A 38-year-old woman presented with a 12-month history of subjective weakness and pain in her legs. Thoracolumbar MRI revealed two spinal intradural cystic lesions at T5-6 and T11 levels, respectively. The lesion located at the T5-6 level was heterogeneously hyperintense on T2-weighted images and heterogeneously hypointense on T1-weighted images. This lesion showed high signal intensity on diffusion weighted MRI (DWI) and low signal intensity on apparent diffusion coefficient images (ADC). According to the MRI findings, we reported this tumour as a spinal epidermoid cyst. The pathology result suggested that the lesion was an epidermoid cyst. The second intradural lesion, at the T11 level, showed a hypointense signal on T1 and hyperintense signal on T2 images. However, in contrast to the superior lesion, this lesion was hypointense on DWI and hyperintense on ADC. We evaluated the second lesion as an arachnoid cyst according to the MRI findings.
一名38岁女性，自述腿部乏力和疼痛12个月。胸腰椎磁共振成像（MRI）显示，分别在T5 - 6和T11水平有两个脊髓硬膜内囊性病变。位于T5 - 6水平的病变在T2加权图像上呈不均匀高信号，在T1加权图像上呈不均匀低信号。该病变在扩散加权MRI（DWI）上呈高信号，在表观扩散系数图像（ADC）上呈低信号。根据MRI表现，我们将此肿瘤报告为脊髓表皮样囊肿。病理结果提示该病变为表皮样囊肿。第二个硬膜内病变位于T11水平，在T1图像上呈低信号，在T2图像上呈高信号。然而，与上部病变不同的是，该病变在DWI上呈低信号，在ADC上呈高信号。根据MRI表现，我们将第二个病变评估为蛛网膜囊肿。
