Summary

Cerebrovascular lesions were seen in 28 of 83 cases (34%) of acquired immune deficiency syndrome (AIDS). Cerebral hemorrhage was noted in 4 cases, cerebral infarct in 23 cases and both in 1 case. Cerebral hemorrhage was in various locations such as intraparenchymal, subarachnoid space, subdural space and epidural space. Large, clinically evident hemorrhage was noted in 2 of 5 cases and bleeding tendency was noted in 2 cases. Most of the 24 cases with cerebral infarcts were not clinically evident; they were multiple, small and mainly involved the striatum, cerebral cortex and brain stem. Mural thickening of occasional small blood vessels was seen in 12 of the cases (50%) with infarcts. Other changes in blood vessels included vasculitis in one cases and perivascular lymphocytic infiltration in another. In addition to thrombo-embolism and systemic ischemia/anoxia, these blood vessel changes may have a role in the development of cerebral infarcts in AIDS.
