Calcified intraluminal meconium in newborn males with imperforate anus. Enterolithiasis in the newborn.Am J Roentgenol Radium Ther Nucl Med. 1975 Oct; 125(2):449-55.AJ
Five cases are reported and reference is made to 3 previous similar cases of calcified intraluminal meconium in newborn males with "imperforate anus." A rectourinary fistula was found in most of the patients; none of the cases had meconium peritonitis. The calcifications may develop in areas of prolonged stasis; the possible added role of the mixture of urine and meconium in utero is raised.
