Pulmonary artery sarcoma mimicking pulmonary thromboembolism.
A 30 years old male patient was referred to our hospital with a diagnosis of pulmonary thromboembolism due to thorax-computerized tomography (CT) angiography, revealing a thrombus totally occluding left main pulmonary artery. The lesion was evaluated as tumoural mass. Positron emission tomography (PET)-CT revealed pathologic uptake at pulmonary artery mass. Due to localization of tumour, left pneumonectomy was performed. The pathological diagnosis revealed to be pulmonary artery sarcoma. The patient was presented because pulmonary artery sarcomas are very rare tumors and can mimick pulmonary thromboembolism. The true prevalence is underestimated as many pulmonary artery sarcomas are misdiagnosed as pulmonary thromboembolism. PET-CT may help to make a differential diagnosis.
