Tuberculosis and Malignancy Coexistence with Cavitary Lesion in the Lung Radiologically

Abstract

When a cavity of characterized radiolucent zone is observed in lung graphy, the fist thing that comes to mind aretuberculosis, bronchial cancer, bacterial infections (as nocardia) or rarely wegener granulomatosis. Clinical suspicionor abnormal radiography require further examination in the name of lung cancer. Computerized tomography (CT) isthe basic screening method. While position emission tomography (PET) is rather used for staging, magnetic resonance(MR) is used for problem solving. Adenocarcinoma forms 30% of all lung cancers. İt is the most common type of canceramong women and non-smoker patients. Cavitation is rare in lung adenocarcinomas (2%). If there is cavitation, it is usually in the form of a single cavity. The most common cavitation in lung cancers is in epidermoid carcinoma (82%). In thelight of these information, we would like to present 35-year-old male patient whose chest radiography is compatiblewith cavity and has ARB (+) but diagnosed with adenocarcinoma.
