资格接受卵巢腺癌的手术治疗。
