Both patchy and nodular shadows are needed in conjunction with the clinical history to determine the severity of the lesion. If the nodule in the lung is an isolated nodule, and the nodule is not well formed, with lobulation, burr, bronchial truncation, and adjacent pleural pulling depression, this nodule may be considered to have a high likelihood of being a malignant tumor. This nodule would be more serious than a patchy shadow. Patchy images are usually more likely to be inflammatory. If there are multiple nodules together with a patchy blurred image, it is possible that both are referring to inflammation. There is also another scenario where if a patient with a history of neoplasia has nodules, and the nodule pattern is also more glossy and diffuse in both lungs, then these nodules need to be considered if they are multiple metastases to both lungs from metastatic tumors.
