Show the Anatomy                                                                                Oultine the Infarct

Pontine Infarction: (Left) T2-weighted axial MRI; (Right) Flair axial MRI. Note the bright signal in the right pons. This infarct is in the distribution of one perforating branch of the basilar artery. This lesion is usually caused by the occlusion of one perforating basilar branch, due to lipohyalinosis, which occurs as a result of aging, diabetes and hypertension. Occasionally these lesions are associated with intrinsic disease of the basilar artery or an embolus to the basilar artery. Note the wide open basilar artery in this case (flow void on the ventral pons).
