Eight-and-a-half syndrome.

Eight-and-a-half syndrome is a clinical entity comprised of one-and-a-half syndrome with ipsilateral facial palsy. We report a case who presented with this constellation of findings with diffusion weighted images (DWI) and apparent diffusion coefficient (ADC) changes corresponding to the anatomical correlate in the dorsal pontine tegmentum.

MRI changes in thrombotic microangiopathy secondary to malignant hypertension.

Thrombotic microangiopathy with thrombocytopenia and intravascular hemolysis are characteristic of three disorders: malignant hypertension (MH), disseminated intravascular coagulation (DIC), and thrombocytopenic thrombotic purpura (TTP). We describe a patient with thrombotic microangiopathy secondary to malignant hypertension that caused extensive bilateral cortical ischemic infarction.

Subclavian artery dissection and triple infarction of the nervous system.

Background: Subclavian artery dissection is a rare entity. It is usually associated with anomalous aortic vasculature. Only with trauma or catheterization procedures is subclavian artery dissection with normal aortic vasculature reported.
