The authors present an anterior rectal cyst in a 14-month-old girl. This ra
re variant of rectal duplications presented with . recurrent urinary infect
ions. The diagnosis was challenging in view of the multiple differential di
agnoses to be considered. Magnetic resonance imaging appeared to be the mos
t accurate preoperative investigation. The cyst was removed uneventfully by
partial excision and mucosal ablation. An awareness of this variant can le
ad to early diagnosis and curative resection. Copyright (C) 2000 by W.B. Sa
