Extra-Axial Cerebello-Pontine Angle Medulloblastoma in an Infant: A Rare Case Report with Review of Literature

Area of Science:

• Pediatric neuro-oncology
• Neurosurgery
• Pediatric pathology

Background:

• Medulloblastoma typically presents as an intra-axial cerebellar mass in children.
• Extra-axial medulloblastoma in the cerebellopontine angle (CPA) is exceptionally rare, with limited reported cases.
• Infantile cases of extra-axial CPA medulloblastoma are exceedingly uncommon.

Purpose of the Study:

• To report a rare case of an 8-month-old infant with an extra-axial CPA medulloblastoma.
• To discuss the diagnostic and management strategies for this rare presentation.
• To contribute to the limited literature on infantile extra-axial CPA medulloblastoma.

Main Methods:

• Case report presentation.
• Review of relevant medical literature.
• Discussion of clinical presentation, diagnostic imaging, and treatment approaches.

Main Results:

• An 8-month-old infant presented with an extra-axial CPA medulloblastoma.
• The case highlights the rarity of this tumor location and age group.
• Management strategies were considered based on available literature and clinical findings.

Conclusions:

• Extra-axial CPA medulloblastoma, though rare, can occur in infants.
• Early diagnosis and tailored management are crucial for favorable outcomes.
• Further case reports are needed to better understand this rare pediatric brain tumor.
