ABSTRACT
There are little available radiological studies concerning bronchogenic carcinoma in the Middle East and very few series have been reported. This urged us to begin a survey for the purpose of studying the disease as it appears on a plain chest film. The project was carried on 116 patients and for a period of nearly two years. The diagnosis was confirmed cytologically, histologically or both on all patients. Pulmonary mass [81%] and atelectasis [29%] were the most common radiographic presentation of bronchogenic carcinoma with higher incidence of both in squamous cell type. It should be emphasized that despite the availability of simple and sophisticated diagnosis methods, the standard chest radiograph remains the simplest and the most helpful and useful diagnosis procedure
