Intramedullary dorsal dermoid cysts are rare benign tumors, arising from the nests of embryonic ectoderm, which get buried or trapped under the lines of fusion of the ectodermal folds in the developing embryo. We present a rare case of intramedullary dermoid cyst in a 30-year-old asymptomatic female, who presented with paraplegia and ataxia. Magnetic resonance imaging was suggestive of neoplastic intramedullary mass. Intraoperatively, findings were suspicious of tuberculosis, but on final histopathological evaluation, the final and definitive diagnosis of intramedullary dermoid cyst was rendered. The postoperative phase was uneventful.
髓内背侧皮样囊肿是一种罕见的良性肿瘤，起源于胚胎外胚层巢，在发育中的胚胎中被埋入或困于外胚层褶皱融合线之下。我们报告一例罕见的30岁无症状女性髓内皮样囊肿病例，该患者出现截瘫和共济失调。磁共振成像提示髓内肿瘤性肿块。术中发现怀疑为结核病，但最终经组织病理学评估，确诊为髓内皮样囊肿。术后恢复顺利。
