title: Transient peduncular hallucinations secondary to brain stem compression by a medulloblastoma.
abstract: Almost all peduncular hallucinations have been described in patients with intrinsic lesions of the midbrain. An as yet unreported case of peduncular hallucinosis caused by posterior compression of the midbrain by a medulloblastoma in a 16-year-old boy is provided. The hallucinations and associated symptoms only ceased after removal of the tumor.
