Unusual combination of cerebral dysplasias. Report of two cases.

Two types of a rare combination of cerebral malformations originating from parenchymal and/or vascular developmental disorders are described. In the first case, there is a coincidence of aneurysm, AVM, persistent trigeminal artery and arachnoid cyst. In the second case a giant infratentorial aneurysm, dural AVM and haemangioma of the neck are combined.

Peripheral neuropathy after administration of tetanus toxoid.

A reversible paresis of several muscles of the right arm was observed in a 20-year-old female, 3 weeks after the intragluteal injection of tetanus toxoid and 6--7 weeks after multiple injuries. The EMG findings indicated a transitory conduction block of nerve fibers to the deltoid and pectoralis muscles and a more severe axonal-demyelinating lesion of fibers to the biceps muscle. The cause of the palsy was probably a reaction to the administration of tetanus toxoid; other possible causes are discussed.
