Epidermoids in the spinal canal are rare. They usually occur as a consequence of trauma or in the presence of an underlying dysraphism. Epidermoids are also usually seen in the lumbar region with an associated dorsal tract or sinus connecting them to the skin. We present an unusual case of a dorsal spinal epidermoid without any dysraphism, or history of trauma. The lesion was diagnosed on MRI and the lesion was completely excised surgically through a laminectomy and durotomy. Histopathological assessment confirmed the diagnosis of an epidermoid. To our knowledge this is the eighth such report in literature, making this an an usual and interesting report. A review on relevant literature is discussed in conjuction to this case as well.
