[A case of medial medullary infarction with persistent primitive hypoglossal artery].
No To Shinkei. 2002 Apr; 54(4):341-5.NT

Abstract

A 66-year-old woman was admitted to our hospital because of vomiting, dizziness and vertigo. Neurological examination on admission revealed only upbeat nystagmus without cranial nerve symptoms, paresis, cerebellar signs or sensory disturbances. Magnetic resonance(MR) images demonstrated a new T 2 high intensity and T 1 iso-intensity signal lesion in the right upper medial medulla. This medial medullary infarction caused central vestibular dysfunction. MR angiography and digital subtraction angiography demonstrated a persistent primitive hypoglossal artery (PPHA) originating from the right internal carotid artery to the vertebrobasilar artery associated with the stenosis of the right internal carotid artery at the level of the cervical bifurcation. This is the first report of medullary infarction with persistent carotid-basilar anastomosis. We suspected this medullary infarction was caused by artery to artery embolism in the branch of the right vertebral artery through the PPHA distal originated from the stenosis of the right internal carotid artery.
