# Complicated traumatic pulmonary pseudocyst: a case report

## TL;DR

A rare case of a complicated lung cyst caused by chest trauma is reported, which resolved on its own with proper diagnosis and monitoring.

## Contribution

This paper presents a unique case of a complicated traumatic pulmonary pseudocyst that resolved without intervention.

## Key findings

- The patient's lesion resolved completely over six months without treatment.
- Accurate diagnosis is crucial to differentiate TPP from other lung conditions.
- Conservative management with follow-up leads to a reasonable prognosis in such cases.

## Abstract

A traumatic pulmonary pseudocyst (TPP) is an uncommon lung lesion that can occur due to blunt chest trauma. This condition is usually harmless and doesn't require medical treatment, but in rare cases, it is complicated by rupture of the lesion and hemothorax. We present the case of a 43-year-old man who fell from a height and suffered chest trauma. Imaging revealed a mass-like lesion and hemothorax, but after ruling out other diagnoses, he was diagnosed with complicated traumatic pulmonary pseudocyst. Over six months, the mass-like lesion shrank and disappeared entirely without any remaining scars. Proper diagnosis and differentiation from other lung lesions are essential in cases of TPP. With conservative management and regular follow-up, the prognosis is generally reasonable.
