ABSTRACT
A case of loss of psychic self-activation (LPSA) and serious amnesia, followed for a period of ten years, is reported. MRI examination documents a selective bilateral lesion of the globus pallidus. This clinical picture, which evokes a cognitive and behavioral deficit of frontal lobe lesions, is attributed to a dysfunction of the frontal cortical area as a result of the breakdown of the frontostriatal circuits.

A series of 100 consecutive new outpatients attending the neuroradiology service for a cranial CT scan between 1 October and 24 December 1984 were analyzed. On the day of the investigation each patient was examined by a neurologist, who gave his opinion on the value of a CT scan. The neurologist's ratings were then compared with the CT reports. More than 2/3 of the requests for CT were useless and could have been avoided by thorough clinical evaluation of the patients and full awareness of what CT scanning can contribute to diagnosis and treatment.

The AA relate a case of a complex malformation of the AICA characterized by aneurysm of the internal auditory artery developed inside the internal acoustic channel associated with an angioma fed by the cerebellar branch of the same artery. During a long period with dizziness, tinnitus, headache in the occipital region, mild sensoneural retrocochlear hearing loss a subarachnoid hemorrhage occurred. The vascular malformations were visualized by a vertebral angiography and the axial projection resulted to be the most important clue. The AA report the case for its rarity and emphasize the vascular origin of certain unexplained kinds of vestibular syndromes in young patients.
