title: A case of calvarial hemangioma in cranioplasty site.
abstract: It is not uncommon for hemangiomas to occur in the calvarium, accounting for about 10% of the benign skull tumors. A 46-year-old man was presented with a palpable scalp mass on the left parietal region. Past medical history indicated that he had undergone cranioplasty 25 years prior due to a depressed skull fracture suffered from a traffic accident. Magnetic resonance imaging revealed mixed signal intensity mass on T1 -and T2-weighted images pushing a linear signal void lesion outward in the left parietal region. After total surgical removal along with cranioplasty, he was discharged without neurological deficits. Histological examination of the surgical specimen revealed a cavernous hemangioma. A skull hemangioma occurring at the site of a cranioplasty has not yet been reported. Therefore, authors report this case in combination with a pertinent literature review.
