Neuropathology of myelitis, myelopathy, and spinal infections in AIDS

Neuroimaging Clin N Am. 1997 Aug;7(3):639-50.

Abstract

In AIDS, pathology in the spinal contents usually follows that in the brain but is less frequent. Opportunistic infections are found in an average of 9.5% of spinal AIDS autopsies but in 54% of autopsies of the whole CNS. Necrotizing CMV radiculomyelitis is a rare (3.4% in spinal autopsies) but very characteristic opportunistic spinal lesion. The most prominent spinal cord disease in AIDS is vacuolar myelopathy, occurring in greatly differing frequencies according to different geographical areas, with a mean of about 22.5% in AIDS spinal cord autopsies. Its pathogenesis and clinicopathologic correlation need clarification; it appears to develop mainly in severely ill AIDS patients with significant viral load, advanced immunosuppression, and confounding metabolic imbalance.
