Fleischner 2017 guideline for pulmonary nodules
Introduction In the updated Fleischner Society guideline was published. In these cases, follow-up should be considered. Subsequent management based on the most suspicious nodule s. Subsolid nodule SSN A pulmonary nodule with at least partial groundglass appearance Groundglass Opacification with a higher density than the surrounding tissue, not obscuring underlying bronchovascular structures.
No Follow-Up If suspicious, consider follow-up at 2 and 4 years. Subsolid nodules in the adenocarcinomatous spectrum were formerly known as bronchoalveolar carcinoma or BAC.
Perifissural nodules are a separate entity, and likely represent intrapulmonary lymph nodes. For this reason the Fleischner guideline for the management of pulmonary nodules separates high- and low-risk, and does not apply to subjects younger than 35 years, immunocompromised patients or patients with cancer .
Creating an account is free, easy, and takes about 60 seconds. Intra-fissural, perifissural, and subpleural pulmonary nodules. No reliable distinction can be made radiologically, although studies suggest that larger size and a fleischne component are associated with more invasive behaviour. CT in 6 to 12 months, then consider CT in 18 to 24 months.
F,eischner should be obtained on the same transverse, coronal or sagittal reconstructed image, whichever plane reveals the greatest dimensions . CT in 3 to 6 months, then consider CT at 18 to 24 months.
Perifissurally located nodules that do not conform to the morphologic characteristics should be regarded as non-PFN nodules Figure and does require follow-up. Since these risk factors are numerous and flsischner different effects on the malignancy risk, it is proposed to assess final risk categories concerning the probability of malignancy  Table.
Or create a new account it’s free. PFNs can show significant growth rates on serial imaging, sometimes comparable to malignant nodules. Please fill out required fields. If unchanged, consider CT at 2 and 4 years. In the updated Fleischner Society guideline was published. CT in 3 to 6 months, then consider CT in 18 to 24 months.

Heber MacMahon’s publications, visit PubMed. From the Fleischner Society The currently available guidelines recommend that when small nodules have a perifissural or other juxtapleural location and a morphology consistent with an intrapulmonary lymph node, follow-up CT is not recommended, even if the average dimension exceeds 6 mm. If suspicious morphology or upper lobe location, consider month follow-up.
Lung Cancer Risk Factors: Because of the slower growth rate, the total follow-up period for persistent subsolid nodules has been increased to 5 years. To differentiate between transient or persistent subsolid nodules fleischnfr follow-up CT should be obtained.
CT in 6 to 12 months to confirm persitance, then CT every 2 years until 5 years. Subsolid nodules Most subsolid nodules are transient and the result gudelines infection or hemorrhage. Incidental pulmonary nodules on imaging can be challenging to evaluate.
Diameter of lung nodule is the average of the short and long axes, rounded to the whole millimeter.
CT in 3 flelschner 6 months, then obtain CT in 18 to 24 months. The latter differentiates between a typical and atypical PFN see Figure.
