Solid pulmonary nodules can represent various etiologies: - benign granulomas - focal scar - intrapulmonary lymph nodes - primary malignancies - metastatic disease. Perifissural nodules are a separate entity, since they usually represent intrapulmonary lymph nodes, which are benign and need no follow up. They are discussed in the last chapter. In another article we presented some features that can help to differentiate between benign and malignant lesions (click here) Unfortunately, there is considerable overlap and often no definitive answer can be given based on imaging morphology. Follow-up is therefore a commonly used strategy. #Diagnosis #Radiology #Pulmonary #Fleischner #Guideline #Solid #Nodule #PulmonaryNodule #Followup #RadiologyAssistant
