The purpose of our educational exhibit is to: 1/ Describe different types of pulmonary nodule. 2/ Describe the conduct to adopt in the current practice.
The detection of an incidental pulmonary nodule on chest CT is not an exceptional situation in the routine practice.
The etiologies are varied,
including mainly tumors,
infections and inflammatory diseases.
The most frequent malignant lesions are pulmonary metastases and primary bronchopulmonary cancers.
Findings and procedure details
There are three types of pulmonary nodules: solid,
subsolid and groundglas.
Depending on the type,
multiplicity and the risk factors of the patient,
the management decision differs referring to the Fleischner Guidelines Fig.
1. The sign of the corona radiata or spiculated margins is very evocative of malignancy Fig.
2. It is important to detect an obstruction of lung vessels and bronchi,
which is highly suggestive of malignancy; however some rare tumors,
The discovery of a pulmonary nodule is a frequent situation.
By studying several aspects and referring to the Fleischner Guidelines we could optimize the management of pulmonary nodules.
