[Partial non-convulsive status epilepsy in multiple sclerosis].

This report describes the observations of two patients with a several years' history of multiple sclerosis who presented sudden neurologic impairment. The symptomatology was suggestive of a non-convulsive partial status epilepsy. The clinical presentation was a paroxysmal dysphasic phenomenon in the first case without any consciousness impairment, associated with slight right hemiparesis.

[Causes of paralysis of the hypoglossal nerve. Apropos of 32 cases].

Thirty-two consecutive cases of hypoglossal nerve palsy (excluding syringomyelia and amyotrophic lateral sclerosis) collected between 1971 and 1987 were reviewed. The XIIth nerve palsy was clinically isolated in 8 cases, associated with other cranial nerve palsies in 16 cases and with long tracts involvement in 8 cases. Seventeen cases were related to tumours.

[Cerebellar imitation synkineses].

Two patients with autosomal dominant pure cortical cerebellar atrophy, belonging to the same family, exhibited imitation synkineses of hands and feet when the contralateral extremity was moved. The phenomenon was observed particularly when alternate movements of one hand were performed, but it also existed when flexion-extension movements of one foot took place. The induced synkinetic movements were mainly observed on the right side in one patient and exclusively observed on the right side in the other one.

[Giant thrombosed aneurysm of the left vertebral artery developing in the fourth ventricle].

A case of giant, thrombosed, non haemorrhagic aneurysm of the distal portion of the left vertebral artery is reported. The patient came to medical attention with an acute cervical pain after a minimal cervical traumatism and a diagnosis of torticollis from rheumatologic cause was made. In fact, a few weeks before, he had suffered three episodes of right homonymous hemianopsia.
