# Aortic Pseudoaneurysm Presenting As Pneumonia and Hemoptysis: An Atypical Presentation

## TL;DR

An 83-year-old woman with multiple health issues was initially diagnosed with pneumonia but later found to have a rare aortic pseudoaneurysm.

## Contribution

Highlights an atypical presentation of aortic pseudoaneurysm mimicking pneumonia and hemoptysis.

## Key findings

- Initial symptoms and imaging suggested community-acquired pneumonia and TB.
- Diagnosis was later revised to thoracic aortic pseudoaneurysm with surrounding hematoma.
- Hemoptysis worsened during hospitalization, prompting further investigation.

## Abstract

We report a case of an 83-year-old female patient, known to have multiple comorbidities, who presented to our hospital with pleuritic chest pain, productive cough with yellowish sputum and hemoptysis. Chest X-ray demonstrated left upper lobe infiltrate with high inflammatory markers. The patient was admitted as a case of community-acquired pneumonia with suspicion of pulmonary tuberculosis (TB). QuantiFERON-TB and Mycobacterium tuberculosis polymerase chain reaction (PCR) with septic workup, including blood and urine cultures, were sent; intravenous antibiotic was started empirically. During the patient’s hospital course, her hemoptysis worsened, and she was ultimately diagnosed with a thoracic aortic pseudoaneurysm with an associated surrounding hematoma.
