No detailed reports on pneumocephalus caused by any factors other than head trauma, and their courses accompanied with this disease have been so far available. We recently experienced a case of pneumocephalus complicated with severe clouding of consciousness, ocular deviation, and unilateral spatial neglect with the results being reported hereinafter. A 54-year-old man had often received ear douche therapy due to chronic sinusitis and tubal obstruction about 3 years before without any history of head trauma. ⋯ This symptom was still observed on the 3rd day but disappeared by the 4th day of hospitalization. For clarifying its cause, cerebral angiography, CT scan and electroencephalography were then performed. CT scan revealed no anomalies in the brain, while cerebral angiography showed a cerebral circulation pattern in favor of the right internal carotid artery.(ABSTRACT TRUNCATED AT 250 WORDS)
