Brachial artery thrombosis and renal infarct in a 51-year-old man who presented to the emergency department with acute left upper extremity pain and numbness. The patient had a 2-week history of cough and fever and was confirmed to be COVID-19 positive. (a) Coronal left upper extremity CT angiographic image shows an abrupt segmental occlusion (arrow) of the distal left brachial artery, indicative of peripheral arterial thromboembolization. The left subclavian and axillary arteries were otherwise unremarkable, with good opacification of the arteries. (b) Coronal three-dimensional maximum intensity projection shows abrupt cutoff (arrow) of the left brachial artery. (c, d) Axial chest CT angiographic images show the typical appearance of lung changes in COVID-19 pneumonia (arrows in c). Note the incidentally found sharp well-defined area of nonenhancement in the partially imaged upper pole of the right kidney, a finding indicative of a renal infarct (arrows in d). — Brachial artery thrombosis and renal infarct in a 51-year-old man who presented to the emergency department with acute left upper extremity pain and numbness.
