[Case of epidural tuberculosis of the vertebral canal]

A patient aged 16 years was admitted to a neurological departement for flaccid paresis of lower extremities. Contrast radiological examination demonstrated obliteration of the vertebral canal between Th12 and L3, without coexistent changes in the bone parts of the vertebral column on plain films. During the operation a tumour situated epidurally and compressing the dural sac posteriorly and laterally from both sides at the level Th12--L3 was removed. Histological examination of the excised tumour showed presence of a chronic inflammatory process with presence of granulation tissue of probably tuberculous character. The tuberculous aetiology of the disease was confirmed by development of cold abscess in the postoperative scar 2 months after the operation. Neurological, neurosurgical and antituberculous treatment led to complete cure with return of normal neurosurgical status. The patient has been followed up for 5 years.
