Abrupt onset of disturbed vigilance, bilateral third nerve palsy and masturbating behaviour: a rare presentation of stroke.

The clinical presentation of stroke usually includes sensory-motor impairment, cranial nerve palsies, or cognitive dysfunction. Disorders in behaviour are less frequently seen. The case of a patient with a very disturbing presentation, which included a disturbance in vigilance, bilateral third nerve palsy and masturbating behaviour, is presented. The topography of the lesions and its implications on the deficits observed are discussed.
