We report the case of a 78-year-old female with an aneurysm of the V4 segment of the vertebral artery and a six-year follow-up without any surgical or endovascular treatment. The natural evolution of a small aneurysm into a giant aneurysm is rarely observed. We discuss the pathophysiology of the development and growth of such aneurysms through a review of the literature.

L-dopa 100 mg plus benserazide 25 mg versus placebo were given 3 times daily to 14 consecutive patients with dementia and rigidity. The treatment was crossed over to the alternative therapy after a 7-day period. Despite a mean 60% raise in CSF-HVA during L-dopa administration, no patient responded to the treatment. These data suggest that dementia-associated rigidity differs, at least, pharmacologically from parkinsonian rigidity.

A case of diffuse polioencephalitis associated with non-differentiated bronchial carcinoma is reported. Clinically the patient presented mental distrubance and an extra-pyramidal syndrome. Anatomopathological investigation revealed inflammation of the cerebral hemispheres and the brain stem. Similar involvement of others regions of the central nervous system has been reported in the literature, probably indicating various locations of a single nosological entity. A viral origin is probable but not yet established.
