The occurrence of epidermoids within the spinal canal is uncommon. Most of the reported spinal epidermoids (SEs) have been described in the thoracic or lumbar regions. They occur either following trauma or in the setting of coexistent spinal dysraphism. The authors describe an unusual case of a 28-year-old lady who presented with long-standing back pain and urinary incontinence. Magnetic resonance imaging (MRI) of her spine demonstrated a sacral SE without any coexistent spinal dysraphism. The diagnosis of an epidermoid was confirmed by histopathological examination following laminectomy and excision. To the authors' best knowledge, this is the third case of a sacral SE occurring in a non-dysraphic spine. The case is discussed in the light of a relevant literature review.
椎管内表皮样囊肿的发生并不常见。大多数已报道的脊柱表皮样囊肿（SEs）见于胸段或腰段。它们要么发生在创伤后，要么存在于并存的脊柱发育异常的情况下。作者描述了一例不寻常的病例，一名28岁女性，长期存在背痛和尿失禁。她的脊柱磁共振成像（MRI）显示为骶部SE，无并存的脊柱发育异常。椎板切除和切除术后的组织病理学检查证实为表皮样囊肿。据作者所知，这是第三例发生在无发育异常脊柱的骶部SE。结合相关文献综述对该病例进行了讨论。
