Multifocal, linear hyperdensities suggestive for hemorrhages, involving both the cortex and the adjacent subarachnoid space, were evident in seven out of nine cases (30% of all the patients), with very subtle superficial enhancement after contrast administration (Fig. 1). The remaining two cases (8.6%) showed cortical–subcortical areas of hypoattenuation with sulcal effacement, consistent with acute–subacute ischemia, with hemorrhagic transformation in one case (4.3%).\nFig. 1 Plain (left column) and contrast-enhanced brain CT scans (right column) in two patients with severe COVID-19 infection. a–f: Male, 62 years old, with multifocal, linear hyperdensities
