Intra‐arterial spread of Mucormycetes mediates early ischemic necrosis of brain and suggests new venues for prophylactic therapy

Intracranial invasion by Mucormycosis carries high mortality mostly related to arterial occlusion and ischemic necrosis. We report clinical, imaging and autopsy findings in an adult immunodeficiency syndrome (AIDS) patient with fungal infection extending from a tooth. We report a striking discordance between a restriction of fungal growth to the initial branches of the circle of Willis and extensive ischemic infarcts of deep brain structures. This lends to a suggestion of apparently lost opportunities for brain salvage and prompts a re‐assessment of clinical approaches to treat mucormycosis.
