Intradural tuberculosis granuloma is a tuberculous granuloma that occurs in the spinal cord or extramedullary subdural or epidural, excluding paravertebral abscesses caused by spinal tuberculosis involving the spinal canal. Clinical manifestations include fever, body temperature 38-40 ℃, sensory-motor impairment of the limbs, choking and coughing with water, headache, segmental girdling in the thoracic and abdominal segments, and urinary and fecal dysfunction in the lumbosacral region, manifested as constipation and urinary incontinence or urinary retention. The lumbosacral region may be associated with urinary and fecal dysfunction, including constipation and urinary incontinence or retention. MRI manifestations: Extramedullary subdural tuberculous granuloma shows slightly long or long T1 and T2 signals, and the granuloma and the adjacent dura mater show fusion and adhesion on imaging. The intramedullary type shows thick-walled circumferential enhancement. Intradural tuberculous granuloma adjacent to the spinal cord with edema or inflammation, swelling of the spinal cord, and abnormal signals are seen. In the case of tuberculous granuloma of the lumbosacral segment, the cauda equina nerve aggregates in the lumbar pool, the subarachnoid space is occluded, and the spinal cord surface is irregularly shaped, with linear strengthening of the spinal cord and cauda equina surface seen on enhancement scans. Once limb weakness and numbness, urinary incontinence, and prolonged constipation occur during the course of anti-tuberculosis treatment, spinal cord-related tests should be performed promptly, and if there are positive results, surgical treatment should be performed promptly.
