Miliary Pattern

Miliary Pattern - Its name comes from a distinctive pattern seen on a chest radiograph of many tiny spots distributed throughout the lung fields with the appearance similar to millet seeds—thus the. Thus, this pattern is representative of a lymphohematogenous dissemination of disease process. A heterogeneous group of conditions comprising more than 80 entities may display miliary pattern. Web the differential diagnosis of miliary pattern on chest radiography includes miliary tuberculosis (tb), histoplasmosis, sarcoidosis, pneumoconiosis, bronchoalveolar carcinoma, pulmonary siderosis, and hematogenous metastases from primary cancers of thyroid, kidney, trophoblast, and some of the sarcomas. Web miliary tb is a potentially fatal, disseminated form of the disease arising from hematogenous tubercle bacilli spread throughout the lungs and other organs. Web the miliary pattern is thought to occur when organisms that have gained access to the blood stream become lodged in the capillary beds and proliferate locally. Web miliary tb can arise as a result of progressive primary infection or via reactivation of a latent focus with subsequent spread via the bloodstream. Web the main entities that manifest as miliary nodules are tuberculosis, fungal infections, and metastatic disease. The clinical manifestations, diagnosis, treatment, and prevention of miliary tb will be reviewed here. Web miliary nodules are generated when the celluar defense mechanism to an infectious agent is either ineffective or there is an underlying infiltrative process which tends to spread through lung interstitium.

Web miliary tb can arise as a result of progressive primary infection or via reactivation of a latent focus with subsequent spread via the bloodstream. Web miliary pattern is an uncommon presentation in lung malignancies and should be considered especially in young females. Web the differential diagnosis of miliary pattern on chest radiography includes miliary tuberculosis (tb), histoplasmosis, sarcoidosis, pneumoconiosis, bronchoalveolar carcinoma, pulmonary siderosis, and hematogenous metastases from primary cancers of thyroid, kidney, trophoblast, and some of the sarcomas.

Web The Main Entities That Manifest As Miliary Nodules Are Tuberculosis, Fungal Infections, And Metastatic Disease.

A heterogeneous group of conditions comprising more than 80 entities may display miliary pattern. It is useful to divide these patients into those who are febrile and those who are not. The clinical data and other associated imaging findings play an essential role in the differential diagnosis of miliary micronodules. Web miliary pattern consists with the presence of multiple small (usually 1 to 3 mm in diameter) nodules in the lung with sharp margins.
