AbstractJuvenile Xanthogranuloma (JXG) is a rare disorder of central nervous system. It rarely produces compressive myelopathy. On reviewing world literature, we could find only nine cases of this disease involving spine and of which only four cases were in adults' i.e., 18 years and above. We are presenting a case of Spinal JXG in an 18-year-old male with thoracic compressive myelopathy presenting as short duration progressive paraparesis. Magnetic Resonance Imaging of Spine showed mass lesion in epidural space compressing cord from behind without any bony involvement at D7 to D10 vertebral segment. It was isointense on T1 and hyperintense on T2 with no contrast enhancement. D7 to D10 Laminectomy with complete excision of firm epidural mass was carried out. The histopathology with tumor markers confirmed the diagnosis of JXG. Post-operative neurological recovery in this patient was good. His power improved to grade 5/5 with decreased spasticity. Follow-up MRI at 3 months showed no residual tumor. This case appears to be the first in the series with entirely extradural component in adult thoracic spine.
