Objective : To investigate the efficacy of endoscopic third ventriculostomy (ETV) for infantile hydrocephalus. Methods : Retrospectively reviewed the 17 infantile hydrocephalus cases who were treated with ETV between July 2009 and June 2013. The study includes 17 patients (4 Han and 13 Hui) between the ages of 51 and 337 days. Five cases with encephalitis history and 2 cases with cerebral hemorrhage, with the remaining 10 cases congenital hydrocephalus. ETVs were performed for all patients with 1 case failing because the severe ventricle inflammatory adhesion, excessive exudation, and vague basilar artery. Results : Among the 16 successful cases 7 cases improved remarkably : heads and ventricles reduced and cerebral cortexes thickening morphologically. The ventricles of the remaining cases were unchanged. Conclusion : The ethnic minority account for the majority of the patients in this study. ETV is effective for infantile obstructive hydrocephalus.

Alexander disease is a rare degenerative leukodystrophy caused by dominant mutations in glial fibrillary acidic protein (GFAP). The neonatal form of Alexander disease may manifest as frequent and intractable seizures or obstructive hydrocephalus, with rapid progression leading to severe disability or death within two years. We report a case of a 50-day-old male who presented with intractable seizures and obstructive hydrocephalus. His initial magnetic resonance imaging (MRI) suggested a tumor-like lesion in the tectal area causing obstructive hydrocephalus. Despite endoscopic third ventriculostomy and multiple administrations of antiepileptic drugs, the patient experienced intractable seizures with rapid deterioration of his clinical status. After reviewing serial brain MRI scans, Alexander disease was suspected. Subsequently, we confirmed the de novo missense mutation in GFAP (c.1096T>C, Y366H). Although the onset was slightly delayed from the neonatal period (50 days old), we concluded that the overall clinical features were consistent with the neonatal form of Alexander disease. Furthermore, we also suspected that a Y366 residue might be closely linked to the neonatal form of Alexander disease based on a literature review.

We report a case of hydrocephalus in a 8-year-old boy who presented bilateral hand tremor. The hydrocephalus was caused by the aqueductal stenosis due to expanding lacunae in the mesencephalothalamic area on MR findings. The tremor was improved after CSF drainage by spinal tap and ventriculoperitoneal shunt. The authors present the possible mechanism of hydrocephalus induced tremor.

GBM is the most common primary brain tumor, but intraventricular GBM is rare and only few cases have been reported in the literature. The authors report a case of 64-year-old man who had a remote history of previous periventricular intracerebral hemorrhage. Brain computed tomography (CT) and magnetic resonance (MR) imaging showed an intraventricular lesion with inhomogeneous enhancement, infiltrative borders and necrotic cyst, and obstructive hydrocephalus. The patient underwent surgical removal through transcortical route via the bottom of previous hemorrhage site and the final pathologic diagnosis was GBM. We present a rare case of an intraventricular GBM with detailed clinical course, radiological findings, and pathological findings, and the possible origin of this lesion is discussed.

Fetal ventriculomegaly (VM) is a relatively common finding during prenatal examinations and occurs in approximately 0.2% of live births. Although there are various causes, obstructive VM due to cerebellar hemorrhage is exceedingly rare. A 33-year-old primigravida presented at 32 weeks of gestation with VM. At 36 weeks of age, a male infant was delivered via cesarean section. Postnatal imaging revealed severe bilateral hydrocephalus and space-occupying lesions in the cerebellum. Initial concerns about a potential germ cell tumor were raised due to elevated alpha-fetoprotein levels in both serum and cerebrospinal fluid. An external ventricular drain was placed to manage obstructive hydrocephalus. When the baby was 1 month old, surgical exploration revealed an old blood clot without any evidence of a tumor. Histopathological examination confirmed an old hemorrhage with no malignant cells. This case underscores the diagnostic challenges in distinguishing between hemorrhages and tumors in the context of fetal VM. Despite elevated alpha-fetoprotein levels, no tumors were identified. The underlying cause of cerebellar hemorrhage remains unclear despite extensive workups. Nevertheless, this case report details multifaceted diagnostic efforts to address the rare occurrence of cerebellar hemorrhage related to fetal VM, leading to a comprehensive case presentation.

We report a case of a patient with cystic subdural hygroma who underwent pre-operative Tc-99m DTPA cistrenoscintigraphy to determine the course of operation. A 68-year-old female was admitted to the department of neurosurgery because of acute subarachnoid hemorrhage. After emergency ventricular drainage, the hydrocephalus and cystic subdural hygroma in the right fronto-temporal area developed. She underwent Tc-99m DTPA cisternoscintigraphy to evaluate the type of hydrocephalus, which revealed obstructive communicating hydrocephalus and the communication between the subdural hygroma and the subarachnoid space. As a result of these findings, she underwent the ventriculo-peritoneal shunt operation without removal of the subdural hygroma. Post-operative brain CT showed nearly normalized shape and size of the right ventricle and disappearance of subdural hygroma. We recommend the pre-operative cisternoscintigraphy in patients with complex hygroma to evaluate the communication between subdural hygroma and the subarachnoid space.

Tectal glioma is an indolent and benign tumor that occurs predominantly in the pediatric population. It arises in the tectum of the midbrain and, due to its location, contributes to the development of obstructive hydrocephalus, typically presenting with increased intracranial pressure (IICP) symptoms or signs. Here we report a rare case of tectal glioma that presented as adult-onset epileptic seizures without IICP symptoms and was treated with endoscopic third ventriculostomy and antiepileptic drugs.

Objective : The purposes of this study are to investigate the factors that may be related to ventriculoperitoneal (VP) shunt in patients with cerebellar hematoma and the effect of severe fourth ventricular hemorrhage, causing obstructive hydrocephalus on subsequent VP shunt performance. Methods : This study included 31 patients with spontaneous cerebellar hematoma and concomitant fourth ventricular hemorrhage, who did not undergo a surgical evacuation of hematoma. We divided this population into two groups; the VP shunt group, and the non-VP shunt group. The demographic data, radiologic findings, and clinical factors were compared in each group. The location of the hematoma (whether occupying the cerebellar hemisphere or the vermis) and the degree of the fourth ventricular obstruction were graded respectively. The intraventricular hemorrhage (IVH) score was used to assess the IVH severity. Results : Ten out of 31 patients underwent VP shunt operations. The midline location of cerebellar hematoma, the grade of fourth ventricle obstruction, and IVH severity were significantly correlated with that of VP shunt operation (p=0.015, p=0.013, p=0.028). The significant variables into a logistic regression multivariate model resulted in statistical significance for the location of cerebellar hemorrhage [p=0.05; odds ratio (OR), 8.18; 95% confidence interval (CI), 1.00 to 67.0], the grade of fourth ventricle obstruction (p=0.044; OR, 19.26; 95% CI, 1.07 to 346.6). Conclusion : The location of the cerebellar hematoma on CT scans and the degree of fourth ventricle obstruction by IVH were useful signs for the selection of VP shunt operation in patients with spontaneous cerebellar hematoma and concomitant acute hydrocephalus.
