Medical Definition of Arytenoid swelling
1. Paired primordial elevations, on either side of the embryonic larynx, within which the arytenoid cartilages are formed. Brain swelling, a pathologic entity, localised or generalised, characterised by an increase in bulk of brain tissue, due to expansion of the intravascular (congestion) or extravascular (oedema) compartments that may coexist or may occur separately and be clinically indistinguishable; clinical manifestations depend on disturbed neuronal function due to local swelling, shifting of intracranial structures, and the effects of intracranial hypertension or circulatory disturbance.
