顱骨海綿狀血管瘤是一種罕見的良性腫瘤，可能被診斷為其他顱骨溶骨性病變， 例如骨肉瘤或多發性骨髓瘤。在此，我們報告一名32 歲男性在左前額有一變大無痛的 腫塊，電腦斷層掃描顯示此腫塊為左前額顱骨溶骨性病變。病患接受客制化顱骨病灶全 切除及鈦金屬網片的顱骨整型手術治療，最後病理學檢查證實了海綿狀血管瘤的診斷。

Calvarial cavernous hemangioma is a rare benign tumor that may mimic other cranial osteolytic lesions, such as osteosarcoma or multiple myeloma. We report a case of a 32-yearold man who presented with a painless frontal mass and associated enlargement. A computed tomographic scan showed an osteolytic lesion in the left frontal region. A tailored craniectomy followed by cranioplasty with a titanic mesh was performed, and a pathological study confirmed the diagnosis of cavernous hemangioma.
