Fig. 4 — a. NCCT of the head in a COVID-19 patient demonstrates numerous punctate foci of hyperdensity (arrowheads), consistent with petechial hemorrhage. b Axial susceptibility-weighted image (SWI) from a brain MRI of the same patient demonstrates extensive foci of hypointensity, consistent with susceptibility artifact from hemorrhage. Findings were consistent with thrombotic microangiopathy. Reference: Nicholson P, Alshafai L, Krings T. Neuroimaging Findings in Patients with COVID-19.
