Intraosseous anastomosing haemangioma of the skull: a case report

Anastomosing haemangiomas are rare benign vascular tumours. Their occurrence within the skull is exceptionally rare, with few documented cases in the literature.

We present a case of a large intraosseous anastomosing haemangioma arising from the skull vault with associated neurological symptoms. A 30-year-old male presented with transient right-sided hemiparesis and dysarthria lasting approximately 30 minutes. Neuroimaging revealed a large extra-axial mass in the left frontoparietal region causing local mass effect. The patient underwent simultaneous craniotomy and gross total resection of the tumour and cranioplasty. The final histopathological diagnosis was an anastomosing haemangioma. The patient recovered well postoperatively and has had no further neurological symptoms during follow-up.

This case highlights the rare presentation of an intraosseous anastomosing haemangioma of the skull with neurological manifestations. Complete excision remains the treatment of choice. Margin involvement necessitates close follow-up. Consideration of this rare entity in the differential diagnosis of vascular bone tumours of the skull is important in neurosurgical practice.
