# Radiotherapy for Lung Cancer: An Unrecognized Cause of Lung Torsion

## TL;DR

A 73-year-old woman developed lung torsion after radiotherapy for lung cancer, highlighting a rare and previously unreported complication.

## Contribution

This is the first reported case of lung torsion following radiotherapy, suggesting a novel clinical association.

## Key findings

- The patient experienced lung torsion after successful radiotherapy for lung adenocarcinoma.
- The case was managed conservatively due to the absence of clinical symptoms.
- The mechanism linking radiotherapy to lung torsion remains unclear and requires further investigation.

## Abstract

Lung torsion is an exceptional occurrence, usually requiring urgent surgery because of vascular compromise. Because of the rarity and non-specific symptoms, it often requires clinicians to have a high degree of suspicion to make an early diagnosis of lung torsion. Here we present a unique case of lung torsion. The patient was a 73-year-old lady who was diagnosed with adenocarcinoma of the lung. She was treated with radiotherapy, which resulted in complete remission. However, her follow-up imaging showed torsion of the right lung. Given her lack of clinical symptoms, she was managed conservatively. This is a unique case and possibly the first reported case of lung torsion following radiotherapy. The exact mechanism through which radiotherapy causes lung torsion remains unclear and may be addressed by future research.
