Abstract

A patient with contralateral monoparesis of the leg due to subarachnoid hemorrhage (SAH) from an aneurysm of the first posterior inferior cerebellar artery (PICA) segment is reported. The monoparesis may well be associated with the close anatomical relationships between the site of the aneurysm and the PICA blood supply of the corticospinal fibers to the contralateral leg.
