Abstract

Spinal epidermoid cysts occur as a result of anomalous implants of epidermal cells within the spinal cord. Spinal epidermoid cysts comprise < 1% of all intraspinal mass lesions and may be congenital or acquired. Congenital lesions usually occur at conus or cauda equina, and the latter usually occur at lower lumbar spine. The typical MR appearance of a spinal epidermoid cyst is a hypointense signal lesion on T1-weighted images and a hyperintense signal lesion on T2-weighted images. However, atypical imaging features also have been reported. In this article, we report atypical MR findings of an intradural epidermoid cyst at conus medullaris and cauda equina of the spine that was caused by internal cystic hemorrhage.
