Primary Intraosseous Cavernous Hemangioma of the Clivus: Case Report and Review of the Literature

Abstract

Primary intraosseous hemangiomas are benign, vascular malformations that account for approximately 1% of all primary bone neoplasms. These tumors are mostly found in vertebral bodies and are rarely seen in the calvarium, where they represent 0.2% of bony neoplasms. When found in the skull, they tend to present with vague symptoms and do not have the typical radiological findings suggestive of hemangiomas. Because of this, these tumors can be missed in many cases or may be misinterpreted as more ominous lesions like multiple myeloma or osteosarcoma. Involvement of the skull base is exceedingly rare, and presentation with cranial nerve unilateral polyneuropathies has not been reported. We report a patient case with review of recent pertinent literature.

Petroclival intravascular papillary endothelial hyperplasia with psammoma body‐like structures

“…Considering all the reported cases of hemangiomas and IPEH of the petrous bone and the clivus plus our case, 18 out of 23 cases (78%) belonged to women, whereas only five out of 23 (22%) belonged to men . Seventeen out of 20 patients (85%) were older than 17 years at diagnosis, and median age at diagnosis was 49 years. Median age at diagnosis was higher in patients with clival hemangiomas and IPEHs compared to patients with petrous bone hemangiomas and IPEHs, 61 and 42 years, respectively.…”

“…Seventeen out of 20 patients (85%) were older than 17 years at diagnosis, and median age at diagnosis was 49 years. Median age at diagnosis was higher in patients with clival hemangiomas and IPEHs compared to patients with petrous bone hemangiomas and IPEHs, 61 and 42 years, respectively. Symptoms were different in clival hemangiomas and petrous bone hemangiomas.…”

Congenital Intraosseous Cavernous Hemangioma of the Skull: An Unusual Case

“…Trauma has not been thought to be a predisposing factor [1,5]. These tumors are mostly found in vertebral bodies and are rarely seen in the calvarium [6]. The usual age of presentation is the 2nd to 4th decades of life.…”

Benign and malignant diseases of the clivus

“…Lymphomas, 36e38 giant cell tumours, 39 Langerhan's cell histiocytosis, 40e43 and intra-osseous haemangiomas 44 of the clivus are rare, having been reported as case reports. The lesions are reported as showing strong enhancement except for giant cell tumour, which is moderately enhancing.…”
