Calcified meconium balls in a newborn: an unusual case with imperforate anus, rectourinary fistula, colpocephaly, and agenesis of corpus callosum

Abstract

Calcified intraluminal meconium is a rare finding in newborn infants. It is often associated with communication between the urinary and gastrointestinal tracts. Intra-abdominal calcifications are unusual radiographic findings in the newborn and can easily be misinterpreted as meconium peritonitis. We report on a newborn infant with anorectal malformation, meconium balls, intraluminal calcifications, colpocephaly, and agenesis of the corpus callosum, a rare association.

Enterolithiasis in a Newborn with Anorectal Malformation

“…Meconium peritonitis causes diffuse, linear, plaque-like areas of calcification throughout the abdomen; in male neonates, calcification in scrotum is an important sign of meconium peritonitis. [1,2] Enterolithiasis are intraluminal and usually displace with peristalsis and ultimately evacuated if distal obstruction is not present. Plain radiography, ultrasonography, and MCUG (in case of recto-urinary fistula) demonstrate intracolonic location of the calcifications.…”

[1,2] There are two types of enterolithiasis: string of pearls calcification (associated with hereditary multiple gastrointestinal atresias); and punctuate or rounded calcifications (associated with anorectal malformation, single intestinal atresias, colonic aganglionosis etc.).
