Intraosseous cavernous hemangioma of parietal bone: A case report and literature review

Abstract

Introduction and background: Intraosseous Hemangiomas or Primary Intraosseous Hemangiomas (PIH) are slow-growing innocuous blood vessel tumors that make up less than 1% of all bone malignancies [1]. These lesions are estimated to account for 0.2 percent of all benign skull tumors [4], with a clear female predisposition (3:1) [2]. Prior trauma to the region is thought to be the most prevalent cause of intraosseous hemangiomas. They bleed profusely when removed or biopsied; therefore, preoperative diagnosis of the lesion’s vascular character is critical [8]. They are most frequently seen in the vertebral skeleton, although they can also be found in the calvarium and facial bones. The temporal bone is the most prevalent place in the head after the vertebral skeleton, followed by the parietal, mandible, malar, and zygomatic areas [8]. In this case report, we discuss the case of a 9-year-old male who presented with a large soft mass in his right parietal region.
