(A) In the thorax CT examination performed during her stay in the intensive care unit, there are widespread consolidations and ground-glass densities compatible with alveolar filling. (B) In addition, there are crazy paving appearances formed by interstitial lines.. CT: Computed tomography.

The findings on the chest computed tomography (CT) were compatible with acute COVID-19 infection (Fig. 1A, B), but nasopharyngeal swab SARS-CoV2 reverse transcription-polymerase chain reaction (RT PCR) test (Bio-Speedy  SARS-CoV-2N RT-qPCR Kit; sensitivity: 80%, specificity: 98%) was negative.
(A) Thoracoabdominal CT examination. Diffuse wall thickening and narrowing of the lumen are observed in the abdominal aorta on sagittal MR images. The origins of celiac and the superior mesenteric arteries are clearly narrowed. (B) On axial CT images, there is marked narrowing of the lumen secondary to all-around wall thickening at the origin of the left renal artery and the right renal artery (arrows). (C) There is irregular luminal narrowing secondary to circumferential wall thickening in the abdominal aorta (yellow dotted ring).. CT: Computed tomography.

Abdominal CT angiography revealed an increase in abdominal aortic wall thickness, narrowing of the lumen, and stenosis in bilateral renal arteries (Fig. 2A-C).
In the pulmonary CT angiography performed on the day of hemoptysis, ground-glass densities in the posterobasal region of the left lung lower lobe and filling defects secondary to wall thickening in the distal pulmonary arteries extending to this site are observed.. CT: Computed tomography.

Diffuse alveolar infiltrates and interlobar septal thickenings were detected on the CT, and there were no COVID-19-related findings in the lungs (Fig. 3).
