Tentorial cavernous angioma with calcification in a neonate

Area of Science:

• Neuroscience
• Pediatric Neurosurgery
• Medical Imaging

Background:

• Cavernous angiomas are vascular malformations that can occur in the brain.
• Intracranial hemorrhage in neonates is a serious condition requiring prompt diagnosis.
• Prenatal diagnosis of brain abnormalities is increasingly feasible with advanced imaging.

Observation:

• A neonate presented with a cavernous angioma of the tentorium cerebelli, detected via serial ultrasonography.
• The tumor was associated with a calcified expansive hematoma in the posterior fossa.
• The calcified hematoma was visible on a conventional skull X-ray at birth.

Findings:

• Total surgical extirpation of the cavernous angioma was achieved without significant neurological deficit.
• This represents the first reported case of surgically treated and histologically verified cavernous angioma in a neonate.
• It is also the first reported case of a calcified hematoma revealed by conventional skull X-ray in a neonate.

Implications:

• Intracranial cavernous angiomas can hemorrhage early in life, potentially even prenatally.
• Early diagnosis and surgical intervention are crucial for managing intracranial cavernous angiomas in neonates.
• This case underscores the utility of advanced imaging techniques in identifying congenital brain abnormalities.
