title: Predilection of zonal involvement and pattern of opacities in chest x-ray in post primary pulmonary tuberculosis.
abstract: A cross sectional analysis of chest radiograph was performed in 100 patients with tuberculosis to observe the recent trends of radiographic presentation. The study was done from April to December, 2009, in Sir Salimullah Medical College and Mitford Hospital, Dhaka, Bangladesh. The chest x-ray findings were analyzed and zonal involvement and pattern of opacities were categorized and compared. Majority of patients (45%) showed involvement of the upper zone. Dominating lesion was consolidation (25%). Most of the patients were between 15-40 years. Forty-four percent patients were sputum positive for Acid Fast Bacilli and cavitation was the dominant lesion among them. Chest x-ray of patients with post primary tuberculosis shows involvement predominantly in the upper zone of lung. The most common opacity was consolidation. This correlates with different studies done over different population.
