We report a case of a 12-year-old boy with previously shunted congenital hydrocephalus, presenting with a progressive headache, nausea, vomiting, and lethargy. In the brain magnetic resonance imaging, a large cyst was seen in the superior recess of the fourth ventricle extending through the cerebral aqueduct toward the third ventricle. Endoscopic dual fenestration of the cyst was performed successfully using the posterior suboccipital approach through the foramen of Magendie, which resulted in the relief of symptoms without any complications, and the patient was symptom-free in the subsequent follow-up visits for 4 years...

Meningiomas are benign tumors origin from central nervous system. They usually involve cephalic, paravertebral soft tissues, skin and in rare cases in the ear, temporal bone, mandible, foot, lung, and mediastinum. In this case, we report an unusual case of meningioma which placed in the fourth ventricle. A 14-year-old man with seizure and headache referred to our ward. The magnetic resonance imaging reported bilateral acoustic neuroma and fourth ventricle meningioma. The patient was scheduled for total tumor resection and the histopathology revealed psammomatous type of meningioma...

Schwannoma originates from the myelin sheath of peripheral nerves. It accounts for about 8% of all intracranial tumors. Commonly, schwannoma is located in the extra-axial locations; intra-axial schwannomas are extremely uncommon. The schwannoma arising from fourth ventricle is extremely uncommon and authors in a detailed PubMed and MEDLINE search could find only seven cases reported in the literature in the form of isolated cases report, who were managed surgically, with only one being a pediatric case. Authors report second case of intra-fourth ventricular schwannoma occurring in the pediatric age group...

For brain magnetic resonance (MR) examination, three-dimensional imaging is commonly performed. Radiologists need to know the appropriate imaging angle for viewing. We present six imaging angles for the axial images. Each angle is determined by the reference line. The landmarks on the midsagittal MR image to determine the angle of the reference lines are as follows: the supraorbito-meatal line (the center of the mammillary body and the fastigium of the fourth ventricle), the orbito-meatal (OM) line (the center of the mammillary body and the most posterior point of the cerebellar tentorium), the Talairach anterior commissure (AC)-posterior commissure (PC) line (the superior edge of the AC and the inferior edge of the PC), the Schaltenbrand AC-PC line (the center of the AC and the center of the PC), the subcallosal line (the inferior border of the genu and the inferior border of the splenium of the corpus callosum), Reid's baseline (the center of the pituitary gland and the most posterior point of the cerebellar tentorium) and the brainstem vertical line (the line perpendicular to the posterior border of the brainstem)...

We report a 10 days old newborn with brachycephaly, midfacial hypoplasia, syndactyly and broad distal phalanx of thumb and big toe. At the 20th gestational weeks an enlargement of the left cerebral ventricle and malformation of the fingers of the hands and toes were noticed on a regular ultrasound examination. The aforementioned malformations were observed at birth and at the age of 11 months. The large fontal was closed; the small one was palpable at the tip of the finger. Brachycephaly was evident with high full forehead, flat occiput, and irregular craniosynostosis especially at the coronal suture...

OBJECTIVES: The glymphatic system is a recently hypothesized waste clearance system of the brain in which perivascular space constitutes a pathway similar to the lymphatic system in other body regions. Sleep and anesthesia are reported to influence the activity of the glymphatic system. Because rats are nocturnal animals, the glymphatic system is expected to be more active during the day. We attempted to elucidate the influence of the glymphatic system for intravenously injected gadodiamide in the rat brain by 2 experiments...

BACKGROUND AND PURPOSE: The fastigium cerebelli is an important topographical landmark for neurosurgeons and radiologists. However, few studies have characterized the morphology of the fastigium cerebelli. We aimed to investigate the fastigium cerebelli using postmortem specimens and magnetic resonance imaging (MRI) in vivo. MATERIALS AND METHODS: Three cadaveric brains were midsagittally sectioned for observing the fastigium cerebelli. Additionally, 66 outpatients underwent MRI, including sagittal T1-weighted imaging, axial T2-weighted imaging, and coronal constructive interference in steady-state (CISS) sequence...

Medulloblastoma is a malignant brain tumor that is typically seen in children. It is classified as an embryonal tumor, classically located within the posterior fossa. When it involves the fourth ventricle, the patient commonly presents with signs and symptoms of raised intracranial pressure secondary to obstructive hydrocephalus. It is exceedingly rare for Medulloblastoma to occur in middle and late adulthood. In this paper, we present a case of a 51-year-old man who presented with a posterior fossa mass that was diagnosed later as Medulloblastoma...

RATIONALE: Mild-to-moderate alcoholic cirrhosis of the liver is related to spontaneous intracerebral hemorrhage (ICH). In terms of spontaneous brainstem hemorrhage, pontine is considered as the most common site in contrast to medulla oblongata where the hemorrhage is rarely seen. This rare primary medullary hemorrhage has been attributed so far to vascular malformation (VM), anticoagulants, hypertension, hemorrhagic transformation, and other undetermined factors. PATIENT CONCERNS: Herein, we describe a 53-year-old patient with 35-year history of alcohol abuse was admitted for acute-onset isolated hemianesthesia on the right side...

OBJECTIVES: The schwannoma of the trochlear nerve is rare and originates mostly from the distal parts in interpeduncular cistern. Lesion of the proximal segment in the inferior pineal region is extremely rare. Because of the rarity of the disease, the surgical approach to this region for the resection of trochlear nerve schwannoma has not been well documented in the literature. We herein describe an innovative and novel approach for the successful resection of the trochlear nerve schwannoma...

Background: Increased brain volume (BV) and subsequent herniation are strongly associated with death in pediatric cerebral malaria (PCM), a leading killer of children in developing countries. Accurate noninvasive measures of BV are needed for optimal clinical trial design. Our objectives were to examine the performance of six different magnetic resonance imaging (MRI) BV quantification measures for predicting mortality in PCM and to review the advantages and disadvantages of each method...

Growth hormone (GH) and the insulin-like growth factor I (IGF-I) have cell proliferative and differentiation properties. Whether these hormones have a role in mutagenesis is unknown. Nevertheless, severe IGF-I deficiency seems to confer protection against the development of neoplasms. Here, we report five cases of adult patients with severe and congenital isolated GH deficiency (IGHD) due to the c.57+1G>A mutation in the GHRH receptor gene, who developed tumors. Four GH-naïve subjects presented skin tumors: a 42-year-old man with a fibroepithelial polyp, a 53-year-old woman and two men (59 and 56 years old) with epidermoid skin cancers...

Dandy-Walker malformation is a rare disease of the central nervous system pathology (congenital malformations of the fossa cranii posterior). The key features of this syndrome are an enlargement of the fourth ventricle; complete absence of the cerebellar vermis, the posterior midline area of cerebellar cortex responsible for coordination of the axial musculature; and cyst formation near the internal base of the skull. Pregnant patients with Dandy-Walker malformation are at high risk and are managed by multidisciplinary teams including neurologists and obstetricians...

INTRODUCTION: Focal hydrocephalus including trapped temporal horn (TTH), isolated lateral and fourth ventricles, is caused by obstruction and/or adhesion related to various etiologies. With the advent of the neuroendoscope, endoscopic procedures have become an alternative in selected cases. CASE REPORT: A 2-year-old male from a rural town in México was referred to our institution because of multiple supra- and infra-tentorial abscesses and hydrocephalus. The patient had progressive deterioration and developed bilateral trapped temporal horn related to multi-septated hydrocephalus, so we performed an endoscopic ventricular-cistern-ventriculostomy through a single right temporal burr hole...

Choroid plexus papilloma is a rare intracranial neoplasm. These lesions most commonly present in the fourth ventricle in adults and lateral ventricle in children. Herein, we report a case of a 57-year-old male with complaint of backache of few weeks duration. Magnetic resonance imaging revealed an intradural and extramedullary space occupying lesion at D8 level. Histology showed multiple free-floating papillae with a central fibrovascular core. The cells showed immunoreactivity for vimentin, glial fibrillary acidic protein, synaptophysin, S-100 protein, and cytokeratins (CK, CK7)...

Arachnoid cysts (ACs) within the fourth ventricle are rare, and only a few cases have been reported in the literature. These are benign lesions within the arachnoid membrane, and they have been reported to occur in almost all locations where arachnoid is present. Different procedures have been performed to restore a normal cerebrospinal fluid dynamic and/or pressure, including shunting and partial or complete excision of the cyst by open microsurgery or endoscopic fenestration. We report the case of a fourth ventricle AC successfully treated using only endoscopic anterior trans-frontal cyst fenestration/marsupialization and standard third ventriculostomy...

Craniopharyngiomas usually involve the sella and suprasellar space. Their occurrence in the posterior fossa without extension to the suprasellar region is uncommon with only 16 cases reported in the literature. We report a case of a primary posterior fossa craniopharyngioma that was managed by complete excision with a good recovery. Our case was unique in that the craniopharyngioma occurred in the fourth ventricle and extended downward to the level of C1, a manifestation that was reported only twice in the past...
