Intradural extramedullary tuberculoma of the thoracic spine: Paradoxical response to antituberculous therapy

Intradural extramedullary tuberculoma of the spinal cord (IETSC) is a rare complication of tuberculosis, which can occur as a paradoxical response to antituberculous therapy. A 46-year-old woman with tuberculosis meningitis developed an acute sensory disturbance and paraplegia eight weeks after the antituberculous treatment was started. MRI revealed a cystic lesion at the Th 2 and 3 vertebrae levels, and continuous dural thickening. Laminectomy was performed; soft granulomas were unexpectedly observed inside the dura matter. After the operation, the patient experienced progressive improvement in motor strength. IETSC should be known as rare but possible complication of tuberculous meningitis.
