Disseminated Microinfarctions with Cerebral Microbleeds.

Disseminated microinfarctions are uncommonly encountered in clinical practice. Here we describe a patient with long-standing cerebral microbleeds who developed acute cognitive decline in the setting of acute hypotension. Magnetic resonance imaging showed acute disseminated microinfarctions, with no change in microbleeds. This case emphasizes the important relationship between ischemic and hemorrhagic microvascular disease of the brain, especially in the setting of acute blood pressure changes compounding preexisting microvascular injury.
