Nodules by definition are lung opacities less than 3 cm in size . Subcentimeter pulmonary nodules always pose a dilemma to reporting radiologist. Radiologist’s role doesn’t get over by just describing the number and size of the nodules. It is important to guide the referring physician and patient about the next course of action that may range from follow-up CT to percutaneous CT-guided intervention. In certain cases, CT can provide additional clues for the underlying diseases accounting for pulmonary nodules.
