hydrocephalus/edema

Three cases are presented in which a rare complication occurred after a shunt operation for hydrocephalus. On postoperative computerized tomography (CT) scans, extensive low-density areas appeared in the white matter along the ventricular catheter. After shunt revision, gradual resolution or

The case of a 63-year-old man with acute obstructive hydrocephalus is presented. To the authors' knowledge, this is the first reported case of acute obstructive hydrocephalus associated with nonketotic hyperosmolar diabetic coma. It is believed that the plasma hyperosmolality resulted in osmotic

We describe a single male infant who developed severe hydrops fetalis between 19 and 28 weeks of gestation. After delivery at 32 weeks he was treated by hemofiltration, prolonged ventilation and intravenous feeding. He had hypertelorism, orbital hypoplasia without proptosis, brachydactyly, frontal

CSF edema is observed in the periventricular white matter in acute hydrocephalus especially when the intraventricular pressure is elevated; there is usually no detectable disturbance of the blood-brain barrier. Histological and ventricular perfusion studies suggest that CSF flows through the intact

OBJECTIVE To evaluate the clinical significance of optic chiasmal edema (OCE) observed in hydrocephalus. METHODS Twenty patients with obstructive hydrocephalus and eight patients with communicating hydrocephalus were recruited. We classified both groups into OCE-positive and negative subgroups on

Our case demonstrates that nonimmune hydrops and hydrocephalus may be associated by the common pathway of intracranial hemorrhage and the development of anemia. The anemia apparently resulted in cardiomegaly with pericardial effusion and ascites as well as marked extramedullary hematopoiesis.

CONCLUSIONS Bioactive coils were developed to improve aneurysm packing and accelerate neointimal healing. Recent reports, however, have implicated these coils in the development of aseptic meningitis, perianeurysmal edema, and hydrocephalus. This report demonstrates that the same clinical phenomena

An important complication of cerebral malaria is increased intracranial pressure which, when severe, is associated with high mortality or neurologic sequelae. We describe a 7-month-old child with cerebral malaria for whom cerebellar edema and obstructive hydrocephalus were initial radiologic

Atrial natriuretic peptide (ANP) regulates fluid and electrolyte homeostasis in the central nervous system. In this study, we evaluated the effects of ANP on brain edema, intracranial pressure (ICP) and cerebral energy metabolism in congenital hydrocephalus in rats. Brain edema, indicated by the

OBJECTIVE Neurological deterioration, typically attributed to cerebral edema, is a rare but life-threatening complication in the treatment of diabetic ketoacidosis (DKA). We report the case of a child with DKA who became comatose but demonstrated acute obstructive hydrocephalus, instead of cerebral

T2 and diffusion weighted MRI, as well as 31P and 1H MRS were performed in kaolin-induced hydrocephalic rats. Extracellular white matter edema was detected in the early stages of progressive hydrocephalus. Phosphocreatine (PCr)/inorganic phosphate (Pi) ratios in hydrocephalic animals were decreased

Hydrocephalus induces interstitial brain edema, which causes neurological deficits, even if the intracranial pressure is maintained within the normal range, and the cerebral blood flow (CBF) does not decline to an ischemic level. The precise mechanisms underlying such edema-induced neuronal

The effect of a synthetic polypeptic hormone angiotensin-II on the structure of the brain ventricular system was studied in rats. A single injection of angiotensin-II, firm "Ciba", was given to rats in a dose of 0.05 mg/kg of body weight on the 1, 3, 7, 14 and 21st days. The brain was extirpated 15

A 59-year-old woman suffering from memory impairment visited our hospital. She was discharged nine years ago without complications after undergoing neck clipping surgery for intracranial aneurysm rupture and a right ventricular peritoneal shunt using the CODMAN^®

A 26-year-old man who had neurofibromatosis type-2 with symptoms of unexplained optic disc edema is reported. Magnetic resonance imaging (MRI) revealed bilateral acoustic schwannomas. Obstructive hydrocephalus, however, was not evident in spite of his severe disc edema and visual loss. After partial
