# Pulmonary Artery Sarcoma With Lung Metastasis

## TL;DR

A rare case of pulmonary artery sarcoma with lung metastasis was diagnosed in a 77-year-old woman using contrast-enhanced CT.

## Contribution

This case highlights the diagnostic value of contrast-enhanced CT in identifying pulmonary artery sarcoma.

## Key findings

- Contrast-enhanced CT revealed a contrast defect in the main pulmonary artery.
- The patient was diagnosed with pulmonary artery sarcoma based on imaging findings.

## Abstract

Pulmonary artery sarcoma is a rare disease that has been frequently misdiagnosed. A 77‐year‐old woman presented with palpitations and was found to have pulmonary hypertension. Contrast‐enhanced computed tomography showed a characteristic contrast defect occupying the entire lumen of the main pulmonary artery, leading to a diagnosis of pulmonary artery sarcoma.
