RESUMO
A pulmonary sequestration is a mass of nonfunctioning, embryonic lung tissue that has no communication with the normal bronchial system and is usually supplied by an aberrant systemic artery. Bilateral intrapulmonary sequestration is very rare. This case was a 16 months old boy who showed persistent right lower lobe infiltration on chest X-ray. We found the consolidation lesions on left lower lobe and right lower basal segment which had the multiple cyst like lesions on the chest computed tomography. We confirmed the bilateral intrapulmonary sequestration by angiography which showed each sequestrated tissue being supplied by 2 aberrant arteries. The lobectomy of left lower lobe and the ligation of right aberrant artery were performed. Four months later, residual right lower lobe sequestrated tissue regressed markedly on the following chest computed tomography. Herein, we report a case of bilateral intrapulmonary sequestration which was successfully treated by the ligation of aberrant artery without subsequent complications.
