Abstract
Bilateral cerebral peduncular infarction (BCPI) is a very rare disorder among stroke patients. The main clinical manifestations in the previously reported BCPI case reports was associated with locked-in syndrome or persistent vegetative state. Here, we present a 51-year-old woman who had pseudobulbar palsy and quadriplegia. Magnetic resonance imaging showed an acute infarction in the middle areas of the cerebral peduncle with a unique ¡°Mickey Mouse ears¡± sign. Diffusion tensor imaging and tractography showed relatively preserved corticospinal tracts, but the corticobulbar tracts were not detected. Magnetic resonance angiography showed posterior cerebral artery and vertebrobasilar artery occlusion. Cerebral perfusion insufficiency due to stenosis or occlusion of the vertebrobasilar artery and its branches may lead to BCPI. The prognosis and clinical manifestations of BCPI are related to the extent of the infarction in the involved cerebral peduncle and whether other territories are involved. Isolated BCPI may present a severe pseudobulbar palsy with relatively preserved limb function depending on the involvement pattern.
