Intraabdominal pulmonary sequestration.

Bronchopulmonary sequestration is an uncommon developmental abnormality that frequently presents as an incidental mass. Differential diagnosis includes malignancy. Reports of extralobar abdominal pulmonary sequestration in adults are sparse. Only 2.5% of all pulmonary sequestrations are detected below the diaphragm. The authors present a case of a 45-year-old woman and a literature review. Computed tomography, magnetic resonance imaging, and operative and pathologic findings are provided. A review of diagnosis and therapy is presented.
