Abstract
Pulmonary artery (PA) sarcoma is an extremely rare malignant tumor of pulmonary artery. It is often misdiagnosed as pulmonary thromboembolism (PTE) because of its clinical and imaging features which are quite similar to PTE. Multimodality diagnostic imaging and recognition of specific imaging characteristics with appropriate clinical suspicion are required to make correct diagnosis. In this report, we present a case of PA sarcoma with imaging and clinical features as well as emphasize significance of using multimodality imaging.
Highlights
Pulmonary artery (PA) sarcoma is a rare tumor originating from mesenchymal cells of pulmonary artery
We reported a case of PA sarcoma with characteristic computed tomography pulmonary angiography (CTPA) features and emphasize differential diagnosis
CTPA features of PA sarcoma are similar to pulmonary thromboembolism (PTE) with respect to intraluminal filling defects, some subtle differences can raise suspicion of PA sarcoma
Summary
Pulmonary artery (PA) sarcoma is a rare tumor originating from mesenchymal cells of pulmonary artery. Main manifestation of PA sarcoma on computed tomography pulmonary angiography (CTPA) is filling defect, which mimics PTE. Due to its nonspecific clinical and imaging features, early diagnosis is tough preoperatively [1]. It is crucial to differentiate PA sarcoma from PTE based on imaging and clinical features.
