Successful basilar artery dilatation in pure bilateral cerebral peduncular infarctions using balloon angioplasty

Abstract

Highlights An extremely rare case of bilateral cerebral peduncular infarctions (BCPI) is reported. The detection of the pure Mickey Mouse ears sign on MRI is an indicator of a need for reperfusion therapy. Severe stenosis of the basilar artery (BA) and a poor collateral supply from both posterior cerebral arteries were seen. Balloon angioplasty for the BA stenosis ameliorated the stenosis and produced a favorable outcome.
