Surgical Management of a Massive Frontal Bone Hemangioma: Case Report

Intraosseous hemangiomas are rare, benign tumors that can arise from the calvarium. These lesions often invade the outer table of the skull, but typically spare the inner table and intracranial structures. En bloc surgical resection is the standard treatment for intraosseous hemangiomas. However, a piecemeal resection may be required to safely remove the tumor in cases involving the inner table to protect the underlying brain parenchyma and vascular structures. Proper reconstruction is critical to optimize the cosmetic outcome, and a staged procedure allowing implantation of a custom-made implant can be considered for large lesions involving the forehead. We present a case of a patient with a large frontal intraosseous hemangioma with intradural involvement to highlight the surgical nuances of resection and review the existing literature regarding optimal management of these patients.

Automated summary

Intraosseous hemangiomas are rare benign tumors that can invade the outer table of the skull but typically spare the inner layer and intracranial structures. Surgical resection is the standard treatment, with proper reconstruction critical for cosmetic outcomes. En bloc or piecemeal resection may be necessary depending on the extent of involvement.
