We report a case of thoracic exophytic myxopapillary ependymoma with imaging modality mimicking an intradural extramedullary tumour. This tumour showed hypointense relative to the spinal cord on T1-weighted (TR516/TE17) images and hyperintense on T2-weighted (TR4000/TE84) images. It revealed strong enhancement on T1-weighted (TR500/TE11) images. These findings were diagnosed as a meningioma by the radiologist. The tumour was proven to arise from the ventral side of the thoracic cord, and was totally excised. It was verified histopathologically as a myxopapillary ependymoma.
我们报告一例胸段外生性黏液乳头型室管膜瘤，其影像学表现酷似硬脊膜内髓外肿瘤。该肿瘤在T1加权（TR516/TE17）图像上相对于脊髓呈低信号，在T2加权（TR4000/TE84）图像上呈高信号。在T1加权（TR500/TE11）图像上显示明显强化。放射科医生将这些表现诊断为脑膜瘤。该肿瘤经证实起源于胸段脊髓腹侧，并被完整切除。组织病理学检查证实为黏液乳头型室管膜瘤。
