Recurrent intramedullary epidermoid cyst of spinal cord: A rare entity

Abstract

Epidermoid cysts of the spinal cord without spinal dysraphisms are rare lesions and intramedullary cysts are still rarer. Approximately only over 60 cases are reported in literature worldwide. Magnetic resonance imaging is the imaging modality of choice for the diagnosis of these lesions. Management of these lesions is by total surgical excision, although at times, it is not possible due to adherence of the capsule to the parenchyma of the spinal cord which may be the cause of recurrence. To our knowledge, this is the second case of recurrent intramedullary epidermoid cyst of spinal cord. We report a case of intramedullary epidermoid cyst which recurred after 7 years following near-total excision of tumor at our institute.
