title: Retroperitoneal pulmonary sequestration: imaging findings, histopathologic correlation, and relationship to cystic adenomatoid malformation.
abstract: OBJECTIVE
  Retroperitoneal bronchopulmonary sequestrations are rare congenital lesions that have been increasingly reported as incidental findings in utero. We present our case material of congenital retroperitoneal sequestration, discuss the reported imaging and histopathologic characteristics of this entity, and provide an approach to subsequent clinical and surgical management.
  
  
  CONCLUSIONS
  Our data suggest that the imaging findings in retroperitoneal sequestration are characteristic and that faulty mesenchymal induction of pulmonary tissue within the retroperitoneum renders internal development into cystic adenomatoid malformation the rule rather than the exception. In the typical case, surgical removal is nonemergent.
