Raises awareness for sarcoma in unexplained pulmonary artery occlusion; leaves open optimal imaging protocols for rare cases.
Figure 1.Chest radiograph revealed a right hilar mass (A), which on contrast-enhanced computed tomography was found to be a large intravascular tumor occluding the right main pulmonary artery with extension into the lumen of the main and left pulmonary arteries (B).A dynamic magnetic resonance image demonstrated the tumor within the main pulmonary artery but without mural invasion (C).Tumor within the main pulmonary artery as visualized intraoperatively after pulmonary arteriotomy (D).Gross histology demonstrated involvement of superior, middle, and inferior lobes (E) with tumor completely occluding the right pulmonary artery lumen (F).
