Kidney dysplasia 

Fabrice Cuillier, MD.

Case report

A 40-year-old woman G3 P2, with an unremarkable personal or familiar history presented to our department at 18th week of pregnancy. Her ultrasound scan at 13th week was normal, but she refused biochemical triple test and amniocentesis. We discovered severe oligohydramnios with abnormal structure of the fetal kidneys. The fetal growth was consistent with the gestational weeks. The findings were the same at 19th and 20th week and the kidney seemed more echogenic with unrecognizible corticomedullary differentiation.

The patient had spontaneous miscarriage at 21st week, but refused anatomopathological study of the baby. We assume the fetal kidney dysplasia to be the etiological factor responsible for the ultrasound findings.
