We report the first use of Onyx in the embolization of spinal tumors in 2 cases of aggressive vertebral hemangioma. In both cases, Onyx embolization provided effective preoperative tumor devascularization after the initial prolonged particulate embolization with Embospheres made little overall impact. Onyx enables a more rapid and visible embolization than particles and is less technically dema...

BACKGROUND Vertebral hemangiomas are benign tumors with a rich vasculature. Symptoms may vary from simple vertebral pain, sometimes resistant to conservative medical treatment, to progressive neurological deficit. Surgery or radiotherapy have been the treatment of choice for several years, but they were worsened by intraoperative and postoperative hemorrhagic complications related to the rich v...

Intraosseous hemangiomas are uncommon, constituting less than 1% of all osseous tumors. The most frequent sites are the calvaria and the vertebral column. Involvement of the facial bones is rare, and occurs most commonly in the maxilla, mandible, and nasal bones. Only 20 cases of zygomatic involvement have been reported in the English-language literature. We report a case of an intraosseous hem...

Three cases of spinal epidural hematoma are presented. Computed tomography (CT) was the first diagnostic method used in two patients and demonstrated a surgically confirmed spinal epidural hematoma in both patients. In a third patient who presented with a complete block on myelography, CT was helpful in assessment of the extent of the lesion and suggested a vertebral hemangioma as the cause of ...

Intraosseous hemangiomas account for 1% of all bone tumors and primarily originate from the vertebral column and skull bones. However, intraosseous hemangiomas of the nasal cavity are extremely rare. Here, we report a case of intraosseous hemangioma with a cavernous pattern arising from the middle turbinate that was preoperatively misdiagnosed as chronic rhinosinusitis with polyps. Except for n...

Cavernous hemangiomas are uncommon vascular malformations of the CNS that may affect any part of the neuroaxis. Most of these lesions are intracranial; supratentorial sites are most common [1]. In the spine, lesions of the vertebral bodies are most common, intramedullary [2] and intradural extramedullary [3] lesions of the spinal axis are uncommon, and purely epidural lesions are rare [4, 5]. W...

A 2-year-old girl presented with cutaneous facial, palpebral, back, perianal, and perineal hemangiomas and a subcutaneous neck and parotid voluminous hemangioma, associated with several extracranial vascular abnormalities, such as the absence of the ipsilateral internal carotid artery and hypoplasia of the common carotid arteries. Both vertebral arteries showed an embryonic appearance, without ...
