title: Intra-abdominal pulmonary sequestration: a case report and literature review.
abstract: Pulmonary sequestration is a rare congenital malformation mostly located in the thorax, while intra-abdominal pulmonary sequestration is an extremely rare type of pulmonary sequestration usually diagnosed during the first 6 months of life. Only 1 case of intra-abdominal pulmonary sequestration in a patient older than 60 years has been reported in the current literature. It is difficult to differentiate an intra-abdominal pulmonary sequestration from other retroperitoneal tumors. A definitive diagnosis is always made by histological examination. Intra-abdominal pulmonary sequestration commonly responds well to surgical resection and is associated with excellent results and prognosis. The authors present the case of a 74-year-old asymptomatic man with a retroperitoneal mass which was completely excised and revealed by histopathological study to be an intra-abdominal pulmonary sequestration.
