title: Shunt metastases of pineal tumors presenting as a pelvic mass.
abstract: Three children with pineal area tumors and ventriculoperitoneal shunts developed pelvic masses. In two, the solid masses reflected tumor cells seeded to the Pouch of Douglas while the third developed a loculation of fluid and tumor cells at the shunt tip.
