Epidermoid cyst inside anterior sacral meningocele in an adult patient of Currarino syndrome manifesting with meningitis.

The Currarino triad, also known as the "Currarino Syndrome", is a rare complex of congenital caudal anomalies including three main features; a sacral bony deformity, anorectal malformations, and a presacral mass. We present an extremely uncommon case of Currarino syndrome in adulthood presenting with repeated episodes of meningitis. Magnetic resonance imaging of spine was suggestive of caudal regression. Cord was low lying, conus ending at L3 level with evidence of tethering at that level. A large cyst was noted in the sacral canal extending forwards in the pelvis through the widened sacral foramina on right side. She was operated through a posterior approach, via sacral laminectomy. Dura was opened in the midline, large silvery white epidermoid tumor was found completely occupying the anterior sacral meningocele. The case and relevant literature is discussed.
