Intramedullary Thoracic Epidermoid Cyst with Unusual Presentation

Abstract

Background: Epidermoid cyst are benign tumors from ectoderm remnants. Intramedullary epidermoid cysts are uncommon.

Case presentation: We present a 33 years old woman that was evaluated for acute low back pain and right leg radiculopathy. On examination she had right leg weakness and spastic gait. Lumbosacral MRI showed l5-s1 disc herniation that not justified all signs of the patients. The patients underwent thoracic MRI that showed an intramedullary lesion in the dorsal cord at T3-T4 level that had a pearly white appearance on exploration. Histologic examination demonstrated epidermoid cyst.

Conclusion: Epidermoid cyst can be considered in differential diagnosis of intramedullary tumors. Their removal leads to recovery.
