Infradiaphragmatic pulmonary sequestration combined with cystic adenomatoid malformation: unusual postnatal computed

Abstract:
We present a surgically proven case of infradiaphragmatic pulmonary sequestration combined with cystic adenomatoid malformation. Prenatal magnetic resonance imaging revealed a well-defined hyperintense mass with a hypointense septum in the left infradiaphragmatic region. Postdelivery computed tomography (CT) and 3-month follow-up CT showed replacement of intralesional cystic areas by solid content. Such unusual postnatal CT changes, to our knowledge, have not been previously documented.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
