Miliary pattern consists with the presence of multiple small (usually 1 to 3 mm in diameter) nodules in the lung with sharp margins.Aims:A heterogeneous group of conditions comprising more than 80 entities may display miliary pattern. We expose the most common entities. The radiologic features that help in the differential diagnosis are discussed.Methods:We report the cases of 20 patients (12 women and 8 men) with military lung disease. They were aged between 14 and 76 years. All of them were explored by a chest radiography and a high-resolution computed tomography.Results:According to the distribution of the nodules in relation to the secondary lobule, high-resolution computed tomography findings divide miliary patterns into 3 groups: centrilobular, perilymphatic, and random presentation. The entities found with this pattern are miliary tuberculosis (12 cases),sarcoidosis (2 cases), adenocarcinoma (3 cases), metastases (1 case), and silicosis (2 cases).ConclusionHigh-resolution computed tomography can help to narrow the differential diagnosis of miliary lung diseases. In selected cases the distribution of the nodules, associated radiologic findings and clinical features point to a definite etiologic diagnosis. ER -
