Revising the classification of lung sequestrations

Leonor Alamo, Sarah Saltiel, Estelle TenischUniversity Hospital of Lausanne (CHUV) and University of Lausanne (UNIL). Switzerland Clinical ImagingClin Imaging 2021; 77: 92-97DOI: 10.1016/j.clinimag.2021.02.024 AbstractPurposes: The classification of lung sequestrations distinguishes between extralobar and intralobar types, according to their venous drainage – systemic vs pulmonary – and the presence or absence of independent pleura. However, imaging, surgical and/or
