Learning objectives Pulmonary nodules are a common finding in imaging, but their interpretation is crucial for effective patient management. This article aims to perceive the new definition of pulmonary nodules and micronodules based on the new Glossary of Terms for thoracic imaging of the Fleischner Society.It will precise how to characterize a pulmonary nodule, focusing on key diagnostic features and help you determine malignant features. By aligning with the latest terminology, this resource ensures more precise and efficient evaluation of pulmonary nodules.
Read more Background Fleischner Society have compiled a new glossory of Terms for Thoracic Imaging published in 2024. New terms and concepts have emerged including new definition of pulmonary nodules, which seeks to clarify and refine the evaluation of these common findings in medical imaging.It aims to establish a standardization of terminology and, thereby, to facilitate communications between radiologists and other clinicians.
Read more Findings and procedure details A nodule is currently defined as a circumscribed opacity less than or equalto 30 mm in average diameter and larger than 6 mm.A rounded lesion less than 6 mm in diameter should be called micronodule.The latest Fleischner Glossary of Terms seeks to standardize the description and reporting of nodules:- Shape and Margins: Nodules can be described as round (Fig1), ovoid, or polygonal in shape, with margins that may be well-defined (fig1) or ill-defined. Irregular borders can be lobulated or spiculated...
Read more Conclusion The new glossory of terms of Fleischner Society provides new definition ofpulmonary nodule. It precises how to caracterise and report nodules intendingto standardize description and thereby to facilitate communication betweenexperts.Radiologists should acknowledge and refer to this consensus proposal.The treatment of an individual with a pulmonary nodule should be guided by the probability that the nodule is malignant and based on Fleischner Society recommendations of 2017.
