An 84-year-old male patient with no known comorbidity was admitted to the emergency department with complaints of dyspnea and respiratory distress. The patient was referred to the COVID outpatient clinic, laboratory and radiology tests were performed. Thoracic CT scan of the patient showed large peripheral patchy ground glass densities observed in the lower lobes of both lungs. CT imaging findings were evaluated by an experienced radiologist and reported as COVID-19 pneumonia. The patient, who was self-isolated at home for 5 days, presented to the emergency department again on the fifth day with complaints of respiratory distress, fever, bruising with cough, and loss of peripheral pulse in the left lower extremity. Necessary tests were performed on the patient. An above-knee amputation was performed when a diagnosis of limb ischemic necrosis was made and no revascularization attempt was considered by the CVS department. This case study describes the coexistence of sudden lower extremity thrombosis and Covid-19 in our case without a known chronic disease.
