Clinical Report: Bilateral Cavitary Lung Lesions in a Patient with Pulmonary Brucellosis
Overview
This case study presents a 76-year-old male with bilateral cavitary lung lesions due to pulmonary brucellosis, highlighting the importance of considering this diagnosis in patients with livestock exposure. The patient showed significant improvement following a prolonged antibiotic regimen.
Background
Pulmonary brucellosis is a rare manifestation of brucellosis, often misdiagnosed due to its non-specific symptoms and imaging findings. The condition is particularly significant in regions with high livestock exposure, where brucellosis is endemic. Understanding its clinical presentation and diagnostic challenges is crucial for timely management.

Parameter
Details
Patient Age
76 years
Symptoms Duration
2 years
Initial Treatment Duration
3 days
Prolonged Treatment Duration
140 days
Outcome
Marked symptomatic improvement
Key Findings
Multiple cavitary lung lesions in pulmonary brucellosis are exceptionally rare.
Chest CT revealed irregular mass-like opacities and multiple nodules with cavitation.
Metagenomic next-generation sequencing confirmed the presence of Brucella species.
Prolonged combination antibiotic therapy led to significant clinical and radiological improvement.
Consideration of pulmonary brucellosis is essential in differential diagnoses for cavitary lung lesions in patients with livestock exposure.
Clinical Implications
Clinicians should maintain a high index of suspicion for pulmonary brucellosis in patients with relevant exposure history presenting with cavitary lung lesions. Early diagnosis and appropriate antibiotic therapy are critical for improving patient outcomes.
Conclusion
This case underscores the rarity of pulmonary brucellosis presenting as cavitary lung lesions and the effectiveness of prolonged antibiotic treatment in achieving clinical improvement.
Journal pre-proof study of more than 38,000 patients found timely antibiotics and indicated fluid resuscitation were associated with increased odds of returning home
