Multiple Kidney Infarctions Due to COVID-19 Infection in a Patient with Repeatedly Negative RT-PCR Tests-A Case Report.

Since the outbreak of novel coronavirus in 2019, SARS-CoV-2 has spread worldwide at an unexpected rate, becoming a major global health concern. Although respiratory tract infections represent typical clinical presentation, recently, numerous cases of acute arterial thrombosis and thromboembolic disease have been reported due to COVID-19 infection. Renal artery embolism is a condition that is easily missed due to its infrequent and nonspecific presentation. In this paper, we reported a case of a 63-year-old, previously healthy, male patient who has developed multiple right kidney infarctions due to COVID-19 infection without any respiratory or other typical clinical manifestations. Consecutive RT-PCR tests were negative and the diagnosis was set finally by serological screening. Our presentation has emphasized the necessity of clinical, laboratory, microbiological, and radiological integration in diagnostic approach to this novel and challenging disease with often unusual clinical presentations to avoid false negative discrimination.
