Objective:

To report a rare case of brucellosis presenting with acute kidney injury and haemophagocytic syndrome, a condition characterized by excessive activation of the immune system.

Key Findings:

• The patient presented with unexplained fever, progressive pancytopenia, and elevated serum creatinine.
• Blood culture confirmed the presence of Brucella.
• Imaging showed increased renal cortical echogenicity, indicating renal involvement.

Interpretation:

The case emphasizes the importance of considering rare pathogens like Brucella in patients with unexplained fever and clinical features that deviate from typical presentations.

Limitations:

• The case is based on a single patient, limiting generalizability to broader populations.
• Diagnostic challenges may lead to underreporting of brucellosis cases, affecting the understanding of its prevalence.

Conclusion:

The patient showed significant improvement following appropriate treatment, highlighting the need for awareness of rare complications associated with brucellosis to enhance early diagnosis and management.
