A 3-year-old boy presented with headaches, vomiting, lethargy and papilledema. Communicating hydrocephalus along with transependymal fluid absorption and meningeal contrast enhancement was identified on CT. The enhancement was initially thought to be the result of a partially treated meningitis (child was previously on oral antibiotics for a presumed mycoplasma pneumonia). A right ventricular-peritoneal shunt was placed. CSF studies procured during the procedure were all normal. In contrast, CSF from a lumbar puncture contained a high protein, and cytology was highly suspicious for malignancy. Spine MRI showed diffuse leptomeningeal enhancement and a 1.5-cm intramedullary lesion at T12-L1 associated with minimal edema. The lesion was subtotally resected (70%) and diagnosed as an astrocytoma (mostly Kernohan grade 2 but with areas of grade 3). Chemotherapy was administered and follow-up spine MRI at 2 months did not reveal any residual tumor, however, the leptomeningeal enhancement persisted. Sixteen months later, at the completion of the chemotherapy and radiation therapy, the spine MRI remained unchanged. Neurological examination has always been normal. This case illustrates how a spinal cord astrocytoma can metastasize via spinocranial dispersion and present early with hydrocephalus rather than myelopathy.

Glioblastoma multiforme (GBMs) tumors are exceedingly rare tumors in the pineal region. We present three cases in which patients presented with a pineal/posterior third ventricular region mass and review all the previously reported cases in the literature. Pineal region GBM seems to be a very aggressive tumor with a high rate of leptomeningeal and ependymal metastatic disease. Patients usually present with signs and symptoms of hydrocephalus and Parinaud's syndrome. The clinical and radiological characteristics of pineal GBM do not differentiate it from other malignancies of this region, thus surgical biopsy is generally required for definitive diagnosis. Glioblastoma should be considered in the differential diagnosis of the pineal region tumors, especially when evidence of leptomeningeal or ependymal metastatic disease is present.

Diffuse intrinsic pontine glioma (DIPG) of childhood has a dismal prognosis. Clinical trials of new agents are vital and it is essential that the correct endpoints and disease assessments are chosen. A retrospective review of magnetic resonance imaging (MRI) scanning in a pure population of DIPG was undertaken. Baseline diagnostic MRI findings included; local tumour extension in upper medulla (74%) or midbrain (62%), metastatic disease (3%), basilar artery encasement (82%), necrosis (33%), intratumoural haemorrhage (26%), hydrocephalus (23%) and dorsal exophytic component (18%). Post-treatment MRI scans demonstrated increases in; leptomeningeal metastatic disease (16%), cystic change/necrosis (48%), enhancement (72%) and intratumoural haemorrhage (32%). Response rates were calculated according to both RECIST (4%) and WHO (24%) criteria. No MRI parameter in either the diagnostic or response scans had prognostic significance. We recommend that currently primary endpoints for DIPG clinical trials should be overall or possibly progression free survival and that new advanced functional imaging techniques should be explored as possible surrogate markers for novel therapy activity rather than conventional MRI response criteria.

Brain metastases (BM) are among the most devastating and debilitating complications of melanoma. This retrospective study was conducted to gain a better understanding of patient and disease characteristics that have the greatest impact on overall survival in melanoma patients with BM; therapeutic interventions were also assessed. The records of all patients diagnosed with cutaneous melanoma and BM who were seen at Memorial Sloan-Kettering Cancer Center between 1991 and 2001 were retrospectively reviewed. A variety of factors, including age at diagnosis of stage IV disease, gender, race, disease stage at diagnosis, presence of BM at diagnosis of stage IV disease, neurologic symptoms, radiographic findings, number of BM, status and site(s) of extracranial metastasis, and treatment modalities, were analyzed for correlation with overall survival using univariate and multivariate Cox regression models. The records of 355 patients with BM were included in the analysis. On univariate analysis, seven patient and disease characteristics were significantly associated with poorer survival: age > 65 years, extracranial metastases, BM at stage IV diagnosis, neurologic symptoms, four or more BM, hydrocephalus, and leptomeningeal metastases. Of these, age, extracranial metastasis, neurologic symptoms, and number of BM were significantly associated with poorer survival in a multivariate analysis. Multivariate analysis of treatment modalities suggested that patients who had surgery, radiosurgery, or chemotherapy with temozolomide had improved survival outcomes, although this analysis has limitations. The prognostic factors identified in this retrospective study should be considered when making treatment decisions for patients with BM and used as stratification factors in future clinical trials.

The authors report the case of a 16-year-old male who presented with a bifocal diencephalic tumor arising both in the neurohypophysis and the pineal region with hydrocephalus. The histological diagnosis obtained during endoscopic ventriculocisternostomy was germinoma. MRI revealed an increase of the neoplasm during chemotherapy with recurrent obstructive hydrocephalus. A new ventriculostomy was performed followed by total surgical resection. The final histopathological analysis demonstrated an immature teratoma. Subsequently, this patient developed metachronous cystic metastases in the cerebello-pontine angles, which were resected and identified as mature teratoma, then we observed a lesion of the brachium conjunctivum which stayed stable after 29 consecutive months. The patient is alive and feels well 6 years after the initial diagnosis and 5 years after the first metastasis. To our knowledge, this is the fifth case of the growing teratoma syndrome located in the brain but the first case with simultaneously bifocal location and infratentorial disseminated metastasis. Obviously surgical removal is the treatment of reference for teratomas. Metastases of teratoma can be mature and may be amenable to surgery with a favorable outcome. Primary intracranial germ-cell tumors (CGT) arise in the midline of the brain and are located in the diencephalon. The peak incidence occurs during the second decade of life. Germ cell tumor (CGT) includes germinomas and non-germinomatous tumors, mature and immature teratomas account for 19.6 % [1]. Curiously, teratomas are able to grow during the first weeks of chemotherapy while serum markers remain normal. This situation was originally described and designed as "the growing teratoma syndroma" (GTS) in primary testis tumors by Logothetis in 1982 [2]. Here we report the rare occurrence of a GTS in a teenager who presented metachronous cystic metastases located in posterior fossa which were histologically mature.

The common presentation of carcinoma stomach includes haematemesis, malaena and gastric outlet obstruction. Symptoms due to metastases to the liver and lung as part of the disease progression are usually preceded by the detection of a primary in the stomach. Carcinoma stomach, where the primary is silent, and which presents with truncal ataxia and features of hydrocephalus due to isolated metastatic deposit in the cerebellar vermis is exceptionally rare. The prognosis of such patients is poor and the treatment is palliative.

This 18-year-old woman presented with headache and diplopia over several months and was found to have an enhancing pineal tumor with resultant obstructive hydrocephalus. Following standard preoperative diagnostic tests, including spinal axis imaging, the patient was taken to the operating room for an endoscopic third ventriculostomy to relieve hydrocephalus and then subsequently underwent a craniotomy for gross-total resection of the pineal mass. The patient was discharged after an uneventful hospital course and received standard adjuvant cranial-spinal radiation and chemotherapy as an outpatient. Follow-up imaging 1 year after surgery demonstrated a metabolically active, lytic lesion in the C-3 vertebral body and new lung lesions suggesting a metastatic pineoblastoma. The patient underwent a C-3 anterior corpectomy and reconstruction without complication as aggressive therapy for presumed metastatic disease. Final pathological results from the vertebral lesion were consistent with radiation-induced reactive changes, not metastatic pineoblastoma as originally suspected. The patient recovered well and remains symptom free. To the authors' knowledge this is the first reported case of reactive changes mimicking metastasis in a single vertebral body following standard therapy for resected primary pineoblastoma.

A 64 year-old woman with a diagnosis of lung adenocarcinoma was admitted to our neurosurgical division in February, 2007, suffering from severe headache and dizziness. Systemic chemotherapy had been repeated for multiple metastases to the bone and cerebral cortex since 7 months before. Reexamination with MRI revealed mild hydrocephalus without cortical metastasis. Cytological analysis of the cerebrospinal fluid (CSF) provided the diagnosis of leptomeningeal metastasis. Removal of 8 ml of CSF dramatically alleviated the patient's symptoms. To improve the quality of her remaining life, she underwent lumboperitoneal (L-P) shunt using a Strata adjustable pressure valve. Severe headache disappeared and other symptoms gradually improved after the operation. She survived for 10 months after the shunt placement, perticipating in family life for 6 months. Pressure level of the Strata valve was changed twice according to the degree of hydrocephalus and functioned well while her life lasted. The present case showed that L-P shunt is one of the effective palliative procedures and an adjustable pressure valve is available for this kind of CSF shunt in patients with leptomeningeal metastasis.

PNETs of the spinal cord are aggressive and local recurrence and/or leptomeningeal spread is common. Primary spinal PNETs are extremely rare and most cases involving the spinal cord are drop metastases from primary intracranial tumors by cerebrospinal fluid. Herewith, we present a 40-day-old infant with multilevel primary spinal PNET at Th12-L1 and L5-S1 levels associated with hydrocephalus occurring nearly 15 days after the operation. According to our knowledge this is probably the first case harboring all these pathologies. Multilevel primary intraspinal PNET in an infant is even rarer and can be associated with hydrocephalus that occurs during the postoperative period.

We report the first case in the literature of a solitary metastatic melanoma of the septum pellucidum, mimicking a colloidal cyst of the third ventricle. In a 22-year-old man clinical and radiological examination revealed regional left inguinal, bilateral suprarenal and left broncho-pulmonary parailar nodular masses. Immunohistochemical staining on bronchoscopic, lymph nodes and neuroendoscopic biopsy confirmed the diagnosis of metastatic melanoma, in spite of extensive workup failed to detect a primary cutaneous or systemic tumor site. The clinical course was progressive and lethal. The neuroendoscopic approach to the septal lesion, performed before stereotactic radiosurgery, was extremely useful to obtain biopsy of the tumor and, by means of septum pellucidotomy, to treat biventricular hydrocephalus by monoventriculo-peritoneal drainage, in the same seat. Even if metastases can occur anywhere within the central nervous system, the novelty in this report is their intracranial localization, as they have been detected in the septum pellucidum, a case never reported previously.
