Abstract

Background: Tuberculosis (TB) remains a significant global health challenge, with a notable fraction of cases occurring outside the lungs (extrapulmonary tuberculosis, EPTB). The diagnosis of EPTB can be complex, particularly when chest radiographs appear normal. Methods: This cross-sectional study included 200 patients diagnosed with EPTB, who exhibited normal chest radiograph findings. We aimed to identify characteristics associated with sputum culture positivity among these patients. Results: Key findings highlight that certain demographic and clinical features were significantly associated with sputum culture positivity in EPTB patients with normal chest radiographs. These characteristics include age, gender, and specific symptoms, among others. Conclusion: Understanding the predictors of sputum culture positivity in EPTB patients can aid in early diagnosis and targeted treatment strategies, ultimately improving patient outcomes.
