While COVID-19 pandemic has become an enormous and devastating pandemic for today's world, studies on the morbidity of the disease mainly show the disease's progress with pneumonia and thromboembolic pathologies. In this disease with a predisposition to thromboembolism, findings of nontraumatic focused hemorrhages are unexpected. As spontaneous retroperitoneal hematoma is a serious condition with the absence of symptoms, creating a challenge for diagnosis, it should also be considered in COVID-19 which is thought to be predisposed to thromboembolism. Here, a 47-year-old woman with COVID-19 pneumonia diagnosis (diagnosed by computed tomography (CT) scan and approved by nasopharyngeal swab test) is presented with spontaneous retroperitoneal hematoma, and its management is reported. This case highlights the importance of considering both thromboembolic events and bleeding in cases with COVID-19 positivity. The balance between two sides of clotting mechanisms needs to be understood with novel research.
