title: Choroid plexus papilloma of the cerebello-pontine angle.
abstract: The clinical symptoms, neuroradiological findings and post-operative course is described in four patients affected with a choroid plexus papilloma of the cerebello-pontine angle. Clinical criteria (such as the early onset of signs and symptoms of raised intracranial pressure, and the early impairment of the auditory function) and the neuroradiological pictures (the lack of bone lesions, the tumour appearance as a hypodense mass on CT scan, which is well-enhanced after contrast injection) help the neurosurgeon to predict the surgical findings, but they cannot be considered as definite. The prognosis of such tumours is related more to the difficulties of the surgical intervention than to the peculiar properties of the growth.
