Cervicodorsal dermoid cyst

ABSTRACT

Dermoid cyst is a slow growing benign true hamartoma. It is more common intracranially but comprises 0.7% of all the spinal tumours. Cervicothoracic region is an uncommon site of occurrence of this tumour. Authors present a large intradural dermoid cyst in cervicodorsal region. A 13-year-old boy presented with gradual onset ascending spastic weakness involving both the lower limbs. Magnetic resonance imaging of cervicodorsal region revealed intraspinal intradural extramgdullary cystic lesion extending from C6 - D6 level. C5 - D7 laminotomy and laminoplasty with total excision of the dermoid cyst was done. Here, we report a large intradural dermoid cyst at unusual site with relevant review of literature
