Cerebral microhemorrhages in severe COVID-19 pneumonia.

ABSTRACT

Background: Cerebral microhemorrhages are a complication in patients with severe COVID-19 pneumonia. Case Description A 50-year-old woman presented to the hospital with shortness of breath due COVID-19 (SARS-CoV-2, alpha variant) pneumonia. Her hospital course was complicated by hypoxic respiratory failure requiring intubation and severe acute respiratory distress syndrome. She received a tracheostomy for ongoing ventilator support after prolonged intubation. Her mental status was notable for disorientation and severe agitation for which a magnetic resonance imaging (MRI) of the brain was obtained. MRI revealed numerous microhemorrhages predominantly at the gray-white matter junctions. Conclusion: Cerebral microhemorrhages in severe COVID-19 pneumonia are associated with critical illness, increased mortality, and worse functional outcome. The pathophysiology of cerebral microhemorrhages in COVID-19 is unknown.
