Pediatric cerebral proliferative angiopathy presenting infratentorial hemorrhage

Area of Science:

• Neurology
• Vascular Malformations
• Pediatric Neurology

Background:

• Cerebral proliferative angiopathies (CPAs) are distinct vascular malformations, differing from arteriovenous malformations (AVMs).
• CPAs typically present in young females with seizures, headaches, or neurological deficits; hemorrhage is rare.
• Pediatric cases of CPA are exceptionally uncommon.

Observation:

• This case report describes a child diagnosed with CPA who presented with a cerebellar bleed.
• The child received medical management for the condition.
• Follow-up imaging at 18 months showed no change in the caliber of the affected vessels.

Findings:

• The case highlights a rare pediatric presentation of CPA with cerebellar hemorrhage.
• Medical management was effective in stabilizing the vascular malformation in this pediatric patient.
• The study reviews existing literature on pediatric CPA presentations and management.

Implications:

• This case expands the understanding of CPA presentations in pediatric populations.
• It underscores the potential for medical management in pediatric CPA with hemorrhage.
• Further research into rare pediatric vascular malformations like CPA is warranted.
