Chronic Headache and Visual Field Loss: Manifestations in a Patient With Chronic Brucellosis Meningitis: Case Report With Brief Literature Review.

Brucellosis is a zoonotic infection caused by Brucella species, often leading to serious complications and presenting diagnostic challenges. A 45-year-old female patient presented with a headache that had persisted for two months and was recently accompanied by visual disturbances. Notably, the patient's headache began 6 weeks postpartum, and she had no prior history of illness, medication use, or headaches. Imaging studies were normal, and cerebrospinal fluid (CSF) analysis revealed meningitis, with a positive Wright test. After excluding other potential causes and considering the patient's consumption of local dairy products, the diagnosis of Brucella meningitis was confirmed. The patient was treated with a standard three-drug regimen for 6 months and was followed throughout the treatment period. Initially, her headache resolved, followed by improvement in visual symptoms. Follow-up serologic tests showed a declining trend in Brucella titers, and perimetry results returned to normal by the fourth month of treatment. This case underscores the importance of including Brucella in the differential diagnosis of patients with chronic meningitis, especially in endemic regions, and highlights the favorable outcomes associated with prompt treatment.
