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.
