Depending on location and associated anomalies, it can be seriously complicated,for example: risk of compression on adjacent nervous system and it causes recurrent C.N.S infection. Case Report: A 33 months old boy was referred to our department with a 12 month history of left flank pain. MRI showed a solid tumor that located in conus medullaris (vertebral level Lj-T12). This condition last without neuralgic sign. Discussion: The epidermoid cyst can be either congenital or acquired. The acquired form of epidermoid cyst may be occurred after single or multiple lumbar punctures. Imaging evaluation of the patient revealed an interaspinal tumor.
