Tuberculous radiculomyelitis (TBRM) is a complication of tuberculous meningitis (TBM), which has been reported rarely in the modern medical literature. We describe a case of TBRM, which developed during the treatment of TBM. A 28-year-old man suddenly developed lower back pain, flaccid paraparesis, urinary incontinence, while the TBM was improving with the treatment at 9th day after admission. Spinal MRI revealed leptomeningeal enhancement along with thoracolumbar spinal canal, thickening of nerve roots, spinal meninges and intramedullary high signal lesion in T2 level.
