A Congenital Spinal Epidermoid Cyst

Neurologic pathologies of the vertebral spine

At some institutions, musculoskeletal and general radiologists rather than neuroradiologists are responsible for reading magnetic resonance imaging (MRI) of the spine. However, neurological findings, especially intrathecal ones, can be challenging. Intrathecal neurological findings in the spine can be classified by location (epidural, intradural extramedullary, and intramedullary) or etiology (tumor, infection, inflammatory, congenital). In this paper, we provide a succinct review of the intrathecal neurological findings that can be seen on MRI of the spine, primarily by location and secondarily by etiology, in order that this may serve as a helpful guide for musculoskeletal and general radiologists when encountering intrathecal neurological pathologies.

Concurrent Thoracic Spinal Intradural Extramedullary Epidermoid and Neurenteric Cyst in a Spinal Dysraphism Child

INTRODUCTION

Intraspinal epidermoid cysts are congenital or acquired in origin; whereas intraspinal neurenteric cysts (NECs) are of congenital origin. Their individual association with spinal dysraphism and vertebral segmentation anomalies is very well known.

CASE PRESENTATION

We hereby report a case of concurrent intradural extramedullary epidermoid and NEC at adjacent vertebral levels in a spinal dysraphism child, not reported in English Literature till now.

CONCLUSION

Multiple spinal lesions related to any/all of the 3 germ layers can coexist at same or adjacent vertebral levels in the same patient and surgical planning shown to be done accordingly.
