Abstract
It was reported that a man of 73 years old had his head injured by a traffic accident and 2 months later had his left VIth, Xth, and XIIth cranial nerve paralized. Whether the cranial traumatic sequelae developed into multiple cranial nerve paralysis or the paralysis was caused from multiple cranial neuritis which afterwards accidentallyaccompanied the head injury was discussd from the standpoint of clinical neurology and neuropathology. The discussions led to the conclusion that exact diagnosis must depend on the accumulation of future comparative studies of clinical and postmortem pathological findings on head-injured patients.
