Infected Emphysematous Bullae of the Lung: A Diagnostic Challenge

TL;DR

A rare lung condition called infected emphysematous bullae is challenging to diagnose but can be managed with proper antimicrobial treatment.

Contribution

This paper presents a case study highlighting the diagnostic and management challenges of infected emphysematous bullae.

Findings

Imaging features included large thick-walled cavities with air-fluid levels.

MRCoNS was identified as the causative organism through microbiological analysis.

Antimicrobial therapy with doxycycline and linezolid led to a positive patient response.

Abstract

Infected emphysematous bullae of the lung present a diagnostic challenge due to their rarity and diverse clinical manifestations. We report the case of a 52-year-old female with chronic respiratory symptoms, including breathlessness and dry cough, persisting for six months. Imaging studies revealed characteristic features of infected emphysematous bullae, including large thick-walled cavities with air-fluid levels and associated parenchymal compression. Biomass exposure history and microbiological analysis, which isolated methicillin-resistant coagulase-negative Staphylococcus (MRCoNS), further supported the diagnosis. The patient responded well to antimicrobial therapy with doxycycline and linezolid. This case underscores the importance of considering environmental factors and multidisciplinary collaboration in managing complex respiratory conditions. Further research is warranted to elucidate optimal management strategies for infected emphysematous bullae of the lung.
