A Case of Intradural, Extramedullary Tuberculous Granuloma Developed During the Treatment of Tuberculous Meningitis

ABSTRACT

A 24-year-old man was treated with anti-tuberculous therapy after being diagnosed with tuberculous meningitis. However, he developed abrupt onset of weakness in the lower extremities. Thoracic spinal magnetic resonance imaging (MRI) showed a soft tissue mass, a compressed posterior spinal cord. A total resection of the intradural extramedullary mass was performed. A histological examination revealed the infiltration of inflammatory cells with granulomatous lesions. Intradural extramedullary tuberculous granuloma is rare, but must be considered in the differential diagnosis of spinal cord compression.
