RETROPERITONEAL PULMONARY SEQUESTRATION - IMAGING FINDINGS, HISTOPATHOLOGIC CORRELATION, AND RELATIONSHIP TO CYSTIC ADENOMATOID MALFORMATION

OBJECTIVE, Retroperitoneal bronchopulmonary sequestrations are rare co ngenital lesions that have been increasingly reported as incidental fi ndings in utero. We present our case material of congenital retroperit oneal sequestration, discuss the reported imaging and histopathologic characteristics of this entity, and provide an approach to subsequent clinical and surgical management. CONCLUSION. Our data suggest that th e imaging findings in retroperitoneal sequestration are characteristic and that faulty mesenchymal induction of pulmonary tissue within the retroperitoneum renders internal development into cystic adenomatoid m alformation the rule rather than the exception. Ln the typical case, s urgical removal is nonemergent.
