摘　　要：椎管内转移瘤是一种少见的从全身各部位恶性肿瘤转移至椎管内的恶性肿瘤。常见的椎管内转移瘤多位于硬膜外,原发灶多为肺脏、前列腺等,原发灶为胸腺癌的髓外硬膜下转移瘤十分罕见,既往报道的病例影像学表现与原发性椎管内肿瘤也存在一定重叠性,非常容易误诊。现报道胸腺癌椎管内转移瘤1例,主要诊断线索包括:(1)胸腺癌病史;(2)生长速度快;(3)形态不规则。Intraspinal metastasis from malignant carcinomas in other body parts is rarely reported.Intraspinal metastases are often epidural,with primary tumors mostly from the lung and prostate.The extramedullary subdural metastasis of thymic carcinoma is particularly rare and prone to misdiagnosis due to overlapping imaging features with primary intraspinal tumors.This article reports one case of intraspinal metastasis of thymic carcinoma,with the main diagnostic clues including a history of thymic carcinoma,fast growth rate,and irregular shape.
