We here report a case of prenatally diagnosed enterolithiasis at 18weeks of gestation, showing multiple hyperechogenic foci rolling within the bowel fluid after peristalsis. The size of the dilated bowel gradually increased during pregnancy. Magnetic resonance image demonstrated the dilated lower bowel with blind-ending rectum. A postnatal contrast medium study with retrograde urethrography revealed a middle imperforate anus and a rectourethral fistula. A careful examination, even before 20weeks of gestation, is extremely useful in demonstrating intraluminal coarse calcifications within an echogenic bowel.
