BACKGROUND
Cavernous hemangioma (CH) of the bone is a rare, benign neoplasm found usually in the vertebral body. This tumor rarely develops in the calvaria, with predilection to occur in the frontal and temporoparietal bones.
CASE DESCRIPTION
A 56-year-old man with a right frontal palpable mass was admitted to our hospital. Magnetic resonance imaging (MRI) revealed a large extra-axial tumor in the right frontal bone. Intraoperatively, the bony mass involved the multilayers composed of extracranium-skull-dura-intradura-cortex. Pathologic examination revealed a typical calvarial CH penetrating dura mater.
CONCLUSIONS
This is the second reported case of calvarial CH with complete erosion of the dural plane and extension into subdural space. Although surgical resection is generally safe and easy, the possibility of dural invasion should be kept in mind for safe resection of calvarial CH, especially overlying the eloquent brain area.
背景
骨海绵状血管瘤（CH）是一种罕见的良性肿瘤，通常发生在椎体。这种肿瘤很少发生在颅骨，好发于额骨和颞顶骨。
病例描述
一名 56 岁男性因右侧额部可触及肿块而入院。磁共振成像（MRI）显示右侧额骨有一个大的颅外肿瘤。术中发现骨肿块累及由颅外-颅骨-硬脑膜-脑皮质组成的多层结构。病理检查显示典型的颅骨 CH 穿透硬脑膜。
结论
这是第二例颅骨 CH 完全侵蚀硬脑膜平面并延伸至硬脑膜下腔的报道病例。尽管手术切除通常是安全且容易的，但对于颅骨 CH 的安全切除，尤其是在脑功能区上方，应注意硬脑膜侵犯的可能性。
