A rare case of necrotizing pneumonia due to brucellosis with blood and urine culture positivity.

Brucellosis is a zoonotic infectious disease widely seen worldwide, especially in developing countries and endemic regions where livestock farming is common. Brucella primarily affects the reticuloendothelial system and joints but can also localize in the central nervous, cardiovascular, and genitourinary systems. Pulmonary and urinary involvements are very rarely reported in the literature. This article presents a 24-year-old male patient who was admitted with syncope. Initially admitted with a preliminary diagnosis of Crimean-Congo hemorrhagic fever, the first thoracic computed tomography findings of the patient were considered alveolar hemorrhage. However, due to the growth of Brucella spp. in blood and urine cultures, the patient was diagnosed with necrotizing pneumonia due to brucellosis.
