title: [A rare case of subarachnoideal pneumocephalus after ear douche therapy].
abstract: 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. On Jan. 6, 1984, sudden clouding of consciousness accompanying stiffness of the left arm occurred immediately after ear douche, and then he was transferred to our center. At admission, semicomatose, bilateral ocular deviation to the right, and left hemiparesis were observed. Plain skull X-ray films showed a retention of air in the frontal and temporal regions, while CT scan revealed air retention on the bilateral frontal region, bilateral temporal tip and suprasellar cistern. However, no abnormal findings were detected in the brain. Consciousness and hemiparesis recovered on the next day of hospitalization, however, the left hemispatial neglect still remained. 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)
