title: [A baby with an abdomen full of balls].
abstract: A 2-day-old girl with an urethrorectal fistula as part of an anorectal septum malformation showed intra-abdominal densities in the colon on radiologic examination, due to calcified meconium balls. This calcification is caused by the presence of urine in the intestinal tract and therefore confirms the presence of an urethrorectal fistula.
