Neonatal cholelithiasis, an unusual association with twin anemia and polycythemia sequence: A case report

Gallstones are rarely seen in preterm neonates with most cases reported in term singletons without any identifiable risk factors. Although most cases are self-resolving, neonatal gallstones can be associated with significant complications. We report a case of 34-week gestation monochorionic diamniotic twins with twin anemia-polycythemia sequence (TAPS) where the recipient twin presented with gallstones on the first day of life. To the best of our knowledge, this is the first case of gallstones in preterm twins following TAPS.
