Résumé
Intramedullary dermoid cysts within the spine are a rare benign tumor. We present this case, which has atypical presenting symptoms, in order to increase awareness of intradural dermoid cysts. We present here a case of a 42 year old man with a 12-month history of lumbar spinal pain as well progressive left lower extremity loss of strength, as well as numbness and paresthesia radiating into the left foot. Magnetic resonance imaging scan revealed a 4 × 1 × 1.3cm intradural mass at the cauda equina L1-L2 region and was hyperintense in both T1 and T2 causing cord compression. L1-L2 laminectomy and intradural micro resection were performed with successful excision of the suspicious mass. Histopathological review revealed keratinaceous debris and adnexal structures consistent with a dermoid cyst. Our case is unusual with the other reported cases of dermoid cysts due to superior involvement in the lumbar region compared to other case reports with predominantly lumbosacral involvement. This location of the cyst lead to radicular symptoms, rather than lumbosacral pain and sphincter incompetence that is more commonly represented in the literature.

Background
UNASSIGNED
Intramedullary dermoid cysts within the spine are a rare benign tumor. We present this case, which has atypical presenting symptoms, in order to increase awareness of intradural dermoid cysts.
Clinical presentation
UNASSIGNED
We present here a case of a 42 year old man with a 12-month history of lumbar spinal pain as well progressive left lower extremity loss of strength, as well as numbness and paresthesia radiating into the left foot. Magnetic resonance imaging scan revealed a 4 × 1 × 1.3cm intradural mass at the cauda equina L1-L2 region and was hyperintense in both T1 and T2 causing cord compression. L1-L2 laminectomy and intradural micro resection were performed with successful excision of the suspicious mass. Histopathological review revealed keratinaceous debris and adnexal structures consistent with a dermoid cyst.
Conclusions
UNASSIGNED
Our case is unusual with the other reported cases of dermoid cysts due to superior involvement in the lumbar region compared to other case reports with predominantly lumbosacral involvement. This location of the cyst lead to radicular symptoms, rather than lumbosacral pain and sphincter incompetence that is more commonly represented in the literature.
