CASE REPORT Intradiploic cavernous hemangioma of the skull in a child: a case report Murat Cosar & Olcay Eser & Adem Aslan & Serhat Korkmaz & Gazi Boyaci & Fatma Aktepe Received: 18 January 2008 / Published online: 23 April 2008 # Springer-Verlag 2008 Abstract Introduction Intradiploic cavernous hemangioma of the skull is seen rarely. Intradiploic cavernous hemangiomas arise from the intrinsic vasculature of the bone and generally picks up at the fourth and fifth decades. Discussion and conclusion In this report, we present a 16- year-old child who was admitted with a swelling lesion in the right parietal bone and diagnosed as cavernous hemangioma after total extirpation. Keywords Cavernous hemangioma . Child . Intradiploic . Skull Introduction Intradiploic cavernous hemangioma of the calvarium is an uncommon pathological diagnosis with an incidence of 2% in all benign skull neoplasms [1, 2, 5, 6, 8]. Intradiploic cavernous hemangiomas arise from the intrinsic vasculature of the bone and generally picks up at the fourth and fifth decades [10]. Although cavernous hemangiomas can show the feature of congenital vascular disorders, its incidence in the first and second decade is quite low. We have encountered a few children cases of intradiploic cavernous hemangioma of the skull in the English literature [3, 13]. We present a child patient with an intradiploic cavernous hemangioma at the right parietal bone. Case report A 16-year-old child was admitted to our neurosurgery department with a complaint of painless swelling lesion on the right part of his calvarium skull that had developed in the previous 3 months. There were no relevant items in his personal or family story. Physical examination revealed a solid, nonpulsatile mass in the right parietal region. The neurological examination and laboratory tests were normal. Direct graphics of the skull showed a lytic hypodense area in the right parietal region. Bone window computerized tomography (CT) revealed an intradiploic mass with a size of 1×1×1 cm in the right parietal bone (Fig. 1a, b). The advice of surgical resection of the mass was rejected by the patient. After 2 months, the patient was admitted to our emergency department with severe headache and swelling on the right parietal region. The cranial CT showed the increased size of the mass (2×2×2 cm) as compared the previous one. T1-weighted magnetic resonance imaging (MRI) showed nonhomogenously isointense mass and contrast enhancing while T2-weighted MRI revealed a heterogenous hyperintense images (Fig. 2a, b). Surgical resection of the mass was planned. Right parietal skin flaps and craniotomies were performed. The Childs Nerv Syst (2008) 24:975–977 DOI 10.1007/s00381-008-0638-0 M.
