| Summary: | We present a rare case of primary pulmonary artery intimal sarcoma diagnosed after emergency admission for respiratory failure in an 80-year-old man. Tumor cells were obtained through minimally invasive pulmonary arterial catheter aspiration at a high-intensity magnetic resonance–diffusion-weighted imaging–highlighted site. Despite the patient's poor overall condition, right heart catheterization confirmed the diagnosis and murine double minute 2 positivity. Palliative care was implemented, and the patient died 13 days after admission. Our case underscores the importance of recognizing this sarcoma in pulmonary artery abnormalities, highlighting complementary roles of magnetic resonance–diffusion-weighted imaging in increasing prediagnostic probability and right heart catheterization in facilitating minimally invasive murine double minute 2 assessment. |
