Abstract
BACKGROUND Rosette-forming glioneuronal tumor (RGNT) is a rare slow-growing neoplasm with mixed glial and neurocytic components. Surgical resection is the mainstay of treatment, whereas the role of adjuvant radiation therapies for residual or recurrent tumors has been poorly investigated. CASE PRESENTATION We describe the case of a patient with a recurrent fourth ventricular RGNT who was treated with two-staged Gamma Knife radiosurgery (GKRS). GKRS was effective in controlling tumor growth and safe up to seven years from treatment. CONCLUSIONS This case suggests that GKRS may be a safe and effective treatment for patients with recurrent or residual RGNT.

Abstract
Rosette forming glioneural tumors (RGNT) are a rare type of low-grade brain tumor included in 2007 in WHO classification. Given the benign nature of the disease, a complete surgical excision has been considered optimum. However, a handful of cases have reported the locally aggressive nature of RGNT. In addition, radiation may also be considered for a tumor located in areas where surgical excision is difficult. We present a similar case, where surgical risk was weighed against resection and we treated the patient with conformal radiation.

Abstract
We report a unique case of primary multiple liponeurocytoma. Liponeurocytoma is a rare benign tumor (Grade II) of the posterior cranial fossa with neural- or probably astrocytic-lineage cells; the tumor stroma contains mature adipocytes. This case is the thirty-eighth case of this pathology reported in the world literature and the first case of multiple form of this disease. We have provided a sufficiently thorough neuroradiological and histological picture that allows one to differentiate between a liponeurocytoma and other histological variants. Recommendations for the tactics for managing patients with this rare disease are proposed based on the analysis of treatment of this pathology reported in the world literature.

Abstract
Objectives:Central neurocytoma is a tumour that typically occurs in young adults in close association with the lateral and third ventricles of the cerebrum.Methods:We report the unusual case of a central neurocytoma that developed in the fourth ventricle of a 59-year-old woman and metastasized to the upper cervical canal. Subtotal excision and adjuvant radiotherapy were used to treat the lesion. Microscopic evaluation, discussion of the pathologic differential diagnosis and theories of the histogenesis of the tumour are presented. Results andConclusion:Fourth ventricular neurocytoma is rare and has only been reported twice previously. It appears most likely that this tumour arises from subependymal progenitor cell lines.

Abstract
Paclitaxel is an antineoplastic agent that is used in the treatment of a variety of solid tumors. Dose-limiting side effects of myelosuppression and peripheral neuropathy are well known. Paclitaxel has minimal penetration of the blood-brain barrier and central nervous system side effects are rare. However, transient encephalopathy following paclitaxel infusion has been described in adults but not in children. We present the case of a 14-year-old female with a recurrent suprasellar germinoma who developed an acute encephalopathy 4-6 hr following paclitaxel infusion.

Abstract
Invasive aspergillosis is an increasing problem in immuno-incompetent patients after prolonged steroid therapy, cancer radio-chemotherapy, and bone marrow or solid organ transplantation. Cerebral aspergillosis is a well-described complication of the invasive aspergillosis but only in rare cases, the brain is the sole site of infection. Despite increasing availability of antifungal drugs, the prognosis of cerebral aspergillosis is poor. We report on an 11-year-old boy with medulloblastoma in the area of the fourth ventricle. Following tumor surgery and radio-chemotherapy, several abscess-like structures occurred in the operating field. After incomplete abscess, resection histology and culture confirmed a localized Aspergillus fumigatus infection. The initial treatment of the Aspergillus fumigatus infection with conventional amphotericin B failed, and treatment with the triazole voriconazole was started. Intravenous treatment with voriconazole resulted in a reduction of the Aspergillus fumigatus abscess. After switching to oral ambulatory therapy, the Aspergillus fumigatus abscess increased in size. To improve treatment, voriconazole dosage was adapted to reach drug concentrations in cerebrospinal fluid (CSF) above the minimal fungicidal concentration and plasma specimens. During the concentration-controlled voriconazole therapy for a period of 18 months, a complete response was achieved.

Abstract
The authors report a case of a recurrent intracranial germinoma along the site of an endoscopic third ventriculostomy (ETV) after complete local tumor control using 3D conformal radiation therapy. A 13-year-old girl presented with sudden left upward gaze limitation for 4 days. A pineal region tumor and obstructive hydrocephalus were noted on magnetic resonance (MR) images. An ETV and tumor biopsy procedure were performed, which revealed the lesion to be a germinoma. The patient's visual symptoms and hydrocephalus disappeared postoperatively. Chemotherapy using cisplatin, etoposide, vincristine, and cyclophosphamide was initiated on postoperative Day 10. An MR image obtained 10 weeks after surgery and 2 weeks after chemotherapy revealed a significant (> 50%) reduction of the lesion. Radiation therapy was administered at 50.4 Gy to the target and 36 Gy to the periphery. Ten months after surgery, an MR image revealed further shrinkage of the tumor mass. One year after surgery, follow-up MR imaging demonstrated a small mass lesion at the entry site of the ETV, measuring 1.0 x 1.4 x 1.5 cm. An operation was performed to remove the small lesion, and pathological findings revealed it to be of the same histology as the primary tumor.

Abstract
OBJECTIVE To investigate the diagnostic method and analyze the result of microneurosurgical treatment for tumors of the fourth cerebral ventricle. METHODS Tumor of the fourth ventricle was clinically diagnosed in 86 patients basing on the preliminary assessment of symptom and CT or MRI findings. Of these 86 patients treated with micro-neurosurgery, the tumors in 62 were totally removed, subtotally in 19, and partially in 5. Forty-two patients received postoperative radiotherapy. RESULTS Three patients died postoperatively within ten days, and symptoms in 83 were improved after treatment. The average survival period was over 3 years. The pathology included 32 medulloblastomas, 23 ependymoma, 15 astrocytoma, 10 hemangiblastomas, 2 choroid plexus papillomas, and 4 epidermoid cysts. CONCLUSION Medulloblastoma, astrocytoma and hemangiblastoma are suggested to be removed totally whenever technically possible according to the site, character and volume of the tumor. For ependymoma, if close to the brain stem, is recommended to be subtotally removed. Postoperative radiotherapy may be beneficial for malignant types.

Abstract
We report the case of C.L., an 8-year-old child who, following the surgical removal of an ependymoma from the left cerebral ventricle at the age of 4 years, developed significant difficulties in retaining day-to-day events and information. A thorough neuropsychological analysis documented in C.L. a severe anterograde amnesic syndrome, characterised by normal short-term memory, but poor performance on episodic long-term memory tests. In particular, C.L. demonstrated virtually no ability to recollect new verbal information several minutes after the presentation. As for semantic memory, C.L. demonstrated general semantic competencies, which, depending on the test, ranged from the level of a 6-year-old girl to a level corresponding to her actual chronological age. Finding a patient who, despite being severely impaired in the ability to recollect new episodic memories, still demonstrates at least partially preserved abilities to acquire new semantic knowledge suggests that neural circuits implicated in the memorisation of autobiographical events and factual information do not overlap completely. This case is examined in the light of growing literature concerned with the dissociation between episodic and semantic memory in childhood amnesia.

Abstract
Neurocytomas gained importance since 1995, which is reflected by the increasing number of reports on this entity. This study was performed to determine the best available treatment for typical and atypical neurocytomas (MIB-1 labeling index >3%, atypical histology) in various age groups ( <or=18 years, >18 years). The data of all neurocytoma patients reported since 1982, when this entity were reviewed for age, gender, extent of resection, MIB-1 labeling index, histology, radiotherapy, and outcome of therapy. Patients were treated with complete resection alone (CTR), CTR plus radiotherapy (CTR + RT), incomplete resection alone (ITR), or ITR plus radiotherapy (ITR + RT). If the reported data were incomplete, the authors were contacted for additional data. Follow up had to be at least 12 months. Data were complete in 438 patients (73 children, 365 adults). Three hundred and fifty-one patients had typical, 87 atypical lesions. Typical lesions were associated with better local control and survival than atypical lesions (P < 0.001). CTR was superior to ITR (P < 0.001). After CTR, outcome was not significantly improved by RT. After ITR, RT improved survival in typical lesions (P = 0.03) and atypical lesions (P = 0.05), not in children (P = 0.16). Local control was improved in all groups (P < 0.001, children P = 0.01). Doses >54 Gy appeared beneficial after ITR of atypical lesions. In children, <or=50 Gy and >50 Gy were comparable.CTR does not require post-operative RT. Following ITR, RT improves outcome. Of 50-54 Gy appear sufficient for typical lesions, 50 Gy for children. Atypical lesions require 56-60 Gy.

Abstract
The authors describe a patient with auditory agnosia caused by a tectal germinoma. Despite having normal audiometric tests, the patient failed to recognize words and musical characters. On head MRI, the inferior colliculi were infiltrated by tumor. Neuropsychological tests revealed severe impairment in recognition of environmental sounds and words, defective musical perception, and stop consonant-vowel discrimination. Inferior colliculus may play a role in the analysis of sound properties.

Abstract
We report a case of a 15-year-old boy with desmoplastic medulloblastoma of the posterior fossa (T3M3, according to Chang classification) incompletely resected, with leptomeningeal and nodular spread in the posterior fossa and in the cervical and thoracic tracts of the spine, treated with sequential high dose iv chemotherapy and with hyperfractionated cranio-spinal radiotherapy. While on maintenance chemotherapy, the boy developed fever and septic status caused by Pseudomonas aeruginosa, and 1 week later also low back pain. Magnetic resonance imaging (MRI) demonstrated abnormal signal in the fourth ventricle and in the dorso-lumbar tract suggesting medulloblastoma recurrence, so he started with a chemotherapy program. Due to a worsening of back pain, a second MRI of the spine was performed that showed a spondilodiscitis of T11-T12 and L1-L2 discs. The histological and cultural examination of a fine-needle biopsy of the L1-L2 disc revealed the presence of P. aeruginosa. So patient was treated with intensive antibiotic therapy with resolution of the infection. Spondilodiscitis is a rare complication in neoplastic patients, maybe due to either immunodeficient status or invasive procedures such as lumbar puncture. This case demonstrates that MRI is a useful method for differentiating between infection and malignancy in the spine, but sometimes it may be difficult to distinguish metastatic tumor from a lesion due to spondilodiscitis. In this case surgicopathological assessment is crucial and mandatory.

Abstract
A 40-year-old male presented with hemangiopericytoma in the lateral ventricle manifesting as headaches persisting for 6 months associated with vomiting and visual obscurations for one month. Computed tomography and magnetic resonance imaging of the brain showed a large tumor in the trigone of the right lateral ventricle. The highly vascular tumor was completely excised. The histological diagnosis was hemangiopericytoma. Hemangiopericytoma is rarely located in the lateral ventricle and is difficult to differentiate from meningioma by neuroimaging methods.

Abstract
A 79-year-old female presented with difficulty ambulating and was found to have weakness and hyperreflexia in the lower extremities. Magnetic resonance imaging (MRI) revealed a large T8-T9 intraspinal tumor. She underwent a thoracic laminectomy, and excision of an intradural extramedullary lesion. The surgical specimen was soft, black tissue that consisted of a moderately cellular, deeply pigmented tumor. The neoplastic cells proved to be melanocytic, and were devoid of overt features of anaplasia, i.e., prominent nuclear pleomorphism, necrosis, significant mitotic activity, and high proliferation indices. Four months postoperatively, MRI demonstrated focal areas of enhancement in the conus medullaris and in the fourth ventricle, indicating leptomeningeal spread. Subsequently, the patient underwent whole brain radiation. On repeat imaging, there was nodular enhancement of the fourth ventricle and throughout the spinal cord. Despite chemotherapy and radiation therapy, the disease advanced and the patient expired. Meningeal melanocytoma is a rare, histologically benign tumor with good prognosis. However, local aggressive behavior has been recorded, especially in cases of subtotal gross resection. On a literature review, there was one case of cranial posterior fossa meningeal melanocytoma with associated lesions in both suprarenal glands and the left kidney, but there were no cases with distant metastasis. In this report, we present an unusual case of spinal meningeal melanocytoma with diffuse spread throughout the craniospinal axis that proved to be fatal.

Abstract
Central neurocytoma was first described by Hassoun et al. in 1982. The tumor is a rare benign tumor of the central nervous system, usually located in the lateral ventricles. Most reported cases are histologically and clinically benign. Several cases with recurrence have been described. Including the case presented here, only seven cases with craniospinal dissemination have been reported. None of the previous cases with dissemination had histological atypia but most did have a high MIB-1 labeling index (MIB-1 LI). Our patient had a high MIB-1 LI (4.6%) and dissemination was found to have advanced through the anterior horns of the lateral ventricles and to the spinal cord at the T4 level. The patient underwent partial resection of the tumor with follow-up radiation treatments for the residual tumor and dissemination. After the radiation, the size of the tumor decreased. The report of this casewill be helpful in the treatment of disseminated central neurocytoma.

Abstract
OBJECTIVE AND IMPORTANCE Diencephalic syndrome of emaciation (DS) is seen almost exclusively in infants and young children, and only two cases of DS in adults have been reported previously. We describe a case of DS associated with a third ventricle intrinsic craniopharyngioma in an adult patient. CLINICAL PRESENTATION A 54-year-old man presented with profound emaciation, disorientation, memory loss, and psychological disorders. Computed tomographic scanning and magnetic resonance imaging of his brain disclosed a tumor within the third ventricle. The preoperative endocrinological examination indicated an elevated growth hormone level and a decreased somatomedin C level. INTERVENTION The patient underwent partial resection of the tumor, which was adherent to the floor of the third ventricle but not to the ventricle wall, by an interhemispheric-transcallosal approach. The histological examination revealed a squamous papillary-type craniopharyngioma. The patient received 50 Gy of radiotherapy, which resulted in 90 to 95% reduction of the tumor size within 6 months, as indicated by the magnetic resonance images presented. The psychological disorders, memory disturbance, and severe emaciation improved gradually thereafter. CONCLUSION Although extremely rare, DS can occur in an adult harboring a tumor in the anterior hypothalamus.

Abstract
Primary central nervous system lymphomas (PCNSL) are infrequent tumors and their presentation as a solitary hypothalamic-third ventricle mass can be considered exceptional. We report the case of a 57-year-old woman with progressive visual deterioration, diabetes insipidus and mental confusion. She had a diffuse and homogeneous tumoral lesion involving the third ventricle and the adjacent hypothalamic area with marked enhancement after contrast administration on both, competed tomography scan and magnetic resonance images. It was approached and partially resected by the translamina terminalis route. Histological diagnosis proved to be a diffuse non-Hodgkin lymphoma and the patient subsequently was treated with adjuvant radiotherapy and chemotherapy. Followup examination showed visual acuity recover but persistent confessional state. Eight similar well described cases reported in the literature are reviewed with a description of the major diffenciating features of this neurological entity. Treatment of PCNSL remains a challenge, and the topographical location within the hypothalamic-third ventricle area is even more complex.

Abstract
Dissemination of malignant glioma to the fourth ventricle with metastatic deposits and intractable vomiting is rare. Leptomeningeal extension of malignant glioma is an uncommon condition that has been reported in patients with end-stage disease and is usually unresponsive to any treatment modality. We describe 3 patients with progressing recurrent glioblastoma multiforme in whom leptomeningeal invasion manifested itself as intractable vomiting due to tumor metastases in the floor of the fourth ventricle. All patients received additional radiation therapy focused to the posterior fossa, with complete resolution of vomiting occurring within 10 days after irradiation. The remission of symptoms in these patients persisted until their death 3-4 months after the repeat radiation therapy. These reports indicate that additional focused radiation should be considered because of its significant therapeutic effect in alleviating intractable nausea and vomiting in patients with glioma metastasized to the posterior fossa.

Abstract
Total excision is usually the recommended treatment for central neurocytomas. The role of radiation therapy in their management is controversial, and is usually reserved for partially resected or recurrent tumours. Long-term outcome was studied in patients with central neurocytoma who were treated with radiation therapy. By retrospective chart review, eight patients with intraventricular tumours, who had undergone radiation therapy following stereotactic biopsy, were identified. The diagnosis of neurocytoma was confirmed based on positive immunostaining with synaptophysin. Clinical and radiological follow-up was obtained. Of eight patients, one died 5 years after treatment from shunt dysfunction and 1 had disseminated intracranial disease 15 months after treatment. Six patients were symptom-free at a mean follow-up period of 78 months and had good local control as demonstrated by CT. Since this tumour can be confused with an oligodendroglioma or an ependymoma on routine histopathology (as happened in seven of our cases); immunohistochemical studies with synaptophysin should be routinely performed for intraventricular glial tumours. Our study supports the beneficial effect of radiation therapy in the management of these tumours.

Abstract
We report two patients with pure word deafness (PWD) with tumour in the III ventricle region with obstructive hydrocephalus. A diagnosis of PWD was made in these two patients in view of impaired verbal comprehension in the presence of adequate hearing, intact acoustic stapedius reflex and well preserved environmental sound perception. Return of verbal comprehension following the radiation therapy observed is probably due to the reduction of the tumour mass and the release of thalamocortical auditory pathways from its compressive effect. Our findings support the hypothesis of the presence of discrete auditory pathways for mediation of verbal and non-verbal stimuli independently.

Abstract
A 28-year old man with HCG-producing germinoma had undergone chemotherapy and radiotherapy. On admission for the fifth session of maintenance chemotherapy, he was found to be positive for hepatitis B (HB)s antigen, but negative for HBs antibody. HBs antigen had been negative during previous admissions. Since liver function was normal, the patient underwent chemotherapy. During myelosuppression after chemotherapy, liver dysfunction developed and acute HB was diagnosed. He fortunately showed seroconversion 2 months after onset. Serum immunological examinations are required for patients receiving chemotherapy.

Abstract
Deep-seated astrocytomas within the basal ganglia and the thalamus are considered unfavourable for microsurgical removal since the circumferential neighbourhood of critical structures limits radical resection. On closer assessment, the thalamus has a unique configuration within the basal ganglia. Its tetrahedric shape has 3 free surfaces and only the ventrolateral border is in contact with vital and critical functional structures, e.g. the subthalamic nuclei and the internal capsule. The purpose of the present study was to investigate the feasibility of maximum microsurgical removal in a series of intrinsic thalamic astrocytomas. 14 patients with intrathalamic astrocytomas grades I to 4 as diagnosed by previous stereotactic biopsy or intra-operative frozen section were selected for maximum microsurgical removal. The infratentorial supracerebellar approach from the contralateral side was used for 4 limited neoplasms of the pulvinar. For the other 10 larger and more extensive processes a parieto-occipital transventricular approach was chosen. Final histology gave the result of astrocytoma grade 1 or 2 in 4 patients, and of astrocytoma grade 3 or 4 in 10 patients. Postoperative MRI confirmed reduction of the tumor mass by 80 to 100% in 11 of 14 cases. Regional ancillary radiotherapy with 60 Gy was administered postoperatively for astrocytomas grades 3 and 4. Two patients operated on via the posterior transventricular approach had new postoperative partial hemianopia. Five of the 14 patients finally needed a ventriculo-peritoneal shunt. During the follow-up time of 6 to 52 months, tumor progression/recurrence was observed in 6 of the 10 high grade and none of the low grade neoplasms. The present pilot series demonstrates the feasibility of the microsurgical concept. Comparison with other treatment modalities, such as brachytherapy, requires future consideration.

Abstract
Central neurocytoma is a rare benign tumor of the central nervous system occuring in young adults and typically located in the ventricles. The tumor is composed of small round cells with neuronal differentiation and has a favourable prognosis. We report two cases of giant central neurocytomas with a triventricular extension in two young women. The first case concerned a 26 years old righthanded woman in whom an intraventricular mass was discovered, after a car accident with head trauma. Skull radiography showed an enlargment of the sella turcica. A CT scan performed in order to examine the pituitary gland revealed a voluminous and heterogenous intraventricular tumor with calcification. The second case concerned a 26 years old righthanded woman, presenting with a 4 Glasgow Coma Scale Score preceded by an acute onset of headache with projectile vomiting. A CT scan performed in emergency revealed a voluminous intraventricular mass with significant hydrocephalus. We review the different pathological and topographical patterns of previously published neurocytomas and discuss surgical management, effectiveness of radiation therapy and biological behavior.

Abstract
OBJECTIVE AND IMPORTANCE Intracranial germinomas often disseminate via the ventricular and subarachnoid pathways, but seeding to the perioptic arachnoid space is extremely unusual. We report two cases of recurrent germinoma seeding in the optic nerve. CLINICAL PRESENTATION Two men with pure germinoma were initially treated with three cycles of a three-drug regimen of bleomycin, etoposide, and cisplatin, and a complete response was achieved. Patient 1 experienced ventricle wall dissemination 10 months after undergoing the initial treatment and was successfully treated with three cycles of carboplatin and etoposide and then by 24-Gy whole-ventricle radiation. Twelve months later, he complained of progressive visual acuity loss, and magnetic resonance imaging demonstrated bilateral enhancement of the optic nerves. Patient 2 also experienced ventricle wall dissemination 3 months after undergoing the initial chemotherapy, but he exhibited a complete response after undergoing 24-Gy whole-ventricle radiation. Two years later, he complained of progressive visual acuity loss. Magnetic resonance imaging demonstrated bilateral enhancement of the optic nerves and cerebellar hemispheres. INTERVENTION None of the locations of recurrence were included in the irradiation field, whereas there was no recurrence within the radiation field. Complete responses were obtained with three cycles of a three-drug regimen of ifosfamide, cisplatin, and etoposide and then by 24-Gy whole-brain radiation that included the bilateral optic nerves. The visual acuity of each patient improved slightly. CONCLUSION Delayed seeding in the optic nerve may result from germinoma cells that remain dormant, so they cannot be destroyed by chemotherapy regimens alone.

Abstract
A third ventricle tumor, in addition to a recurrent cerebellar hemangioblastoma, was found in a 47-year-old woman on follow-up magnetic resonance imaging (MRI) 5 years after operation of the cerebellar tumor. On MRI, the tumor was hypo- to isointense on T1-weighted images and hyperintense on T2-weighted images compared with the normal gray matter, and was strongly enhanced with gadolinium. The tumor was first treated with fractionated conventional external-beam radiation (5120 cGy in 16 fractions over a 4-week period), resulting in a slight decrease in size of the tumor. For a definite diagnosis and mass reduction, surgery was performed using an interhemispheric translamina terminalis approach, resulting in a partial removal of the tumor due to profuse bleeding. Histological diagnosis was hemangioblastoma. Hemangioblastomas of the third ventricle are extremely rare and have not been specifically discussed. We describe the detailed clinicopathological features of the present case together with the possible explanation for the development of this tumor in this rare location.

Abstract
A 19-year-old male presented with a 4-week history of headache. Neurological examination showed bilateral papilledema. Computed tomography revealed a pineal region mass with remarkable obstructive hydrocephalus. Magnetic resonance imaging showed a pineal region tumor continuously invading through the tectum into the cerebral aqueduct and the fourth ventricle with the preservation of the adjacent structures. The tumor appeared an iso- to hypointense mass on T1-weighted images, a heterogeneous iso- to hyperintense mass on T2-weighted images, and a heterogeneously enhanced mass after administration of contrast medium. Histological examination after endoscopic biopsy confirmed that the tumor was a pineoblastoma. Radiotherapy was given to the whole brain and the spinal cord, and magnetic resonance imaging showed complete remission of the tumor. Pineoblastomas are highly malignant tumors with seeding potential through the neighboring ventricle or along the meninges, and this type of tumor becomes larger with local extension. We found no previous reports of the continuous extension into the fourth ventricle. The present case showed ventricular extension with minimal mass effect to adjacent structures, and did not disturb ventricular configuration. According to the unusual finding of ventricular extension, this rare case of pineoblastoma requires adjuvant chemotherapy.

Abstract
Regardless of the current progress in microneurosurgery, the operative management of tumors in the third ventricle is associated with a number of difficulties, and poses a serious challenge to surgeons. A numerous group of neoplasms with the aforementioned location are characterized by developmental course with secondary involvement of the III ventricle. Usually, it is a matter of tumors with suprasellar evolution (craniopharyngiomas, hypophyseal adenomas etc), penetrating through lamina terminalis and growing within the cavity of the ventricle. Radical removal of some of these tumors requires a many-staged approach--basal and transventricular--undertaken at different periods of time. The analysis covers five patients presenting tumors of the III ventricle--4 craniopharyngiomas and 1 dermoid cyst--where single stage basal (across lamina terminalis) and direct (transcallosal or across the lateral ventricle) access to the third ventricle is gained. The situations where such an approach is practicable, the peculiarities of the surgical technique, and the treatment results are discussed.

Abstract
A 26-year-old male with tuberous sclerosis developed a glioblastoma in the right temporal lobe 8 years after surgical excision and irradiation of a subependymal giant cell astrocytoma. The glioblastoma was probably an irradiation-induced tumor. Irradiation should not be given routinely for subependymal giant cell astrocytoma.

Abstract
A 50-year-old male presented with a central neurocytoma with intratumoral homorrhage. He had undergone partial removal of the tumor and postoperative radiation therapy 15 years previously. He was followed as an outpatient after the initial treatment, and there was no evidence of regrowth of the residual tumor. Removal of the hematoma and biopsy of the tumor were performed. Abnormally developed blood capillaries in the tumor may have undergone disturbances of circulation caused by irradiation which resulted in bleeding. Patients with partially resected central neurocytomas which have low proliferative potential may not require radiation therapy, due to the benign nature and the risk of delayed complications of irradiation including intratumoral hemorrhage.

Abstract
Intraventricular craniopharyngiomas are rare tumours. They are wholly within the third ventricle and can be distinguished from suprasellar lesions which extend into the third ventricle by the presence of an intact floor of the third ventricle. They are attached to the wall of the third ventricle to a variable extent, most commonly in the region of the tuber cinereum. The long-term follow-up on six cases treated by one of the authors is presented. Headache and visual disturbance were the most common presenting features but, unlike the more common suprasellar lesions, symptomatic endocrine disturbances were not a common presenting feature. Total surgical removal can cause hypothalamic damage and the resulting morbidity can be serious and sometimes life-threatening. Subtotal removal followed by radiotherapy is probably the treatment of choice for these lesions.

Abstract
BACKGROUND It has been suggested that the biologic behavior of central neurocytoma is indolent, although little is known regarding the role of radiation therapy and long term outcome. To clarify the role of radiation therapy and long term outcome, the authors retrospectively analyzed 15 cases of central neurocytoma. METHODS Clinical records and radiologic findings of 15 cases of central neurocytoma diagnosed at Seoul National University Hospital between January 1982 and February 1995 were carefully reviewed. The duration of follow-up was from 18-168 months (mean, 52 months); follow-up images were reviewed and the patient's Karnofsky performance scale (KPS) was assessed up to the time of last follow-up. RESULTS The age of the patients ranged from 15 to 60 years (mean, 25 years) and the male to female ratio was 11:4. Macroscopic total resection of the tumor was performed in seven patients, two of whom received fractionated radiation therapy. Subtotal removal of the tumor was performed in eight patients, five of whom received this same therapy. In 2 of the 5 patients who did not receive radiation therapy after macroscopic total resection, the tumors recurred 8 and 21 months after surgery, respectively; in contrast, recurrence was not detected in the 2 patients who received fractionated radiation therapy after macroscopic total resection. In all five patients who received fractionated radiation therapy after subtotal resection, the tumor shrank (n = 3) or disappeared (n = 2) during the postsurgical follow-up period ranging from 27-113 months; the tumor began to shrink from 6 months to 2 years after radiation. No change was found in the three patients who did not receive radiation therapy after subtotal resection. At the time of last follow-up, the KPS was greater than 90 in all patients except one who required assistance in his daily activities because of complications from radiation therapy. CONCLUSIONS It is suggested that even if the biologic behavior of a central neurocytoma is benign, radiation therapy appears to have an effect on tumor control. However, it should be carefully decided whether to use radiation therapy for a residual tumor because radiation can cause delayed complications and the clinical course of subtotally resected patients who do not receive radiation therapy is extremely benign.

Abstract
OBJECTIVE AND IMPORTANCE The prognosis for patients with ependymomas is related to the adequacy of surgical clearance. It is, however, often not possible to obtain a macroscopically complete resection of tumors arising in the posterior fossa. This may be because of the involvement of structures, the sacrifice of which would result in unacceptable morbidity, or because of metastatic lesions at diagnosis. For those patients in whom initial surgery was incomplete, elective second-look surgery may allow more complete clearance of tumor. INTERVENTION We have performed second-look surgery for fourth ventricle ependymomas in five patients: two women, aged 26 and 27 years, and three male patients, aged 4 months, 19 months, and 18 years. The 19-month-old male patient underwent early second-look surgery without receiving any interim chemotherapy. Second-look surgery on the other four patients was performed after they had received chemotherapy. No additional major morbidity was associated with the subsequent surgery, which achieved macroscopically complete clearances in four of the five patients. Three of four patients who underwent macroscopically complete resections were well, without clinical or radiological evidence of recurrent tumor, at 23, 25, and 34 months after their second operations. The 10-month-old patient who underwent early second-look complete resection relapsed locally at 33 months after surgery. Complete resection was not possible in one patient who had progressive tumor 8 months after second-look surgery. CONCLUSION For patients in whom complete excision of fourth ventricle ependymomas is not possible at initial surgery, second-look procedures may enable macroscopic clearance to be achieved with little morbidity. A larger study is needed to evaluate this approach to treatment.

Abstract
OBJECTIVE To present the feasibility and advantages of the biportal endoscopic management of posterior third ventricle tumors. As a result of recent developments in neuroendoscopy, classical third ventriculostomy has become a standard single burr hole procedure and a real alternative to shunting in the treatment of occlusive hydrocephalus. In patients with third ventricle tumors occluding the aqueduct, the acute development of hydrocephalus may often precede debilitating focal symptoms and signs. Forty percent of those tumors are radiosensitive, rendering craniotomy unnecessary. The goal of primary management is the alleviation of raised intracranial pressure and determination of the histological nature of the tumor. Cerebrospinal fluid shunting and the performance of a computed tomography- or magnetic resonance imaging-guided biopsy are generally suggested as the methods of choice. METHODS Three patients with posterior third ventricle tumors and acute hydrocephalus were treated in one session by computed tomography-guided endoscopic third ventriculostomy and endoscopic tumor biopsy was performed by means of two rigid ventriculoscopes. RESULTS Ventriculostomy was performed in three patients, and tumor biopsy was performed in two patients. The maximum 40-minute operation did not involve mortality or morbidity. Histological findings were established in all patients. In two patients with malignant infiltrative tumors, postoperative radiotherapy was used; in one patient with a small cavernoma, no further measures were taken. At the 6-month follow-up, flow-sensitive magnetic resonance imaging confirmed ventriculostomy patency in all patients. CONCLUSION The biportal endoscopic approach allowed independent visual control of both procedures, safe passages of the ventriculoscopes via the narrow foramen of Monro, and facile control of the intracranial pressure in the ventricles via the available four irrigation channels during the performance of tumor biopsy and fenestration of the floor of the third ventricle. In selected patients with infiltrating posterior third ventricle tumors, this procedure and postoperative radiotherapy may be an alternative to direct surgery or to shunting and performance of image-guided biopsy.

Abstract
The authors report 8 cases of central neurocytoma with a minimum follow-up of 3 years. Five patients were males and 3 females with average age of 21 years. All patients underwent surgical removal of tumor, and radiotherapy was delivered to 2 of the 3 patients in whom removal had been partial. At an average follow-up of 5 years, all patients are alive and none of them has presented signs of recurrence or progression of the disease. Some typical clinical and histological features of this tumor are pointed out.

Abstract
Over a period extending from 1984 to 1993, 16 children ranging in ages from 2 months to 12 years with posterior fossa ependymoma were treated. Four of these tumors were classified as lateral ependymomas because of their configuration and suspected site of origin. These 4 patients' ages ranged from 2 months to 5 years. Signs and symptoms of increased intracranial pressure and cranial nerve dysfunction were the hallmark of their presentation. Their imaging evaluation included a preoperative and postoperative CT san and/or MRI. A gross total surgical resection' was completed in the 4 children. At least a 1-year follow-up was available for all the patients. Intraoperative brain stem evoked potentials and facial and glossopharyngeal nerve monitoring were used in all the surgeries. Three children required a ventriculoperitoneal shunt postoperatively. Chemotherapy was used postoperatively in 3 children. The 4th child did not receive chemotherapy due to parental refusal and succumbed to a recurrence 1 years postoperatively. Radiation therapy was given to 2 children. Tumor recurrences developed in all children at 12 months, 18 months, 3 years and 4 years postoperatively in proximity to the original tumor site. Histologic sections in 3 patients, including those at the time of recurrence, were consistent with a low mitotic index. Only 1 child's histologic diagnosis was consistent with a high-grade ependymoma. The lower cranial nerve dysfunction transiently worsened in all the patients and was permanent in 2. The child's age, tumor histology and extent of resection play an important role in the prognosis of posterior fossa ependymoma. The lateral posterior fossa ependymoma has a particularly poor prognosis due to its location and its significant postoperative morbidity. The authors propose a combined midline and lateral suboccipital approach in order to expose the fourth ventricular floor, upper cervical spine, lateral recess, cerebellomedullary fissure, cerebellopontine and the cerebellomedullary cistern in an attempt at a "total' resection with a focus on the site of origin. The usage of neurophysiological monitoring appears to be useful in limiting and predicting the extent of postoperative complications. However, prolonged morbidity is likely and is commonly related to lower cranial nerve deficits. The author proposes a proactive approach in order to limit the sequelae of these complications.

Abstract
PURPOSE To see whether increasing the dose of hyperfractionated radiation therapy from 72 to 78 Gy would increase survival time in patients with gliomas, particularly those with brain stem or thalamic tumors. METHODS Seventy-eight patients with a clinical and radiographic diagnosis of a brain stem or thalamic glioma were enrolled in a trial to receive 78 Gy (1.0 Gy twice a day). Six patients with disease in other sites were also treated. The initial response to therapy was determined by comparing pretreatment magnetic resonance images and neurological examinations with those obtained within 2 weeks of completing therapy; subsequent responses were determined from bimonthly follow-up images. Time-to-tumor progression was measured from the date radiation therapy began until the date of documented radiographic or clinical progression. Survival time was measured from the date radiation therapy began until the date of death. Cox proportional hazards analysis was used to estimate the effects of specific variables on survival. RESULTS Of 81 evaluable patients, 68 received > or = 76 Gy, 10 received between 70 and 75 Gy, and 3 received between 60 and 68 Gy. The overall response or stabilization rate was 70.4%. Tumor size decreased in 30.8% of patients; 39.5% had stable disease, and 29.6% had immediate progression. The median survival time was 12.7 months (16.1 months for adults and 10.8 months for children). The median time to tumor progression was 9.0 months (11.4 months for adults and 8.4 months for children). A duration of symptoms < or = 2 months and a diffuse lesion were each associated with shorter survival and progression times. CONCLUSIONS For patients with brain stem or thalamic gliomas, increasing the dose of radiation therapy from 72 to 78 Gy did not significantly improve survival. Different treatment strategies are clearly needed.

Abstract
This paper describes a case of a patient (GX) with a brain tumour in the third ventricle who developed a syndrome of amnestic disorder and vegetative abnormalities (hyperphagia, oligodipsia) after irradiation treatment that followed brain surgery. The patient shows an extremely poor long-term memory on both visually and verbally presented material, and of autobiographical events occurring after the onset of the illness, but some preserved memory functions on short-term memory tasks, semantic memory tasks, and implicit memory tasks. Given the onset of symptoms only after irradiation (a memory deficit in particular), and the non-invasive nature of the surgery, the probable etiology is post-irradiation syndrome.

Abstract
During a period of 17 years (from 1976 till now) 45 patients with giant gliomas of the chiasma and the IIIrd ventricle out of a total amount of 120 patients with hypothalamic gliomas were operated. The following classification of tumours was used: I) tumours with predominant anterior growth; II) tumours which infiltrate chiasma and penetrate into the IIIrd ventricle; III) gliomas of the floor of the IIIrd ventricle and the chiasma, growing into the ventricle cavity; IV) tumours of the chiasma, optic tract and thalamus. The authors come to the conclusion, that surgical removal of giant tumours of the chiasma and the IIIrd ventricle, though risk, may result in an improvement or stabilisation of visual functions (77%) and a long period free from recurrencies (9.5%). The postoperative period is relatively favourable and the mortality is low (6%). The main contraindication in our opinion is a wide infiltration of adjacent brain structures by the tumour and spreading along both optical tracts. We consider the giant size of a tumour in itself a sufficient indication for surgery.

Abstract
Third ventricular ependymomas are rare tumors that have not been specifically examined. Four cases of these tumors are reported. The presenting symptoms included headache, ataxia, vertigo, and Parinaud's syndrome. All the patients underwent computed tomographic scanning and cerebral angiography, followed by craniotomy and microsurgical resection of the tumor. In addition, all patients had or developed symptomatic obstructive hydrocephalus requiring shunting procedures. Three of the patients are alive with a follow-up of 4 to 12 years. It is remarkable that these tumors are so rare, given that the ependymal surface area of the third ventricle is greater than that of the fourth. The management of these tumors should include aggressive surgical resection, radiation therapy, and cerebrospinal fluid diversion.

Abstract
Choroid plexus carcinoma is a rare neoplasm and occurs more frequently in children than in adults. Most of these neoplasms in adults arise in the fourth ventricle. A 22-year-old male with choroid plexus carcinoma presenting in the lateral ventricle is reported. The patient was treated by radiotherapy after surgical removal of the tumour. Modern management possibilities and its limitations are discussed.

Abstract
BACKGROUND Central neurocytoma is a rare intraventricular tumor with prominent neuronal differentiation. Although reported cases of this disease are increasing, the clinical benefit of radiation therapy remains unclear. METHODS From 1979 to 1990, two patients with central neurocytoma and five with well-differentiated neuroblastomas received radiation therapy. Five were men and two were women; the age at onset ranged from 20 to 37 years (mean age, 25.6 years). The follow-up period ranged from 14 to 134 months (median, 68 months). The initial histologic diagnosis was oligodendroglioma in five, ependymoma in one, and suspected central neurocytoma in one. Electron microscopic examination showed numerous neuronal processes containing microtubules and membrane-bound neurosecretory granules. Well-formed synaptic junctions were observed in the two cases of central neurocytoma. All patients underwent partial or subtotal tumor resection before radiation therapy (partial resection in three and subtotal resection in four). Three patients received radiation therapy locally, up to 50-60 Gy. Four cases were treated with a combination of whole brain irradiation (32-40 Gy) and local irradiation (20-32 Gy). RESULTS Treatment results were quite favorable, and all patients are alive and well without evidence of recurrence. Computed tomography studies showed that bulky residual tumors disappeared from several months to 1 year after the completion of radiation therapy. In a patient who had surgery again, significant vacuolar degeneration was observed by light microscopic examination. CONCLUSIONS A high level of radiosensitivity was confirmed, but additional data are required to clarify the clinical benefit of radiation therapy.

Abstract
Two young adult siblings independently developed similar neurological complaints that included headaches, photophobia, nausea, and intermittent lancinating facial pains. Magnetic resonance imaging revealed fourth ventricular lesions that required surgery in both patients. A pathological review revealed subependymomas with virtually identical histological features. The clinical features and common pathological findings of both patients suggest that familial subependymomas may have a maldevelopmental origin with genetic implications.
