# Successful Intrasaccular Microcoil Embolization of a Lower Segment Pulmonary Artery Aneurysm in a Patient With Behcet’s Disease

## TL;DR

A rare case of a pulmonary artery aneurysm in a Behcet's disease patient was successfully treated with microcoil embolization and immunosuppressive drugs.

## Contribution

Demonstrates successful treatment of a life-threatening pulmonary artery aneurysm in Behcet's disease using microcoil embolization and immunosuppressive therapy.

## Key findings

- Microcoil embolization effectively managed a lower segment pulmonary artery aneurysm in a Behcet's disease patient.
- The patient achieved stable remission without complications after treatment with embolization and immunosuppressive medications.

## Abstract

Behcet's disease (BD) is an uncommon, long-term inflammatory condition characterized by recurring ulcers in the mouth and genital area, uveitis, and various systemic issues. One of the particularly rare but severe complications of this disease is the formation of pulmonary artery aneurysms (PAAs). Although these aneurysms are uncommon, they can lead to dangerous pulmonary hemorrhages (PHs), which are often fatal, requiring prompt diagnosis and intervention.

We present a case of lower segment PAA in an 18-year-old patient with recently diagnosed BD, presenting with life-threatening PH and managed successfully with microcoil embolization of the aneurysm and immunosuppressive (IS) medications, achieving stable remission without complications.
