# A Rare Case of Allergic Bronchopulmonary Aspergillosis With Endobronchial Aspergilloma Causing Total Lung Collapse

## TL;DR

A rare case shows how a fungal infection caused a lung to collapse and was successfully treated with a combination of procedures and medications.

## Contribution

This paper presents a rare clinical case linking allergic bronchopulmonary aspergillosis with endobronchial aspergilloma leading to lung collapse.

## Key findings

- A 70-year-old man's lung collapse was caused by a fungal ball in the bronchus.
- Treatment with bronchoscopy, corticosteroids, and voriconazole led to full recovery.
- The case emphasizes the need to consider fungal causes in atypical lung collapse presentations.

## Abstract

We present a rare case of allergic bronchopulmonary aspergillosis (ABPA) with endobronchial aspergilloma in a 70-year-old man who presented with acute total collapse of the left lung. Initial imaging raised concern for malignancy, but bronchoscopy revealed a fungal ball obstructing the left main bronchus. Serological markers confirmed ABPA. Treatment with bronchoscopy-guided clearance, oral corticosteroids, and voriconazole led to complete clinical and radiological recovery. This case highlights the importance of considering fungal aetiologies in atypical presentations of lung collapse.
