Hemorrhagic venous infarct related to venous thrombosis in a 29-year-old woman who had two seizures after having 1 week of cough and fever and who received positive test results for COVID-19 in the emergency department. (a) Axial nonenhanced head CT image shows a left temporoparietal hemorrhagic venous infarct (arrows), with adjacent edema, mass effect, and minimal rightward midline shift. (b) Axial CT venogram shows absence of contrast material in the left sigmoid sinus (arrows), indicative of venous sinus thrombosis. (c) Three-dimensional maximum intensity projection image from MR venography shows thrombosis of the left transverse and sigmoid sinuses (solid arrows). Note that the right transverse sinus appears patent (dashed arrow). — Hemorrhagic venous infarct related to venous thrombosis in a 29-year-old woman who had two seizures after having 1 week of cough and fever and who received positive test results for COVID-19 in the emergency department.
