Crossed Pain and Temperature Sensation Disturbance With Peripheral Facial Palsy Due to a Localized Lateral Inferior Pontine Infarction

Abstract

A 47-year-old man with dyslipidemia abruptly developed pain and temperature sensation disturbance on the left-sided face and right-sided body and extremities, and left-sided peripheral facial palsy. There were not any other neurological symptoms. Cranial magnetic resonance imaging demonstrated a localized infarct lesion in the left lateral inferior pons. The left anterior inferior cerebellar artery (AICA) was demonstrated by magnetic resonance angiography. Consequently, infarction of the left caudomedial branch of AICA might involve spinothalamic tract, spinal trigeminal nucleus and facial nerve. Here, we emphasize that combination of crossed pain and temperature sensation disturbance with peripheral facial palsy is an indicating sign of a localized lateral inferior pontine lesion.
