A case of atypical multicystic dysplastic kidney in the fetus

This article describes a case of the dynamic ultrasound examination of multicystic dysplasia of the fetal left kidney from 20 weeks of gestation until the birth. The huge enlargement of one of the cysts with an abdominal compression was revealed at 24–25 weeks of gestation. The aspiration of the contents of the cyst was performed triples. The cyst regression was marked at 36–37 weeks of gestation. The postnatal ultrasound examination confirmed the multicystic dysplasia of the left kidney.

Congenital Cytomegalovirus Infection: A Cause of Renal Dysplasia?

Cytomegalovirus (CMV) infection is one of the most frequently encountered viral infections of the fetus and induces a wide range of histologic and clinical manifestations. Congenital abnormalities are typically restricted to the central nervous system despite evidence of CMV inclusions occurring in most epithelial cells. Although tissue injury and even glomerulonephritis have been observed in congenital CMV infections, renal multicystic dysplasia has not been reported. Herein, we describe a case of unilateral renal dysplasia in a 19-week fetus with concurrent CMV infection. We believe the present case to be the first description of a virus apparently inducing renal multicystic dysplasia.
