This short communication is the result of our intention to popularize a quick overview on the pulmonary sequestration and the relative radiological evaluation, through the standard chest radiography and the most modern computed tomography. Pulmonary sequestration represents from 0.1% to 6% of all structural lung diseases and developmental malformations: it has been known since 1861 and it has been divided into intra and extralobar types since 1946. When symptomatic it manifests with recurrent and often non-specific respiratory symptoms: this fact is the main reason why there is a still high rate of incorrect or late diagnoses. We would like to focus the reader’s attention on the radiological features of patients affected with pulmonary sequestration, referring to some significant and original cases and to the evidence in Literature: as primum movens the chest radiography, often confusing and inconclusive, up to the computed tomography which represents the diagnostic gold standard. The differences between intra and extra lobar forms of pulmonary sequestration are emphasized, and some suggestions are given regarding the CT acquisition technique. Finally, mention is made of the role of Interventional Radiology in the treatment planning. The wish of our work is to communicate the important role of medical and interventional radiology in pulmonary sequestration disease, that is clear both in the diagnostic and treatment phases. Indeed, an accurate imaging study is a guide to surgery and prevents intra-operative mortality and morbidity.
