[An autopsy case of fungal (Mucor) cerebral aneurysm].

An autopsy of rupture of Mucor cerebral aneurysm, not diagnosed during the patient's life, was experienced. A 63-year-old female was admitted to our hospital with the chief complaint of disturbance of consciousness and high fever. Her past histories were diabetes mellitus, liver cirrhosis and nasal sinusitis. The remarkable findings on admission were moderate inflammatory data, high blood sugar level in serum and ascites. Brain CT film revealed a non-enhanced low-density area in the frontal region. The cerebrospinal fluid showed bloody color and white blood cell counts were 3300/microliter (mostly neutrophils). Under our suspected of bacterial encephalomeningitis, intravenous cefotaxime and ampicillin therapy was started immediately. Cultures of cerebrospinal fluid for bacteria were negative. The disturbance of her consciousness gradually improved under general treatment. However, her conscious level suddenly became a coma on the 6th hospital day and she died on the 9th hospital day. An autopsy revealed Mucor at the site of the rupture of the cerebral aneurysm.
