Aspergillosis of the nervous system.
Cerebral aspergillosis currently occurs most frequently with disseminated aspergillosis in immunocompromised hosts. Twelve patients with cerebral aspergillosis in this setting were seen over 10 years. Underlying illnesses were renal transplantation in six cases and one case each of subacute hepatic necrosis, head trauma, glioblastoma, microglioma, and esthesioneuroblastoma. All patients were receiving high dose steroid therapy except one who had ectopic ACTH syndrome. Eleven patients were receiving broad spectrum antibiotics. All patients were febrile and developed progressive pulmonary infiltrates preceding or coincident with neurologic symptoms. Sudden onset of neurologic deficits or seizures occurred in nine of 11 clinically analyzable cases. Brainstem or cerebellar signs and symptoms were a presenting feature in three cases and were eventually seen in five cases. Cranial computerized tomography in four cases showed low absorption areas with minimal enhancement and little mass effect. Neurologic deterioration was rapid with nine of 11 patients dying within 6 days of onset. Neuropathologic examination showed multiple abscess formation in 11 cases and prominent blood vessel invasion in all cases. The sudden onset of stroke-like deficits and brainstem findings in a febrile immunocompromised host with pulmonary infiltrates suggests the diagnosis of cerebral aspergillosis. Two cases of aspergillus meningitis were also seen, one postoperatively.
