Abstract

<p>We experienced treating a very rare case of extralobar pulmonary sequestration (hereinafter referred to as “this disease”) in a male infant. Preoperatively, he was diagnosed as having extralobar pulmonary sequestration under the diaphragm, and mass removal was performed laparoscopically, but intraoperative findings revealed that the mass was intradiaphragmatic. In this disease, the diagnosis of extralobar pulmonary sequestration is relatively easy if feeding arteries branching from the large circulatory system flowing into the mass can be identified, but its location is not always easy to determine preoperatively. When a mass is located in an unusual place, it is often diagnosed as being close to the diaphragm, such as on or below the diaphragm. Surgical removal is the first choice of treatment owing to the risk of infection and malignancy. Endoscopic surgery is recommended because it is minimally invasive and it has a good field of view. However, the translapse or transthoracic surgical approach may be wrongly selected owing to the difficulty of preoperative location diagnosis. Therefore, in the case of masses close to the diaphragm, it is important to strive for accurate location diagnosis with this disease in mind and to plan surgery with a view to changing the approach during surgery.</p>
