Abstract A case of hemangioma calcificans in the 4th ventricle is reported. Skull x-ray films demonstrated a dense calcification in the posterior fossa. Computed tomography disclosed a hyperdense mass in the 4th ventricle. The clinical picture was of increased intracranial pressure due to obstructive hydrocephalus. An hemangioma calcificans in the 4th ventricle was removed successfully.

Common Histological Type

Abstract One hundred patients with brain tumors were diagnosed and treated during the first 24 months of life. They represent 16% of 608 children with brain tumors treated from 1952 through 1984. The most common histological type of brain tumors during the first 24 months are benign astrocytoma, medulloblastoma, and choroid plexus papilloma. The tumor location is distributed relatively evenly among the cerebellum and the 4th ventricle, the cerebral hemisphere (including the lateral ventricle), and the suprasellar region and 3rd ventricle. The chief presenting signs and symptoms are a full fontanelle, macrocephaly, changes of behavior, and delayed developmental milestones. Localizing signs are infrequent. Ninety-two patients underwent craniotomy with a one-month surgical mortality rate of 12%. The surgical mortality rate was 5.6% among 36 recent patients diagnosed by computed tomography. The 5-year survival rate is 41% in the patients younger than 12 months and 74% in patients diagnosed during the 2nd year of life. This study indicates the validity of Collins' rule for medulloblastomas during the first 24 months of life, but not for benign or malignant astrocytomas.

Using immunofluorescence with a panel of antibodies that recognize antigens expressed by oligodendroglia, the myelin-producing cells of the CNS, at different stages of differentiation from precursor to mature cell, we have investigated the development of cells of this lineage in cryostat sections of rat cerebellum. Our results are consistent with the view that glial precursors, identified by their expression of the ganglioside GD3, arise in the subependymal layers of the 4th ventricle and migrate to their final position in the cerebellum via the superior medullary velum, and to some extent the peduncles. As the cells reach their final destination they make the transition to recognizable galactocerebroside (GC)-expressing oligodendroglia, via a GD3+/GC+ intermediate. The myelin-associated protein 2′,3′-cyclic nucleotide 3′-phosphohydrolase (CNP) appears at the same time as GC, whereas myelin basic protein (MBP) is expressed 2–3 days after GC and CNP, immediately prior to myelin formation. A very clear progression of oligodendroglial differentiation was observed from the SMV into the base of the cerebellum, up into the white matter (WM) tracts of the folia, and then away from this central white matter into the granule cell and Purkinje cell layers, and finally the molecular layer. The time delay between the expression of GC, CNP and MBP was the same for oligodendroglia in all of these layers, suggesting the presence of an intrinsic clock controlling the initial expression of these myelin components. The early appearance of CNP in oligodendroglia suggests a role for this protein in the early stages of myelinogenesis.

Foramen Of Luschka

A Dandy-Walker malformation is an anatomical triad characterized by a large posterior fossa, agenesis of the cerebellar vermis, and dilation of the 4th ventricle. Up to 90% of patients will have hydrocephalus secondary to obstruction of fourth ventricular outflow through the foramen of Luschka and Magendie. The differential diagnosis of Dandy-Walker malformation includes Blake’s pouch cyst, a cystic structure originating within the roof of the 4th ventricle that herniates into the cisterna magna, and posterior fossa arachnoid cysts, which typically displace both the cerebellum and 4th ventricle anteriorly and demonstrate a propensity to enlarge. Brain MRI is the best diagnostic imaging modality to evaluate posterior fossa anatomy and cystic structures. Not all posterior fossa cysts require treatment. Indications for surgical intervention include enlargement, symptomatic mass effect and/or hydrocephalus.

ABSTRACTCentral neurocytoma (CN) is a benign intraventricular neuronal tumor with a favorable prognosis. It accounts approximately 0.25–0.5% of intracranial tumors. In this report, we describe a very rare case of tetraventricular CN with imaging-pathologic correlation, and discuss their atypical features in a location together with treatment options. A 27-year-old man was admitted to the hospital with symptoms of progressive headaches of several months' duration. Magnetic resonance imaging of the brain revealed a well-circumscribed, lobulated intraventricular mass with numerous intratumoral cystlike areas. The mass was located in the enlarged lateral ventricles bilaterally extending to the third and the fourth ventricle. Surgical removal of the 4th ventricle component of the tumor was performed. Histomorphological and immunohistochemical findings of the tumor were consistent with CN. After pathological diagnosis, gamma knife surgery was performed. CN may present with atypical features in a location with a usual histopathological findings. To our knowledge, we described the third case of tetraventricular CN, which was partially treated with both surgical resection and radiosurgery.
