Case Discussion
Case findings are consistent with skull vault haemangioma (also known as cavalrial haemangioma).
Learning points:
- skull vault haemangiomas are benign, indolent vascular neoplasms affecting the skull diploë, with frontal and parietal bones commonly implicated
- CT findings consistent with skull vault haemangioma include:
- expansile bone lesion with thin borders
- "sun-ray/burst" pattern of trabecular internal striation radiating from a common centre
- management may involve radiotherapy, surgical resection, and/or embolisation
