Background:
Congenital hemangiomas are benign vascular tumors, and the intracranial counterpart was described in very few cases.
Case description:
A newborn presented with an intracranial tumor associated with an arachnoid cyst, diagnosed by antenatal ultrasound at 37 weeks of gestation. Surgery was indicated due to increased head circumference and bulging fontanelle, and a complete resection of an extra-axial red-brown tumor was performed at the 3(rd) week of life. Microscopy revealed a hemangioma.
Conclusion:
Hemangioma is a rare differential diagnosis that must be considered in extra-axial intracranial tumors affecting infants and neonates. The radiological features are not helpful in differentiating from other tumors, and surgery is indicated when the diagnosis is uncertain or whenever there are signs of increased intracranial pressure.
