## TL;DR

This paper presents a rare case of pulmonary hypertension caused by a cardiac myxoma, highlighting the role of multi-modality imaging in diagnosis.

## Contribution

The paper introduces a rare case of myxoma embolism causing pulmonary hypertension, emphasizing the diagnostic value of multi-modality imaging.

## Key findings

- Cell proliferation from a right atrial myxoma caused artery aneurysms and pulmonary hypertension.
- Multi-modality imaging and dual-energy scanners were effective in diagnosing the condition.
- Only three similar cases have been reported in the literature.

## Abstract

We report an original case of pulmonary hypertension with artery aneurysms due to the cell proliferation of a right atrial myxoma with multi-modality imaging. Only three cases have been reported in the literature. The description of endoluminal cells proliferation in pulmonary arteries is rare on imaging, and this observation could be very useful in demonstrating not only the usefulness of multi-modality imaging, but also the combined performance of the dual-energy scanner.
