[Peduncular hallucination in brain stem cavernous angioma: a case report]

Area of Science:

• Neurology
• Neurosurgery

Background:

• Cavernous angiomas are vascular malformations that can occur in the brainstem.
• Peduncular hallucinations are rare visual disturbances associated with brainstem lesions.

Observation:

• A 68-year-old man presented with left-sided sensory disturbance and developed vivid, formed visual hallucinations.
• Magnetic Resonance Imaging (MRI) identified a right brainstem cavernous angioma with surrounding hematoma.

Findings:

• The patient experienced resolution of hallucinations by the 10th hospital day.
• Surgical resection of the cavernous angioma and hematoma led to improvement in ocular movement and left-sided sensory deficits.

Implications:

• This case highlights the association between brainstem cavernous angiomas and peduncular hallucinations.
• Surgical intervention can be effective in managing neurological deficits associated with brainstem cavernous angiomas.
