Right MCA Infarction (teaching)

Discussion:

This case shows the acute and sub-acute signs of infarction.

The symptoms described (contralateral hemiparesis) are typical for MCA strokes but can be mimicked by other diagnoses, so a good and timely clinical history, examination and imaging are important.  Other symptoms that can occur with MCA strokes include:

  • contralateral hemisensory loss
  • hemianopia
  • aphasia: if dominant hemisphere
    • expressive in anterior MCA territory infarction (Broca's area),
    • receptive in posterior MCA stroke (Wernicke's area),
    • or global with extensive infarction
  • neglect: non-dominant hemisphere
