title: An unusual position of the gallbladder following nephrectomy for large neoplasms.
abstract: The cases of two children are presented in whom the gallbladder was found to lie in an unusual position in the ipsilateral renal fossa following nephrectomy for large neoplasms. This postoperative visceral position must be recognized, as the appearance on cross-sectional imaging can mimic postoperative fluid collections at the resection site or tumor recurrence.
