We present a case of spinal epidermoid tumour that was probably caused by lumbar punctures. The tumour was detected on MRI in a child with tuberous sclerosis complaining of atypical low back pain. Preoperatively the tumour was considered to be a cystic astrocytoma of ependymoma of the conus terminalis. The association of tuberous sclerosis with a spinal tumour is rare but has been recorded in the literature. The diagnosis was an epidermoid tumour (E.T.). The MRI appearances were unusual for a spinal ET: the signal intensity changes were different from those reported in the literature and the presence of calcification and cavitation has not yet been reported. This case represents a diagnostic pitfall, since both entities were unrelated.
我们报告一例可能由腰椎穿刺引起的脊髓表皮样肿瘤。该肿瘤在一名患有结节性硬化症且主诉非典型腰痛的儿童的磁共振成像（MRI）检查中被发现。术前该肿瘤被认为是终丝室管膜瘤的囊性星形细胞瘤。结节性硬化症与脊髓肿瘤的关联罕见，但文献中有记载。诊断结果为表皮样肿瘤（E.T.）。该脊髓表皮样肿瘤的MRI表现不常见：信号强度变化与文献报道不同，且钙化和空洞的存在尚未见报道。此病例是一个诊断陷阱，因为这两种情况并无关联。
