Intralobar pulmonary sequestration is characterized by the presence of nonfunctional lung parenchyma receiving blood supply from a systemic artery and lacking normal communication with tracheobronchial tree.[1] Commonly sequestration is supplied by artery from descending thoracic aorta and abdominal aorta. Here, we report a case of intralobar pulmonary sequestration having arterial supply from the right renal artery.

A 30-year-old female presented with repeated episodes of right-sided chest pain, intermittent fever, and cough since 10 years. X-ray chest showed a relatively well-defined radiopacity in the right lower lung zone with a rounded border superiorly and obscured the right hemidiaphragm inferiorly. Contrast enhanced CT of the chest demonstrated a multiseptated cystic segment of the lung in the right lower lobe, some of the locules showing air-fluid levels [Figure 1]. An aberrant artery was seen arising from the proximal right renal artery 4-mm distal to its origin and coursing upward to the right thorax to supply this abnormal segment of the lung [Figure 2]. The venous drainage of the segment was through the inferior right pulmonary vein.
Figure 1: Axial contrast-enhanced computed tomography mediastinal (a) and lung (b) window shows multicystic sequestrated segment of the lung in the right lower lobe with few internal air-fluid levels. A small segment of the aberrant feeding artery (arrow in a) is also seen

Pulmonary sequestration comprises dysplastic lung tissue separated from the tracheobronchial tree and receiving its blood supply from a systemic artery rather than a pulmonary arterial branch.[1] Recurrent pneumonia and hemoptysis are the most common presentation. Pulmonary sequestration is divided into intralobar and extralobar types. Intralobar sequestration is surrounded by the normal lung tissue without separate pleura whereas extralobar type has its own pleura. Intralobar pulmonary sequestration is the more common type, presents in older children and adolescents. Usually, intralobar pulmonary sequestration has a single feeding artery; however, multiple systemic arterial supply can be seen. Arterial supply of pulmonary sequestration commonly originates from thoracic aorta followed by abdominal aorta and less commonly from intercostal artery, phrenic artery, subclavian artery, pulmonary artery, left gastric artery, coronary artery, and celiac trunk.[2] Arterial supply from renal artery is very rare, only few cases have been reported.[3] CT angiography is the noninvasive diagnostic modality of choice as it can show the abnormal lung parenchyma as well as one or more abnormal arterial supply to the sequestration. Surgical removal of the sequestrated segment is the treatment of choice as the sequestrated lung remains to be a source of infection. It is important to identify the arterial supply and venous drainage preoperatively to prevent the injury of unidentified vessels leading to massive intraoperative hemorrhage. Preoperative embolization of the anomalous vessels may be helpful in reducing intraoperative blood loss.[4]
