Intralobar sequestration accounts for 75% of pulmonary sequestrations. It is characterized by the presence of nonfunctional parenchymal lung tissue, receiving systemic arterial blood supply. We conducted a retrospective medical records review of all patients evaluated and treated in our pulmonary department of military hospital of Tunisia with diagnosis of PS from January 2007 through December 2015. Among them, we report 5 cases of intralobar pulmonary sequestrations operated. There are three women and two men; the mean age is 27.6 years. The sequestration was intralobar in all cases. Clinical presentations were chest pain and productive cough in three cases. Chest X-ray showed left basal opacity in three cases, bilateral basal reticulonodular opacities in one case and round hydric opacity in the right lower lobe in one other case. Computed tomography was performed and revealed an aberrant systemic artery born from the lateral side of aorta supplying a left lower lobe sequestration in four cases and a right lower lobe mass in only one case. The confirmation was operative in all cases and histologic only in three cases. All patients were treated by lobectomy. Only one case presented with a pulmonary sequestration combined with tuberculosis and he was treated firstly by antituberculous chemotherapy. The results were excellent with a favorable clinical course and the mortality was nil.
