Pathologic features of brain in AIDS are all, except
Unlike most other viral encephalitides, HIV does not seem to infect neurons and perivasculitis is conspicuously absent" - Anderson pathology 10th/e p. 2728

Other characteristic pathologic feature of CNS in AIDS are :

Diffitse and focal spongiform changes
Vascular myelopathy of post column of spinal cord

Most characteristic finding is chronic inflammatory reaction with widely distributed infiltrates of microglial nodules.
Perivascular giant cell invasion
Microglial nodules
Vasculitis
Temporal lobe infarction
