Özet
Acquired pulmonary stenosis is very rare in adults and diagnosis requires a high index of suspicion. Malignant mediastinal masses may compress cardiac structures and great vessels.45- year-old female patient was admitted to the emergency department with dyspnea and chest pain. Arterial blood gas analysis revealed hypoxia and respiratory alkalosis (pH 7,51, pCO2 65 mmHg, pO2 65, HCO3 26 mEq/L, lactate 6 mmol/L).patient had decreased breath sounds in the right hemithorax, 2-3/6 apical systolic ejection murmur, pretibial edema, jugular venous pressure. Electrocardiogram revealed right axis deviation and sinus tachycardia. D-dimer value was 300 ng/ml. Thorax computed tomography angiography revealed no thrombus or dissection. CT revealed soft tissue mass compressing right pulmonary artery and right pleural effusion. External compression of pulmonary artery may clinically mimic pulmonary thromboembolism. Low D-dimer levels may rule out pulmonary thromboembolism. External pulmonary artery compressions may not increase D-dimer levels. Tomographic imaging should be preferred in patients with unexplained dyspnea.
