INFANTILE CEREBRAL PALSY OF HEMIPLEGIC TYPE

Abstract
The authors refer to the case of a man with a right hemiplegia and absence of skilled movements on the right side dating from birth, who died at the age of 75 yrs. of acute myocardial failure and bronchopneumonia. The left sensorimotor area was obliterated by a developmental agenesis with local microgyria. Only area 6 and part of area 4s remained. The left pyramidal tract was almost wholly lacking. The left spinothalamic tract was markedly atrophic (agenetic) and the left medial lemniscus was about 1/2 the normal size. There was atrophy of the thalamus and there were changes in the fibers of the internal capsule. The absence of the pyramidal tract made the other corticopontile and corticonigral tracts clearly demonstrable. The extrapyramidal structures and functions appeared to be wholly preserved. The principal clinical manifestation of the disorder was a hypotonic flaccid paralysis with loss of all skilled movements.
