Intralobar pulmonary sequestration: diagnostic expertise

Abstract

An obese 22-year-old man with a history of recurrent respiratory infections presented to the emergency room with left pleuritic chest pain, productive cough with mucupurulent sputum and an axillary temperature of 37.7°C. Blood work showed elevated inflammatory parameters and chest X-ray was relevant for heterogeneous infiltration in the left base and opacity of the left costophrenic angle. An angio-CT scan revealed areas of bilateral consolidation with presence of an arterial branch originating from the aorta to the collected area of the left lower lobe, consistent with a respiratory infection grafted on a intralobar pulmonary sequestration of the left lung base. The infectious process was treated and the patient was planned for a lower left lobectomy.

Computed Tomography findings of atypical intralobar pulmonary sequestration: Research Article

“…4 Extralobar pulmonary sequestration (10%-25%) completely separates from normal lung tissue and has its own pleura. 4,5 The typical features of intralobar pulmonary sequestration include arterial supply from the thoracic aorta by solitary branch, venous drainage via pulmonary veins, left lower lobe involvement, and heterogenous solid mass appearance. The lesion may be seen as a cystic mass including air when it is infected.…”
