Micturition symptoms in frontal tumours.

In a series of 50 consecutive tumours involving the frontal lobes, seven cases (14%) were found who exhibited the syndrome, first described by Andrew and Nathan in 1964, of frequency of micturition, urgency, and incontinence causing distress to the patient. This suggests that this syndrome may occur rather more commonly than those authors had indicated. In 100 consecutive intracranial tumours, no instances were found with non-frontal tumours, indicating that the syndrome may be of localizing value.
