Neonatal abdominal calcification: is it always meconium peritonitis?
Intraluminal meconium calcifications are a rare cause of neonatal abdominal calcifications and can easily be misinterpreted as meconium peritonitis. We report three patients with anorectal anomalies, rectourethral fistula, and intraluminal calcified meconium. Intestinal stasis and mixing of urine and meconium may be predisposing factors for the calcification of meconium. Intraluminal calcifications appear as discrete punctate flecks within the distribution of the bowel, in contrast to meconium peritonitis, where the calcifications are linear and plaque-like, occurring anywhere in the abdominal cavity and scrotum. Careful differentiation of abdominal calcifications will allow more appropriate planning of the need and timing of surgery and can suggest the possibility of other anomalies that may not be suspected initially.
