Miliary Metastases on Chest X-ray A Radiologic Guide to Diagnosis and Management Figure. Chest radiograph demonstrating miliary nodules: innumerable small, uniform, well-circumscribed opacities diffusely distributed throughout both lungs, indicative of hematogenous metastatic spread. Introduction Miliary metastases are a striking radiographic pattern characterized by the hematogenous spread of cancer to the lungs, resulting in innumerable micronodular opacities on chest imaging. This pattern is reminiscent of millet seeds, giving rise to the term “miliary.” Recognizing this pattern is crucial for early oncologic intervention, especially in cases where the primary tumor is occult. In this article, based on a radiology case from SVUH Radiology , we delve deep into the clinical and imaging characteristics of miliary metastases, supported by expert-level insights. Discussion Cause & Etiology Miliary metastases occur when malignant cells enter the bloodstr...
