Skeletal cavernous hemangiomas of the frontal bone with orbital roof and rim involvement

Abstract

Skeletal cavernous hemangiomas are rare, benign tumors that may involve the supraorbital rim and orbital roof. However, such involvement is extremely rare. We report a case of skeletal cavernous hemangioma of the frontal bone involving the orbital roof and rim. En bloc excision and reconstruction, using a calvarial bone graft for the orbital roof and rim defect, was performed. It is important not only to perform total excision of skeletal cavernous hemangiomas, but to properly reconstruct the defects after the total excision since several complications can arise from an orbital roof and rim defect.

Removal of intraosseous hemangioma in frontal bone under direct vision through a small incision

“…Osteoma is most commonly suspected in cases of firm and immobile forehead masses. However, the possibility of various pathologies other than osteoma, such as intraosseous hemangioma, fibrous dysplasia, Langerhans cell histiocytosis, multiple myeloma, meningioma, eosinophilic granuloma, and metastatic carcinoma, must also be considered [ 4 ]. Preoperative CT is essential for making an accurate preoperative differential diagnosis, planning for precautions, and establishing a surgical plan that can minimize postoperative complications [ 6 , 7 ].…”

“…Intraosseous hemangioma usually occurs in the vertebral column or, rarely, in the calvarium; in the latter, it occurs in the parietal bone, followed by the frontal bone [ 3 ]. The cause of intraosseous hemangioma has not yet been clarified, but it is reportedly related to previous trauma history [ 3 , 4 ].…”
