title: Spontaneous involution of pilocytic astrocytoma in a patient without neurofibromatosis type 1: case report.
abstract: Serial magnetic resonance imaging findings are described in a patient with a sporadically occurring pilocytic astrocytoma that underwent spontaneous regression over 6 years. To the authors' knowledge, this is the first report in which spontaneous involution of a pilocytic astrocytoma not associated with neurofibromatosis type 1 has been described. A literature review regarding sporadic and syndrome-associated pilocytic astrocytoma was undertaken, with particular reference to treatment and natural history.
