[Role of the vascular factor in the clinical picture and pathologic anatomy of chronic spinal leptopachymeningitis of tuberculous etiology].

Under observation there were 16 patients with chronic leptopachymeningitis of tuberculous etiology. The disease got complicated with ischemic disturbance of the spinal circulation which developed acutely in 5, and chronically in 14 patients. The clinical manifestations corresponded to the level of the ischemic lesion in the spinal cord and the disease course. Isotopic myelography revealed a complete blocking of the subarachnoidal space. In the cerebrospinal fluid a relative protein-cell dissociation was observed. Pathomorphological examinations of the spinal cord revealed in 5 cases an ischemic decay of the cord and formation of cavities at the level of lymphoid infiltrations to the meninges or of vascular affections.
