When reviewing a case of miliary nodules the important issues are:

• clinical presentation and detailed relevant medical history, e.g., history of silicosis, drug and substance abuse usage, ethnicity and immune status, previous history of malignancy.
• location of nodules, i.e. centrilobular, perilymphatic or random in location
• zonal distribution of the nodules, areas of relative sparing.
• associated findings, i.e.  pulmonary fibrosis,  ground glass opacification, mediastinal nodes, if present are the nodes calcified, pleural effusion
• previous imaging if available can be most helpful, the answer may lie within the patient's imaging folder
