Biopsy-Proven Amyloid-Beta Related Angiitis with Unusual Presentation and Long-Term Follow-Up.

Amyloid-beta related angiitis (ABRA) is a rare central nervous system inflammatory and vasculitic process. It is seen in patients with cerebral amyloid angiopathy (CAA) and thought to be mediated by an autoimmune reaction against cerebrovascular β-amyloid. We describe the case of a patient with ABRA with clinical information and brain imaging over a 10-year period.

A Case of Salicylate Toxicity Presenting with Acute Focal Neurologic Deficit in a 61-Year-Old Woman with a History of Stroke.

BACKGROUND Over-the-counter medications that contain aspirin are widely used, and patients generally regard them as safe. However, the side effects of salicylate toxicity can be severe, and delay in the diagnosis may increase the risk of mortality. Neurologic symptoms are a common presenting feature of salicylate toxicity in the elderly, and their recognition may allow earlier diagnosis.

Effects of Age, Gender and Hemispheric Location on T2 Hypointensity in the Pulvinar at 3T.

Pulvinar signal intensity decrease on T2-weighted images has been reported in some neurological abnormalities. We aimed to define the normal T2 signal hypointensity pattern present in the pulvinar to avoid erroneous radiological interpretation. One hundred and forty-two subjects (54 men and 88 women; age range 9-91 years) with unremarkable brain 3T MR findings were enrolled.

Selective infarction of the anterior genu fornices associated with giant cell arteritis.

We report a middle-aged woman presenting with acute confusion and anterograde amnesia. Magnetic resonance imaging revealed an acute infarction of the anterior genu fornices. Evaluation of an elevated erythrocyte sedimentation rate led to the diagnosis of giant cell arteritis (GCA).
