Abstract              Background: Lung cancer has for many years been a disease with poor prognosis. Lung cancer may be detected in a variety of different ways. Sometimes, there may not be any signs or symptoms of the disease, but it may be discovered during other medical procedures. Accurately determining the diagnosis and stage of lung cancer is important to enable patients to be offered the best possible treatment. Aim and objective: To study the radiological manifestations in patients of lung cancer. Material and methods: A cross-sectional study carried out on 58 primary lung cancer patients in a tertiary level hospital and teaching center. chest x-ray USG done on all patients. Ultra sonography of Chest was done to see for fluid/mass/plural nodules. USG guidance was used for pleural tapping and biopsies in case of minimal or loculated effusions and for FNAC of pulmonary masses. Results and discussion: Incidence of lung carcinoma was found to be most common in the 6th decade. Male incidence was more than female 2.86:1. Conclusion: Right lung (62.06%) was more often affected than the left (37.93%) with the preponderance of upper lobes. Radiologically centrally situated lesions were mostly of squamous cell carcinoma (57.14%) followed by small cell carcinoma (28.57%).53.44% patients were showing mass lesion on X-ray chest; and 27(46.55%) presented with pleural effusion on USG.
