Microbleed patterns in critical illness and COVID-19.

Background: Cerebral microbleeds are increasingly reported in critical ill patients with respiratory failure in need of mechanical ventilation and/or extracorporeal membrane oxygenation (ECMO). Typically, these critical illness-associated microbleeds involve the juxtacortical white matter and corpus callosum. Recently, this pattern was reported in patients with respiratory failure, suffering from COVID-19.

Delayed cerebral thrombosis complicating bacterial meningitis.

Background: Delayed cerebral thrombosis has been described as a potential cause of cerebrovascular complications in patients with bacterial meningitis. We report a case of delayed cerebral thrombosis in a 63-year-old woman admitted for pneumococcal meningitis. Initially, there was a good clinical evolution under treatment with steroids and antibiotics.

Stroke due to non-bacterial thrombotic endocarditis as initial presentation of breast invasive ductal carcinoma.

We present a case of a 71-year-old woman with recurrent stroke episodes due to non-bacterial thrombotic endocarditis (NBTE) leading to the diagnosis of an early-stage breast carcinoma. NBTE is associated with a variety of inflammatory states, including malignancy. NBTE presents itself with systemic embolization, mostly stroke.
