Estudio por imagenes en mortinatos: una alternativa a la autopsia

ABSTRACT

Nowadays, imaging techniques are cornerstones for fetal anatomy diagnosis. We present a case of stillborn monocorial twins in which virtual imaging studies are helpful in discarding anatomical defects on the spectrum of oligohydroamnios sequence or Potterïs syndrome. In one of them, inadequate bladder visualization in antenatal ultrasound suggested a renal cause. The other twin was our natural control. CT and MR were performed in both twins at University of Chile Clinical Hospital. Anatomical imaging in different axis, surface 3D and complete skeleton reconstructions were obtained. There are seven clinical syndromes with anatomical defects and congenital renal malformation able to produce oligohydroamnios sequence or Potterïs syndrome described in literature. The images obtained in these cases, allowed us to discard malformations or associated defects related to oligohydroamnios sequence, suggesting a premature ovular disruption. In this study, CT and MR imaging results were more accurate than antenatal ultrasound and similar to fetal autopsy.
