ABSTRACT
Myoclonus can present itself in various distinct clinical contexts. The authors review the possible different types of myoclonus, as a single manifestation or included in a syndrome, based on a semiological and aetiological classification. Special emphasis is given to the group of progressive myoclonus epilepsies.

The authors present a clinical case of an intracranial dural arteriovenous malformation with clinical manifestations of a prefrontal syndrome, documented with its respective diagnostic tests, including imaging studies. A number of considerations are being enlarged upon, concerning possible pathophysiological mechanisms.

The authors describe a right hemiparesis and global aphasia, suddenly developed in a 33-Year-old woman, with a previous aphasia, 7 years ago, from which she recovered without sequels. They discuss the relationship between protein inhibitor of blood coagulation and arterial thrombosis, and make references to what has been published about it.

The authors describe a case of hereditary neuropathy with liability to pressure palsies (entrapment), and compare it to reports from literature. The main characteristics are: autosomal dominant inheritance, recurrent mononeuropathies (ulnar, median, peroneal, brachial plexus), and specific features at nerve biopsy. The sensory nerve reveals predominantly demyelinating alterations, having the remaining myelin fibres focal thickenings, the so called tomaculous, and shows numerous subperineural structures named Renaut Bodies. The EMG findings show a slowing of the nerve conduction velocities and an increase of distal latencies.
