Solitary pulmonary nodules are usually identified on routine chest radiographs in asymptomatic patients. Most nodules have a begin cause but broncogenic carcinoma, metastases and other malignant process are important causes as well and must be excluded in differential diagnosis. The present study includes 51 patients having solitary pulmonary lesion in x-ray chest. Of the 51 patients, malignancy was confirmed in 52.94%. Pneumonia in 21.56%, tuberculosis in 15.68%, Hydatid cyst in 7.84% and A.V. malformation in 1.96%.
