Primary pulmonary artery sarcoma (PAS) is a malignant neoplasm of the pulmonary vascular system originating from the intima, with clinical and imaging manifestations similar to those of pulmonary thromboembolism (PTE), and is often misdiagnosed. Spectral CT and PET/CT can clearly show the extent and metastasis of PAS and are valuable in visualizing adjacent structures such as lungs, bronchi, and mediastinum, providing a strong imaging basis for the diagnosis and differentiation of PAS, allowing treatment monitoring and follow-up.
原发性肺动脉肉瘤（PAS）是一种起源于内膜的肺血管系统恶性肿瘤，其临床和影像学表现与肺血栓栓塞症（PTE）相似，常被误诊。光谱CT和PET/CT能够清晰显示PAS的范围和转移情况，对于观察肺、支气管和纵隔等邻近结构具有重要价值，为PAS的诊断和鉴别诊断提供了有力的影像学依据，有助于治疗监测和随访。
