Extraluminal calcified meconium is found frequently by prenatal ultrasound in cases with bowel perforation and meconium peritonitis. Intraluminal intestinal meconium calcifications are rarely seen in prenatal sonography. Meconium calcifications result from a mixture of meconium and urine that indicates a connection between intestinal and urinary tract. We report a case of a male newborn prenatally diagnosed with intraluminal echogenic calcifications at 23 weeks of gestation, suggesting an anorectal malformation (ARM) with rectourinary fistula.
