Pseudotumoral Presentation of Cerebral Amyloid-Beta Angiopathy: Case Report and Review of Literature.

Objective: Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare and potentially treatable encephalopathy that usually affects people older than 50 years old and has an acute or subacute clinical presentation characterized by rapidly evolving cognitive decline, focal deficits and seizures. In a small subset of patients the disease can adopt a pseudotumoral form in the neuroimages that represents a very difficult diagnostic challenge.

Methods: Here in we report a patient with a tumour-like presentation of histopathologically confirmed CAA-RI.

Ischemic stroke of the "hand knob area": A case series and literature review.

Isolated hand paresis may reflect an infarction of the "hand knob area", which represents less than 1% of all ischemic strokes. In this type of stroke, a potential source of embolism is often identified. There are no large case series regarding this topic in Latin America.

Convexity Subarachnoid Hemorrhage Secondary to Adalidumab in a Patient with Ulcerative Colitis.

The TNF-α antagonists are the drugs used for the treatment of ulcerative colitis (UC). Nontraumatic convexity subarachnoid hemorrhage is an infrequent nonaneurysmal subtype of subarachnoid bleeding caused mainly by reversible cerebral vasoconstriction syndrome (RCVS), cerebral amyloid angiopathy, and posterior reversible encephalopathy syndrome (PRES). We present a 26-year-old female patient with a diagnosis of UC taking Adalimumab.

Impact of Infarct Size on Blood Pressure in Young Patients with Acute Stroke.

Background: Hypertension can be found in up to 80% of patients with acute stroke. Many factors have been related to this phenomenon such as age, history of hypertension, and stroke severity. The aim of our study was to determine the relationship between infarct volume and blood pressure, at admission, in young patients with acute ischemic stroke.

Convexity subarachnoid hemorrhage: clinical features and etiology of an Argentinian cohort.

Unlabelled: Nontraumatic convexity subarachnoid hemorrhage is an increasingly recognized subtype of subarachnoid bleeding.

Objective: Our aim was to describe the etiology and clinical features of a cohort of patients with convexity subarachnoid hemorrhage.

Methods: We retrospectively analyzed all cases of convexity subarachnoid hemorrhage admitted to our hospital between January 2012 and April 2017.

Blood pressure evolution in young patients with acute ischemic stroke: a new model for understanding the natural course of spontaneous hypertension?

Background: Approximately 80% of patients suffering an acute ischemic stroke develop transient hypertension. The physiopathological mechanism remains unclear. Due to the lack of vascular risk factors, young adults could be a useful model for understanding blood pressure (BP) evolution in this setting.
