We report the case of a pelvic malignant peripheral nerve sheath tumor mimicking an adnexal mass. A 59-year-old postmenopausal woman presented with a 3-month history of diffuse abdominal bloating and urinary frequency. Laboratory tests revealed an increased CA 125. Radiologic evaluation depicted a large, heterogeneous solid mass located right to the uterus, pushing it to the left. After a multidisciplinary board discussion, the diagnosis of a right adnexal lesion was assumed, and the patient was referred to surgery. The final diagnosis was only achieved after pathology examination, which prove to be a malignant peripheral nerve sheath tumor. This paper highlights some clinical, radiologic and pathological features of malignant peripheral nerve sheath tumors, a rare entity that should be considered as a differential in patients presenting with pelvic tumors of uncertain origin.
我们报告了一例盆腔恶性外周神经鞘瘤，其表现类似附件肿块。一名59岁的绝经后女性，有3个月弥漫性腹胀和尿频的病史。实验室检查显示CA 125升高。影像学评估显示子宫右侧有一个大的、不均匀的实性肿块，将子宫推向左侧。经过多学科会诊讨论，考虑诊断为右侧附件病变，患者被转诊接受手术。最终诊断仅在病理检查后得以明确，结果证实为恶性外周神经鞘瘤。本文强调了恶性外周神经鞘瘤的一些临床、影像学和病理特征，这是一种罕见的疾病，对于起源不明的盆腔肿瘤患者应将其作为鉴别诊断之一。
