Potter sequence complicated by congenital cystic lesion of the bladder.

We report a case complicated by oligohydramnios, pulmonary hypoplasia, bilateral renal dysplasia, and cystic lesion of the bladder. He was clinically compatible with Potter sequence. Congenital cystic bladder is the rarest form of the bladder. We can find no report of Potter sequence complicated by cystic lesion of the bladder. This lesion was similar to multilocular bladder. The diagnosis was confirmed it by autopsy, magnetic resonance imaging, and urography after his death.
