# Massive Hemoptysis Secondary to Rasmussen’s Aneurysm in a Patient With Active Pulmonary Tuberculosis: A Case Report

## TL;DR

A man with tuberculosis and diabetes had life-threatening lung bleeding due to a rare aneurysm, which was successfully treated with emergency intervention.

## Contribution

This case highlights the critical need for prompt diagnosis and treatment of Rasmussen’s aneurysm in tuberculosis patients.

## Key findings

- The patient had bilateral cavitary tuberculosis with a ruptured Rasmussen’s aneurysm.
- Endovascular embolization successfully stopped the bleeding and saved the patient’s life.

## Abstract

Rasmussen’s aneurysm is a rare but potentially deadly pseudoaneurysm of a pulmonary arterial branch adjacent to a tuberculous cavity. This report describes the case of a 38-year-old Bangladeshi man with uncontrolled type 2 diabetes who presented with sudden massive hemoptysis following six months of cough, weight loss, fever, and pleuritic chest pain. Imaging showed bilateral cavitary pulmonary tuberculosis with a pseudoaneurysm of the left lower-lobe pulmonary artery, consistent with a ruptured Rasmussen’s aneurysm. Urgent endovascular embolization achieved complete hemostasis. This case exemplifies the paramount importance of timely recognition and prompt therapeutic intervention in reducing mortality arising from tuberculosis-associated pulmonary hemorrhage.
