Brucellosis Presenting as Cavitary Pneumonia with Multiple Pulmonary Nodules: A Rare Presentation

ABSTRACT: Brucellosis is a common zoonotic disease, yet pulmonary involvement is rare and often mimics tuberculosis or malignancy. We report the case of a 62-year-old woman with diabetes and chronic hookah use presented with persistent fever and cough. Imaging revealed right lower lobe cavitary consolidation with bilateral nodules. Even after extensively investigating, her diagnosis was inconclusive. A detailed dietary history revealed raw milk consumption, while serology confirmed brucellosis. She improved with doxycycline, rifampicin, and streptomycin therapy. This case highlights the diagnostic challenge of pulmonary brucellosis in nonendemic areas and underscores the importance of thorough history and appropriate serological testing.
