Hemangioma calcificans in the fourth ventricle

Area of Science:

• Neurology
• Neurosurgery
• Radiology

Background:

• Hemangioma calcificans is a rare vascular tumor.
• Fourth ventricle tumors can cause obstructive hydrocephalus.

Observation:

• A patient presented with symptoms of increased intracranial pressure.
• Skull X-rays showed dense calcification in the posterior fossa.
• CT scans revealed a hyperdense mass within the 4th ventricle.

Findings:

• The mass was diagnosed as hemangioma calcificans.
• Obstructive hydrocephalus was confirmed as the cause of symptoms.
• Surgical resection of the tumor was performed.

Implications:

• This case highlights the importance of considering rare tumors in the differential diagnosis of posterior fossa masses.
• Successful surgical management of 4th ventricle hemangioma calcificans is demonstrated.
• Advanced imaging techniques like CT are crucial for diagnosis.
