A 28-YEAR-OLD MAN with long-standing asthma was admitted to the hospital in status asthmaticus. Necessary treatment modalities included high-dose methylprednisolone, sedation, and succinylcholine-induced paralysis for intubation. Pulmonary infiltrates were noted on a chest radiograph, and the patient could not be weaned from ventilation use. Decreasing consciousness was observed, and the results of a computed tomographic scan of the head showed ring-enhancing lesions in the right frontal and left parietal cerebral lobes. After rapid neurologic decline, the patient died.
