COVID-19 affects other organs in addition to the respiratory system. Renal cortical necrosis is a severe kidney injury due to decreased renal arterial perfusion induced by vascular spasm, microvascular injury and endovascular thrombosis. Acute kidney injury is a common finding in COVID-19; however, renal cortical necrosis is rare. To the best of our knowledge, only one case of renal cortical necrosis has been reported in the literature.
