Abstract
OBJECT Published data obtained in children with tumors of the skull base are sparse. In the majority of the available reports, the authors focus on the technical application of skull base approaches, but they contribute a paucity of information on the management of specific tumors, especially malignant skull base lesions. The purposes of this report are to increase the collective experience with the treatment of these tumors and to identify successful management paradigms. METHODS The authors retrospectively reviewed the clinical records, pathological reports, and diagnostic images obtained in 24 children (< or = 19 years of age) with tumors arising from the cranial base in whom resection was part of their management between 1992 and 2002. Surgery-related complications and outcomes were analyzed with regard to tumor type and surgical approach. The median age of the group was 14 years. Tumors involved the anterior skull base in eight (33%), the middle skull base in 10 (42%), both the anterior and middle skull base in four (17%), and the posterior skull base in two patients (8%). Benign lesions were discovered in 11 patients (46%) and malignant neoplasms in 13 (54%). The tumors were most commonly of mesenchymal origin (21 [87.5%] of 24 tumors). Thirty surgical procedures were performed using a number of skull base approaches. A gross-total resection was achieved in 23 procedures (77%) and a subtotal resection in five (17%); a biopsy procedure was performed in one case; and the disease process could not be accessed in one case. One patient died in the perioperative period. Minor complications (Karnofsky Performance Scale score > or = 90, no prolongation of hospital stay, and no further surgery needed) occurred following 10 (33%) of the 30 surgical procedures. These affected 10 (42%) of the 24 patients and resulted in persistent or prolonged deficits in only five patients (21%). In nine patients (38%) the tumor recurred after a mean duration of 23 months. CONCLUSIONS Skull base tumors in children affect mainly the anterior and middle cranial fossa. Sarcomas account for the majority of malignant tumors. Treatment of skull base tumors in children and adolescents needs to be tailored to patient age, tumor location, and tumor type.

Abstract
OBJECTIVE To evaluate the clinical features and incidence of true myxomas affecting the lateral skull base. MATERIAL AND METHODS Illustrative case report and review of the relevant literature. Included are all reports of myxomas according to the histopathologic definition of Stout. RESULTS Despite nine case reports, only four patients matched the histopathologic criteria of a true myxoma growing in the lateral skull base. Facial palsy occurred in three adults with additional otalgia in one and progressive hearing loss (HL) in another patient. Our patient initially presented with signs of recurrent otitis media. The mastoid cavity was involved in all patients. CONCLUSION Differential diagnosis of lesions occurring in the lateral skull base should include true myxoma. Correct diagnosis should be based on immunohistopathology to rule out malignant tumors. Radical surgery is the treatment of choice, but surgeons should respect vital structures and esthetic consequences.

Abstract
A 55-year-old man presented with esthesioneuroblastoma in the right paranasal sinuses and orbita, extending into the right anterior and middle cranial fossa. He received a partial resection of tumour and post-operative radiotherapy, which was set with a central focus on the right orbit. Five years later, he came to our hospital with a complaint of left exophthalmos. Neuro-imaging revealed that the tumour recurred on the opposite side of the primary lesion, which was out side the irradiated field, with progressive invasion of the left temporal dura. The residual tumour in the irradiated field had reduced in size. He received gross total resection and post-operative radiotherapy. We would like to emphasize that radiotherapy is an important adjuvant therapy for esthesioneuroblastoma, and that the field setting for radiation therapy is extremely important.

Abstract
Patients presenting with neck complaints, such as pain or stiffness, are not uncommon in the Emergency Department. Complaints of neck instability, however, are unusual. We report the case of a 30-year-old woman who presented with multiple neck complaints that included having a "wobbly" sensation of her neck on flexion, feeling as if it were unstable. Our patient indeed had atlanto-occipital instability secondary to a locally destructive tumor of the cranial base, known as a clival chordoma. Chordomas are rare and unique bony tumors that arise along the neural axis and are thought to originate from the nucleus pulposus. The tumors are slow growing; locally invasive; and cause a variety of neurologic, musculoskeletal, cranial, and neck complaints. We describe this unique case and its presentations in an attempt to increase the sensitivity of physicians in early detection of this rare and lethal tumor.

Abstract
BACKGROUND Cranial nerve lesions due to metastases from prostate carcinoma to the skull base are an uncommon yet clinically significant finding. METHODS The authors report the clinical features, treatment, and outcomes for 15 patients who presented with cranial nerve palsies complicating metastatic prostate carcinoma. Patient charts identified from a Fox Chase Cancer Center treatment data base were reviewed. RESULTS All patients had hormone-refractory disease at the time of symptom onset. Twelve of 15 patients had received prior chemotherapy, and 13 of 15 patients had received prior radiation therapy to areas of bony pain. Symptoms varied from recognized clinical syndromes involving multiple cranial nerves to isolated cranial nerve lesions. All patients had lesions at the skull base that were visualized on computed tomography scans or magnetic resonance images. All patients were treated with palliative radiation therapy to either the whole brain or the skull base. Fourteen of 15 patients had a clinical (either partial or complete) response to radiation therapy. All responding patients subsequently died of prostate carcinoma without worsening of residual or development of new cranial nerve symptoms. Ten of 15 patients (67%) died within 3 months of developing symptoms, and the remaining 5 patients lived between 9 months and 31 months from onset of symptoms. CONCLUSIONS The authors concluded that palliative radiation therapy should be considered in this heterogeneous group of patients given the potential for significant symptom improvement.

Abstract
A 36-year-old man presented with a tumor in the anterior skull base manifesting as headache and visual disturbance. Neurofibromatosis type 1 (NF-1) was identified in early childhood in the patient, and also in his father. Subtotal excision of the tumor was performed, leaving the portion extending outside of the cranium. The histological diagnosis was malignant peripheral nerve sheath tumor. Local radiotherapy was instituted postoperatively. Facial paralysis and dysphagia appeared 7 months after the first operation. Magnetic resonance imaging revealed new lesions in the lateral ventricle and around the brainstem. These tumors were also subtotally excised, but the patient died 10 months after the first operation. The tumor very likely originated from the meningeal branch of the trigeminal nerve. Treatment of such tumors developing inside the cranium should include the widest resection possible, followed by irradiation of the entire neuraxis including the spinal cord to inhibit dissemination through the cerebrospinal fluid. Treatment should be started as quickly as possible if the tumor is associated with NF-1, because of the poor prognosis associated with this condition.

Abstract
Meningiomas are the most frequent benign tumors treated by gamma knife radiosurgery and the majority of them are located on the skull base. Between 1992 and 1999, 197 skull base-located meningiomas in 192 patients were treated by gamma knife in Prague. Contact with the chiasma or optic tract was not regarded as a contraindication for gamma knife radiosurgery and such contact was observed in 32% of the skull base meningiomas treated. 176 patients were monitored during a median of 36 months, of whom 73% showed a decrease in tumor volume; no change was observed in 25% and continued growth was observed in 2%. Neurodeficit improved in 63% of patients, temporary morbidity occurred in 11% and persistent morbidity remained in 4.5%. Radiosurgery induced edema in 11%. Significantly lower edema occurrence was observed after radiosurgery in patients with no history of edema prior to radiosurgery, where the tumor was located in the posterior skull base and where the dosage to the tumor margin was lower than or equal to 14 Gy. Radiosurgery of skull base meningiomas has been proven to be safe and efficient. We consider gamma knife treatment for skull base meningiomas to be the method of choice whenever tumors are within the volume limits and there is no need for an urgent decompressive effect from the open operation.

Abstract
PURPOSE To investigate prognostic values of nasopharyngeal carcinoma (NPC) with skull base invasion for optimal management, according to its extent of involvement. METHODS From January 1985 through December 2000, 119 patients with histologically proven NPC were analyzed retrospectively with review of their computed tomography/magnetic resonance imaging and medical records. All patients underwent sequential chemoradiotherapy except 2 cases, which were treated concurrently. The mean duration of follow-up was 61 months (range 8-179). Potential prognostic factors were evaluated by univariate and multivariate analyses by the Kaplan-Meier method and the Cox model, with a particular emphasis on the extent of skull base invasion. RESULTS Skull base invasion was found in 46 (38.6%) of 119 patients. Cranial nerve palsy and intracranial extension was discovered in 34 (28.6%) and 23 (19.3%) of these patients, respectively. The sole erosion of the skull base was not found to be a poor prognostic factor. Patients with involvement of both anterior (I-VIII) and posterior (IX-XII) cranial nerves had a worse prognosis than those with involvement of either anterior or posterior cranial nerves (P = 0.0219). The presence of intracranial extension was the worst prognostic factor in NPC with skull base invasion (P = 0.0269). The advanced neck stage and histology did not affect the prognosis of NPC in the presence of skull base invasion. CONCLUSION Our results show that NPC with skull base invasion should be divided into the groups with, simple skull base erosion, minimal involvement of either anterior or posterior cranial nerves, multiple involvements of both cranial nerves, and intracranial extension.

Abstract
Teratomas of the oropharynx are quite rare congenital tumors. Even more rare than oropharyngeal teratomas are those with additional intracranial extension. Reviewing the literature the prognosis of these cases has been poor. In the majority stillbirth or immediate postpartum death following respiratory obstruction is reported. We present a case of a congenital teratoma of the oral cavity with intracranial extension in a female neonate. After several intraoral tumor resections to establish secure airway in the postpartum period the total tumor resection had to be performed at the age of 6 month via a lateral transmandibular approach to the skull base. By using extraoral distaction devices the operation related microsomia of the mandible could be corrected at the age of 5 years. At 7 years follow-up the girl presented free of recurrence and without any neurological or functional deficits.

Abstract
Malignant solitary fibrous tumours (MSFTs) are rare tumours of fibrous origin, which can occur at all anatomical sites and represent 20% of solitary fibrous tumours. Fine-needle aspiration cytology is not able to distinguish benign from malignant disease, and sufficient tissue has to be obtained for accurate histological diagnosis to be made. Lesions > 10 cm in diameter and incomplete resection or non-resectability are predictive factors for poor long-term survival. We present a 57-year-old patient with a presumably metastatic MSFT from the peritoneal cavity to the skull-base who is in a stable state 17 months after surgical debulking of the skull-base and removal of the peritoneal lesion, followed by post-operative chemotherapy. We suggest the terminology metastatic malignant solitary fibrous tumour for a description of this disease.

Abstract
A thirteen-year-old boy with Ewing's sarcoma was presented. The treatment was considerably delayed because of the initial diagnostic difficulties due to its insidious presentation and the unwillingness of the child's parents to further investigations and treatment. During a three-year delay, the tumor turned out to be a gross painful mass from a painless lesion. Cranial computed tomography and magnetic resonance imaging with contrast showed a destructive lesion extensively involving the right mandible and the skull base, with invasion to the intracranial space. Facial and intratemporal portions of the mass were removed totally, but the intracranial extension could not be totally excised because of cavernous sinus involvement. Histologic and immunohistochemical findings were consistent with the diagnosis of Ewing's sarcoma. The patient received systemic chemotherapy and radiotherapy following surgery. A month after radiation therapy, radiologic investigations showed a lung mass suggestive of metastasis. He died two days after hospitalization, from an intracranial hemorrhage associated with the intracranial mass.

Abstract
Progresses of the three-dimensional imageries and of the software of planning systems makes that the radiotherapy of the tumours of brain and the base of skull is increasingly precise. The set-up of the patients and the positioning of the beams are key acts whose realization can become extremely tiresome if the requirement of precision increases. This precision very often rests still on the visual comparison of digital images. In the near future, the development of the automated systems controlled by robots should allow a noticeable improvement of the precision, safety and speed of the patient set-up.

Abstract
Lymphangiomatosis of the bone is rare. The axial as well as appendicular skeleton may be affected. Neurosurgical consultation may be called for several reasons: (1) lesions involving the calvarium and/or spine; (2) nondiagnostic biopsies from more accessible and less morbid locations, and (3) persistent CSF leak and/or recurrent meningitis. Thus, it is important for the neurosurgeon to be familiar with this disease entity and consider it in the differential diagnoses of multifocal lytic lesions of the axial skeleton. We present a case report of a 4-year-old girl with lymphangiomatosis of the skull base and upper cervical spine with concurrent Chiari I malformation and briefly review the literature.

Abstract
A 29-year-old woman presented with a primary meningeal melanocytoma of the left middle fossa manifesting as headache and nausea. Computed tomography (CT) with contrast medium demonstrated a clearly demarcated, homogeneously enhanced high density area surrounded by a cyst in the left temporal lobe. Magnetic resonance (MR) imaging showed the mass as a slightly high signal intensity area on the T1-weighted image and as a low signal intensity area on the T2-weighted image. Cerebral angiography revealed shift of the middle cerebral artery but no tumor stain. The solid part of the tumor had rapidly increased in size with reduction of the cyst 3 months later. Left frontotemporal craniotomy disclosed a clearly demarcated jet-black tumor attached to the dura. The black-colored lesion in the dura and the bone extended to the skull base, so malignant melanoma was a possibility. The solid part of the tumor was gross totally removed, and the dura and the skull bone were preserved. Histological examination of the tumor specimen revealed meningeal melanocytoma. Melanophages were present in the specimen of the black-colored lesion in the dura and the bone, but no neoplastic infiltration was present. The postoperative course was uneventful, and the patient's headache and nausea disappeared. CT and MR imaging taken 1 month later confirmed total removal of the tumor. No recurrence has been observed for 2.5 years after surgery. Preoperative differentiation of meningeal melanocytoma from malignant melanoma is difficult, but the primary goal of therapy is gross total resection of the solid part of the tumor irrespective of tumor type.

Abstract
PURPOSE To prospectively evaluate outcome and toxicity after carbon ion radiotherapy (RT) in chordomas and low-grade chondrosarcomas. PATIENTS AND METHODS Between September 1998 and December 2001, 74 patients were treated for chordomas and chondrosarcomas with carbon ion RT at the "Gesellschaft für Schwerionenforschung" (GSI). Seven patients reirradiated with reduced carbon ion doses after conventional RT were excluded from the analysis, leaving 67 evaluable patients (44 chordomas and 23 chondrosarcomas) who received a full course of carbon ion therapy. Tumor-conform application of carbon ion beams was realized by intensity-controlled raster scanning with active energy variation. Three-dimensional treatment planning included intensity modulation and biological plan optimization. A median dose of 60 GyE was applied to the target volume within 20 consecutive days at a dose of 3.0 GyE per fraction. RESULTS Median follow-up was 15 months (range 3-46 months). At 3 years, actuarial local control was 100% for chondrosarcomas and 87% for chordomas, respectively. Partial tumor remission was observed in 14/44 (31%) chordoma patients and in 4/23 (17%) chondrosarcoma patients. At 3 years, actuarial overall survival was 100% for chondrosarcomas and 89% for chordomas, respectively. No severe side effects > CTC degrees III have been observed. CONCLUSIONS These data demonstrate the clinical efficiency and safety of scanning beam delivery of carbon ion beams in patients with skull base chordomas and chondrosarcomas. The observation of tumor regressions at a dose level of 60 GyE may indicate that the biological effectiveness of carbon ions in chordomas and chondrosarcomas is higher than initially estimated.

Abstract
The interest and difficulty of sphenoid tumor imaging relate mainly to its great diversity. Detection may be difficult due to variable tumor size and often misleading clinical data. Because the sphenoid is located at the center of the skull base, tumor extension may be quite variable and difficult to assess, requiring sufficient knowledge of anatomy and imaging features to detect tumor spread, especially retrograde perineural spread, since this has a negative impact on prognosis.

Abstract
Paralysis of the caudal cranial nerves, e. g. the nervus glossopharyngeus, vagus and accessorius, may cause disorders in swallowing and speaking leading to a reduction in the patient's quality of life. Glomus tumors or malignant lesions of the skull base are a frequent cause of such lesions. We report on the case of a 48 year old patient who presented an acute lesion of these cranial nerves in combination with paresis of the nervus hypoglossus as a result of an aneurysm of the internal carotid artery directly underneath the base of the skull. The aneurysm was treated by parent vessel occlusion. The results of this procedure were a shrinkage of the aneurysm and an improvement in the neurological symptoms.

Abstract
Sphenoid sinus mucoceles are pseudocystic expansile slow-growing processes that arise within the sphenoid sinus. A dynamic process of bone resorption and erosion results in a pseudo-tumoral development. Clinical features and potential risks are related to mass effect with compression of the optic nerves and intracranial extension of the process. CT and MRI allow diagnosis and distinguish mucoceles from skull base tumors or inflammatory diseases. Endonasal endoscopic approach is adapted to the treatment of sphenoid mucoceles and allows marsupialization of the mucoceles.

Abstract
We report a rare case of a dura-based intracranial schwannoma in the temporal fossa. A 77-year-old man admitted to our hospital with a 5 months history of mild recent memory disturbance. Magnetic resonance imaging (MRI) revealed a slight enhanced solid mass with a cystic mass in the right temporal lobe. Preoperative diagnosis was glioma and then total resection was performed by the transsylvian approach. Dense adhesion of the tumor to dura matter of the middle cranial fossa was confirmed during surgery. Microscopic examination of the tumor showed biphasic pattern with cellular Antoni A and hypocellular Antoni B areas. Immunohistochemically, the tumor was positive for S-100, vimentin and Schwann/2E and was negative for GFAP. From these findings, the tumor was diagnosed as a schwannoma arising from the dura matter of the middle fossa. The patient was discharged from our hospital with no neurological deficits. Intracranial schwannomas, which are not associated with cranial nerves, are rare. Our case was classified according to the origin into dura-based intracranial schwannoma. To our knowledge, only 14 cases of dura-based intracranial schwannoma have been reported, mostly in children and young adults. This represents the oldest case in the literature of dura-based intracranial schwannoma.

Abstract
OBJECT The authors analyze the factors that predispose to persistent hydrocephalus in children with posterior fossa tumors and compare their results and treatment policy with those described in the literature, particularly with regard to the higher postoperative shunt insertion rates, which have led some authors to the routine use of preoperative third ventriculostomy. METHODS The clinical records of 180 children treated for posterior fossa tumors in the Department of Pediatric Neurosurgery of the National Institute of Neurosurgery, Budapest, Hungary, between 1990 and 2000 were retrospectively reviewed. CONCLUSIONS The low postoperative shunt insertion rate in our series (15.5%) led us to believe that the routine use of preoperative third ventriculostomy is not entirely justified. Factors such as patient's age and tumor type, which showed a statistically significant association with the postoperative shunt requirement in our study, should be considered when the decision regarding treatment is made.

Abstract
We present a patient with a biopsy-proved sinonasal intestinal-type adenocarcinoma who presented with moderate confusion. He was found to have bifrontal hemorrhages, which to our knowledge has not been previously described in the literature for this entity. Intestinal-type adenocarcinoma should be in the differential diagnosis of aggressive lesions in the base of the skull with intracranial spread from the paranasal sinuses.

Abstract
Garcin syndrome is characterized by a progressive ipsilateral involvement of cranial nerves, culminating in paralysis of all or at least seven of them, without sensory or motor long-tract disturbance, with no intracranial hypertension, and with osteoclastic involvement in the skull base on radiographic computed tomography. Giant cell tumor is a primary bone tumor rarely affecting the skull base. An 8-year-old female presented with a 3-month history of increasingly worsening right otalgia, tinnitus, hearing loss, right facial numbness, and diplopia. She was admitted with a 2-week history of swallowing difficulties, voice change, and right shoulder pain. Neurologic examination disclosed unilateral paralysis of the right fifth through twelfth cranial nerves, with no other abnormal neurologic findings. Skull radiographic computed tomography revealed lytic lesions in the right temporal petrous portion. Computed tomographic scan indicated a destructive mass involving the right greater wing of the sphenoid bone and temporal petrous apex. Magnetic resonance imaging demonstrated a tumor arising from the temporosphenoidal region, infiltrating neither the brain nor the brainstem. No hydrocephalus was observed. Biopsy revealed giant cell tumor. Posterior treatment consisted of radiotherapy. At an 8-year follow-up, the patient was well but with functional sequelae. There is no magnetic resonance imaging evidence of tumor growth. No other giant cell tumor presenting as Garcin syndrome is known to have been reported.
