Recurrent Pneumonia as a Manifestation of Pulmonary Sequestration. Case Report

Abstract

Pulmonary sequestration is a congenital respiratory disease that involves the pulmonary parenchymaand its vasculature. It can be divided into intralobar or extralobar depending on its relationshipwith normal visceral pleura. The extralobar subtype is usually diagnosed prenatally or in the firstmonths of life, while the intralobar occurs in young adults. It represents approximately 0.15-6.4%of all congenital lung malformations and does not show differences with respect to sex with a 1:1ratio. We present the case of an average adult male patient with recurrent pneumonia in whommultiples imaging studies are performed, with tomographic findings compatible with intralobarpulmonary sequestration in the left posterior basal segment, with the aim of performing a literaturereview to raise a discussion on the importance of the proper and early diagnosis of this pathology.It is necessary to have a high clinical suspicion -it is a disease of variable presentation-, to requestthe most appropriate imaging study, since the images are those that give the definitive diagnosisof pulmonary sequestration. In some cases, management can be performed in a minimally invasivemanner by interventional radiology, as in this case.
