Magnetic Resonance Imaging in Two Cases of Pontine Infarction with Vertigo

Abstract

Otoneurological examination of two patients with central vertigo showed brainstem disorders, but no abnormal areas were seen in CT scans. Magnetic resonance imaging (MRI) clearly showed abnormal signal intensity regions in the pons. MRI is more sensitive than CT in demonstrating infarctions of the brain, especially those in the brainstem and cerebellum, because it is less influenced by bone artifacts and has high contrast resolving ability. MRI is useful for the definite diagnosis of central vertigo.
