Tuberk Toraks. 2011;59(4):369-73.
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.
一名30岁男性患者因胸部计算机断层扫描（CT）血管造影被诊断为肺血栓栓塞症，结果显示血栓完全阻塞左主肺动脉。该病变被评估为肿瘤性肿块。正电子发射断层扫描（PET）-CT显示肺动脉肿块处有病理摄取。由于肿瘤的位置，进行了左肺切除术。病理诊断为肺动脉肉瘤。该患者前来就诊是因为肺动脉肉瘤是非常罕见的肿瘤，可酷似肺血栓栓塞症。由于许多肺动脉肉瘤被误诊为肺血栓栓塞症，其真实患病率被低估。PET-CT可能有助于进行鉴别诊断。
