title: Expanding septum pellucidum cyst due to a traumatic ventriculoperitoneal shunt.
abstract: A rare complication of a ventriculoperitoneal (VP) shunt is reported. Serial imaging studies demonstrated the formation of an expanding septum pellucidum cyst after an indwelling shunt tube penetrated the wall of the septum pellucidum. This complication should be borne in mind if patients have symptoms of intermittent obstructive hydrocephalus or related to pressure effects from the septum pellucidum after VP shunting.
