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.
Insights
Peduncular hallucinations are typically linked to intrinsic midbrain lesions. This case report details a 16-year-old boy whose hallucinations resolved after a medulloblastoma compressing the midbrain was surgically removed.
Area of Science:
- Neurology
- Neuro-oncology
- Ophthalmology
Background:
- Peduncular hallucinations are rare visual disturbances.
- They are usually associated with intrinsic lesions within the midbrain.
- Previous literature predominantly links these hallucinations to structural abnormalities within the midbrain itself.
