of an excessive accumulation of cerebrospinal fluid (CSF) within the cranial cavity with subsequent dilation of the ventricular system. Hydrocephalus has been characterized by the anatomic relationship of the underlying disease process and abnormal pressure differences. Internal and external hydrocephalus refer to increased fluid accumulation within the ventricular and subarachnoid spaces, resp...

Hydrocephalus is uncommon in horses. However, in recent years, it has become clear that the prevalence of hydrocephalus is greater in Friesian horses than in other breeds probably due to their limited gene pool. Before identification of candidate genes that predispose to the development of hydrocephalus in Friesian horses can be pursued, an in-depth, phenotypic, pathological description of the ...

Background and Importance: This interesting case is about the presence of normal pressure hydrocephalus and a large pseudomeningocele at the same time after 13 months of posterior fossa surgery. Although the occurrence of a pseudomeningocele following posterior fossa surgery is not so rare, such a late large pseudomeningocele development with signs and symptoms of NPH after 13 months of surgery...

Background Meningitis is a common neurological emergency and a leading cause of death and neurological disability worldwide. MRI is extremely useful for detecting and monitoring the complications of meningitis. The purpose of this study was to describe the brain MRI findings in children with complicated meningitis. Materials and Methods  This cross-sectional study was conducted in Radiology De...

Objective Postoperative hydrocephalus is a common complication following craniectomy in patients with traumatic brain injury, and affects patients' long-term outcomes. This study aimed to verify the risk factors associated with the development of hydrocephalus after craniectomy in patients with acute traumatic subdural hemorrhage (tSDH). Methods Patients with acute traumatic SDH who had recei...

Increased intracranial pressure and ventriculomegaly in children with hydrocephalus are known to have adverse effects on white matter structure. This study seeks to investigate the impact of hydrocephalus on topological features of brain networks in children. The goal was to investigate structural network connectivity, at both global and regional levels, in the brains in children with hydroceph...

We developed a transgenic mouse line that expresses the Gi-coupled RASSL (receptor activated solely by synthetic ligand) Ro1 in astrocytes to study astrocyte–neuronal communication. Surprisingly, we found that all transgenics expressing Ro1 developed hydrocephalus. We analyzed these mice in an effort to develop a new model of hydrocephalus that will further our understanding of the pathophysiol...

In a population-based retrospective cohort of 5,353,022 California births from 1991 to 2000, 3,152 newborns were diagnosed with congenital hydrocephalus during the birth hospitalization. We compared demographic and clinical characteristics of infants with and without congenital hydrocephalus, and examined in-hospital fatality rates. The prevalence of congenital hydrocephalus was 5.9 per 10,000....

Hydrocephalus complicated the clinical course of four patients with pituitary adenoma. In three it was noted late, long after surgical intervention and radiotherapy had been carried out. In one patient, hydrocephalus was part of the presenting syndrome. The differential diagnosis of hypopituitarism and occult hydrocephalus is difficult. The possibility of hydrocephalus complicating a pituitary ...
