Abstract
There is no information on renal vein thrombosis induced by COVID-19 infection in a neonate. Few cases of renal vein thrombosis caused by COVID-19 infection have been reported in predominantly adult patients. On day 25 after birth, a newborn whose mother was infected with COVID-19 had renal vein thrombosis. We believed that our patient's renal vein thrombosis was caused by postnatal transmission of the COVID-19 infection that the mother had acquired during birth. The clinical and radiologic findings of these unusual renal complications in a neonate, as well as treatment options, are presented.
