Description
Christoph Matthias and co-authors report a case of a rare artery tumor diagnosed through a vein-based biopsy, in this 2026 paper. Tumors of the pulmonary artery are rare and often pass for blood clots, which delays care. A middle-aged woman with fading exercise tolerance had a growing mass near the lung root that nearly blocked her left pulmonary artery. Standard biopsy routes were judged too risky.
The team threaded a catheter to the mass and sampled tissue under ultrasound guidance from inside the heart. Sampling succeeded with no complications. Lab and gene tests showed a malignant tumor with a marker gene amplification, matching an intimal sarcoma of the artery. The authors present the guided biopsy as a safe option when usual routes are too dangerous.
