AbstractBackground: Tuberculosis is one of the world’s potentially life-threatening communicable diseases. The disease burden is more in developing countries. Pulmonary tuberculosis can lead to several serious complications. Unilateral lung destruction and complete destruction of a major part of lung or entire lung is common, and it results from parenchymal and airway involvement. Chest radiographs & computed tomography of chest is the mainstay in the detection of the destroyed lung.
Objective: To describe the radiographic and computed tomographic findings in patients with tuberculous unilateral lung destruction.
Martial and Methods: In this report, we present a review of 50 patients withUTLD secondary to TB. Case records of the patients were retrospectively evaluated for clinical data and treatment history.Retrospective review of the images was performed by two radiologists and relevant findings were studied. Important findings were noted.
Results: A total of 50 patients with unilateral complete lung destruction were evaluated. Age ranged from 25 to 68 years. Chest radiograph showed a small opacified hemithorax with mediastinal shift, crowding of ribs. Computed tomography showed loss of lung volume with fibrosis, bronchiectasis, and cavities. Left lung destruction was predominant (41/50, 82%). 22(44%) patients had fibrosis or cavities in contralateral lung. 16 (32%) patients had features of active disease in contralateral lung. 3(6%) patients had aspergilloma in the affected lung.
Conclusion: Males are more commonly affected. Left lung is more commonly involved compared to the right. Characteristic radiological findings are unilateral volume loss, reduced size of the ipsilateral pulmonary artery and pulmonary veins and hyperinflation and herniation of contralateral lung.
