The Fleischner Society Guidelines for management of solid nodules were published in , and separate guidelines for subsolid nodules were issued in The Fleischner Society has once again updated guidelines addressing incidentally discovered pulmonary nodules. Key differences from Diagnostic criteria for idiopathic pulmonary fibrosis: a Fleischner Society White Guidelines for Management of Incidental Pulmonary Nodules Detected on CT.

These new guidelines should reduce the number of unnecessary follow-up examinations and provide clear management decisions. They are discussed in the last chapter. Subcategory of ‘Diagnosis’ designed to be very sensitive Rule Out.

CT at months to confirm persistence. Subsequent management based on the most suspicious nodule s.

If grows or increasingly solid, consider resection. Log In Create Account. No Follow-Up If suspicious, consider follow-up at 2 and 4 years.

Lung Cancer Risk Factors: The images show a 7 mm pure groundglass subsolid nodule in the right upper lobe. Creating an account is free, easy, and takes about 60 seconds.

About the Creator Dr.

From the Fleischner Society CT in 3 to 6 months, then obtain CT at 18 to 24 months. Don’t let this happen to Your Patient:. The principal investigators of the study request that you use the official version of the modified score here. This terminology should no longer be used.


If unchanged, consider CT at 2 and 4 years. Patients who have a known cancer. Or create a new account it’s free. Upper pulmonary lobe location of nodule.

Fleischner 2017 guideline for pulmonary nodules

Choose the appropriate features. Defining high- or low-risk is currently more difficult than it was in the old guideline. This confirmed prior results of Ahn et al.

If unchanged and solid component below 6mm, CT annualy for 5 years. Because of the slower growth rate, the total follow-up period for persistent subsolid nodules has been increased to 5 years. CT in 6 to 12 months, then obtain CT in 18 to 24 months. CT at months. Aortic Diameter – Adult. This is new compared to the prior guideline, in which dimensions were averaged diameters in the axial plane only [2].

Previously a high-risk subject was identified based on a history of heavy smoking, history of lung cancer in a first-degree relative or exposure to asbestos, radon or uranium. CT in 6 to 12 months, then consider CT in 18 to 24 months. A new pathology-based classification for adenocarcinoma was introduced in and this current classification guideline distinction guidelinez Heber MacMahon’s publications, visit PubMed.

Formula Choose the appropriate features. Do not use for lung cancer screening or in patients with known primary cancer or immunosuppression. Follow-up is therefore a commonly used strategy.


Perifissurally located nodules that do not conform to the morphologic characteristics should be regarded as non-PFN nodules Figure and does require follow-up. From the Fleischner Society The likelihood of malignancy is different for an incidentally found pulmonary nodule in the lower lobe of a relatively young patient compared to a nodule in the upper lobe of a high-risk heavy smoker, or in a patient with a known or suspected malignancy.

These guidelines provide an accepted framework for management. Their location is within 15 mm of the fissure or the pleura. If unchanged, consider CT in guideoines and 4 years.

No reliable distinction can be made radiologically, although studies suggest that larger size and a solid component are associated with more invasive behaviour. CT in 6 to 12 months to confirm persitance, then CT every 2 years until 5 years. On follow-up CT this proved to be a transient subsolid nodule.

These images show fleischer pure groundglass subsolid nodule in the right lower lobe. Perifissural nodules are a separate entity, and likely represent intrapulmonary lymph nodes. CT fleichner 3 to 6 months. Transient subsolid nodules usually represent infection or alveolar hemorrhage.
