To evaluate the diagnostic utility of sonar guided biopsy techniques in diagnosing tuberculous pleural effusions.
Conducted transthoracic ultrasound on 50 patients with suspected tuberculous pleural effusion.
Patients underwent either Abrams needle biopsies or True-Cut needle biopsies.
Evaluated the presence of pleural tissue and diagnostic sensitivity of both biopsy methods.
Pleural tuberculosis was diagnosed in 31 out of 50 patients.
Abrams needle biopsy had a sensitivity of 83.8%, diagnosing tuberculosis in 26 patients.
True-Cut needle biopsy had a sensitivity of 54.8%, diagnosing tuberculosis in 17 patients.
