BackgroundCavernous hemangiomas arising in the extraaxial space are rarely encountered, often mimicking other more common pathologies. Furthermore, multiple coexisting lesions and posterior fossa involvement are scarcely reported. Herein, we present the case of a patient with concurrent frontal bone and posterior fossa extraaxial cavernous hemangiomas. We also review the challenges associated with the diagnosis and management of these entities.Case DescriptionAn otherwise healthy 41-year-old gentleman presented with a 7-month history of a progressive right forehead mass. Imaging demonstrated a right frontal bone mass and an incidentally noted transverse sinus-based mass. The patient opted for surgical resection of both lesions. A right frontal craniotomy was performed to remove the bony lesion, followed by a suboccipital approach for the dural-based mass. There were no significant complications intraoperatively, and gross total resection was achieved for both lesions. Final pathology for each was consistent with cavernous hemangioma.ConclusionsExtraaxial cavernous hemangiomas are uncommon clinical entities that are challenging to distinguish from other diseases. If intraoperative complications can be avoided, treatment with surgical resection often offers excellent patient outcomes.Copyright © 2019 Elsevier Inc. All rights reserved.
