Multicystic dysplastic kidney and cystic accessory uterine cavity: a new prenatally diagnosed association.

The co-existence of renal and mullerian anomalies is well-recognised. Multicystic dysplastic kidneys (MCDK) are known to be associated with the presence of genital cysts in both males and females, but this is the first report of a prenatally diagnosed MCDK associated with a non-communicating cystic uterine cavity. The management of these abnormalities in childhood is not well-established.
