The authors present a preliminary experience with ethyl-enevinylalcohol copolymer (Onyx) for hemangioblastoma vessel embolization before surgical resection. The patient presented with neck pain, dizziness, blurred vision, vomiting, and loss of balance. Diagnostic imaging revealed a posterior fossa cystic mass with a nodular component. Angiography demonstrated a significant vascular blush with arteriovenous shunting that was characteristic of a hemangioblastoma. Tumor vessels originating off the left posterior inferior cerebellar artery were embolized before surgery using Onyx 18 (ev3, Covidien Vascular Therapies, Mansfield, MA, USA). This resulted in complete obliteration of all tumor vessels, transforming a highly vascular tumor into an avascular mass. A safe and uneventful surgical resection was performed the next day. Onyx is a valuable embolic agent for preoperative hemangioblastoma vessel embolization. Because of its low viscosity, Onyx penetrates deeply into the tumor vasculature and allows complete obliteration of tumor vessels. Risks of the intervention have to be carefully weighed against the benefits. If preoperative embolization is indicated, the use of Onyx should be strongly considered.

We present a case of an atypical clival meningeal melanoma treated with a multidisciplinary staged transcrusal and transsphenoidal endoscopic surgical approach. A 45-year-old woman presented with a 15-month history of visual symptoms, neck pain, and unsteadiness. Magnetic resonance imaging of the head revealed a clival mass with both intracranial and extracranial involvement. Endoscopic clival biopsy suggested a melanocytic tumor. Extensive imaging and dermatological workup did not demonstrate a primary source. A multidisciplinary staged surgical resection included a transcrusal approach to resect the intracranial component, followed by transsphenoidal endoscopic resection of the extracranial component. Postoperatively, she received adjuvant radiation. At 1 year following surgery, the patient retains full preservation of hearing, facial nerve function, and extraocular movements. To our knowledge, this is the first case report of a combined surgical approach for a primary clival meningitic melanoma.

Ganglioneuromas rarely occur in the retropharynx with only three cases reported in the current literature. The most common symptom associated with retropharyngeal ganglioneuromas is dysphagia. We report a retropharyngeal ganglioneuroma with an unusual clinical presentation of neck stiffness and pain. A 42-year-old woman presented with incapacitating neck pain, neck stiffness, right upper extremity weakness, as well as dysphagia. Neurological workup was normal. Imaging revealed a hyperdense, ill-defined, diffuse right retropharyngeal mass suggestive of a possible nerve sheath tumor with no communication with the cervical spine. Surgical removal was uneventful and associated with a postoperative Horner's syndrome. In follow-up, dysphagia and neck symptoms improved. Retropharyngeal ganglioneuromas can occur in a wide age range of patients. Surgical excision via a cervical approach offers definitive therapy but may be associated with an iatrogenic Horner's syndrome for which the patients should be counseled prior to operative intervention. Neck pain is an atypical symptom that needs to be worked up to rule out a communication with the spinal column prior to surgical removal. Patients must be counseled that atypical symptoms may not completely resolve with surgical treatment.

Ectopic recurrence of craniopharyngioma 17 years after initial diagnosis is exceedingly rare in pediatric neuro-oncology. Only 23 cases of ectopic recurrence in children with craniopharyngioma are described in the literature with a median time to recurrence of 3 years. We describe a patient diagnosed at 5 years of age, presenting with neck pain and ataxia 17 years after diagnosis. Her original follow-up care was fragmented and included surveillance imaging for 10 years after surgery and endocrine management of panhypopituitarism. Rare, extremely late relapse of this tumor highlights the importance of extended multidisciplinary follow-up care that includes neuro-oncologists in a late-effects/survivorship program.

Surgical therapy of cervical spine metastases had evolved a in the last years from posterior decompressive approaches to a direct anterior reconstructive approaches. Indication for surgery included intractable neck pain, spinal cord compression and stabilization of impending pathological fractures. We report our experience with expandable cylindrical cages in order to reconstruct and to stabilize cervical spine with metastasis. Between June 2004 and January 2006, a consecutive series of six patients underwent to resection of metastatic tumor in the cervical spine followed by expandable cylindrical cage reconstruction of the anterior vertebral column. All patients achieved immediate stability with neurological preservation. There were no significant complications related to the expandable cages in a mean follow up period of 10.5 months. Expandable cylindrical cages are effective resources for functional reconstruction after tumor resection in patients with cervical metastasis with advantages in the quality of life.

We present a first case of concurrent tumors consisting of schwannoma and meningioma arising at the same spinal level in a patient without neurofibromatosis. A 49-year-old man without clinical evidence of neurofibromatosis presented with a 5-month history of right neck pain. MRI demonstrated an extradural tumor involving the right-sided C2 nerve root with a small intradural component. T1- and T2-weighted and contrast-enhanced MRI could not differentiate the intradural tumor as different from the extradural tumor. Total removal of the tumors was performed. No contiguity of the extradural tumor with the intradural tumor was seen. The intradural tumor attached strongly to the dura mater around the C2 nerve root exits. Intraoperative pathological diagnosis confirmed the extradural tumor as schwannoma and the intradural tumor as meningioma. We therefore thoroughly coagulated the dura mater adjacent to the intradural tumor and resected the dura mater around the nerve root exits together with the tumor. Pathological examination revealed that the resection edge of the extradural component consisted of a spinal nerve with thickened epineurium and was free of neoplastic cells. No schwannoma component was evident in the intradural tumor. No obvious transition thus existed between the extra- and intradural tumors. Distinguishing these tumors prior to surgery is critical for determining an optimal surgical plan, as schwannoma and meningioma require different surgical procedures. We therefore recommend a careful review of preoperative imaging with the possibility of concurrent tumors in mind.

We report a patient with Villaret's syndrome (left hypoglossopharyngeal nerve, vagus nerve, accessory nerve, and hypoglossal nerve palsies and left Horner's sign) caused by internal carotid artery dissection. He had neck pain on the left side, Horner's sign on the left side and paralysis of the left hypoglossopharyngeal nerve, vagus nerve, accessory nerve, and hypoglossal nerve. Brain MRI revealed no signal from the left internal carotid artery and no brain infarction, although a tumor-like lesion was observed in the left internal carotid artery. Subsequent MRI studies revealed intramural hematoma in the left internal carotid artery, and on the basis of this finding, he was diagnosed with internal carotid artery dissection. He received anticoagulant and antiplatelet therapy. His symptoms improved gradually. The symptoms of internal carotid artery dissection are neck pain, Horner's sign, brain infarction, and lower cranial nerve palsy. A characteristic feature in this case was that brain infarction was not observed. Only 3 similar cases have been reported in the past In all these cases, the patients had a good clinical course and showed complete recovery from the symptoms. Compared with western countries, in Japan, carotid artery dissection is rare. Carotid artery dissection should be considered as a differential diagnosis of lower cranial nerve palsy.

Intradural extramedullary (IDEM) ependymomas occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 57-year-old woman with an IDEM ependymoma. She was referred for the evaluation of a 4-month history of increasing neck pain and muscular weakness of the left extremities. Magnetic resonance imaging (MRI) of the cervical spine demonstrated an IDEM tumor with spinal cord compression. At the time of surgery, an encapsulated IDEM tumor without a dural attachment or medullary infiltration was noted, but the tumor capsule adherent to the spinal cord and root was left in place to minimize the risk of neurological sequelae. Histologic examination revealed a benign classic ependymoma. The post-operative course was uneventful and radiotherapy was performed. The patient showed an excellent clinical recovery, with no recurrence after 5 years of follow-up.

Giant cell tumors (GCTs) are rare lesions of the cervical spine, with only 14 previously reported pediatric cases in the literature, all occurring in females. The authors present the case of a 15-year-old boy with neck pain who was found to have a lytic GCT of the odontoid process. Following resection, recurrent disease was treated with radiotherapy and chemotherapy and then a final resection. He has remained tumor free for more than 10 years. The rarity of GCTs can make their diagnosis difficult in the cervical spine. Because of their aggressive behavior and relative resistance to adjuvant therapy, GCTs must be monitored diligently and treated aggressively.

The purpose of this paper was to inform the reader that prolonged upper airway obstruction after posterior cervical spine surgery is a possible complication for patients with metastatic tumor of upper cervical spine. A 49-year-old man presented severe neck pain during posture changes due to metastatic spinal tumor of C2. Occipitocervical fusion following removal of the posterior arch of C1 and laminectomy of C2 via the single posterior approach was performed 2 weeks after radiation therapy. After the surgery, life-threatening airway obstruction due to pharyngeal oedema occurred immediately after extubation that required emergency tracheostomy. The airway obstruction did not improve well during the patient's postoperative course. Once pharyngeal oedema occurs in patients with metastatic tumor of upper cervical spine who undergo posterior cervical spine surgery following radiation therapy to the neck, the pharyngeal oedema may be constant for a long period of time.
