The differential diagnosis of retrocerebellar fluid collections in infants is important because of the prognostic implications. Usually the diagnoses are easy; however, shunting of the lateral ventricles or of the fluid collections may alter the appearance of the lesions, precluding accurate diagnosis. Under such circumstances a careful study of all the sequential radiologic studies is necessary.

We assessed ten prenatal magnetic resonance imaging(MRI) scans for fetal brain anomalies, and identified eight that were suitable for post-processing. Anatomical abnormalities were assessed on three-dimensional (3D) models and compared with two-dimensional (2D) imaging. We calculated the volumes of the intracranial ventricles and of a periventricular haemorrhage. In three cases, additional clin...

To determine the effects of diabetic ketoacidosis on the brain, we studied nine consecutive patients between the ages of 6 and 17 years by performing cranial CT on three occasions: on admission, before treatment; 6-8 hr after beginning treatment; and 7 days after admission. Both the pretreatment scans and those at 6-8 hr showed significantly reduced size of the lateral and third ventricles in c...

Neurocysticercosis, caused by Taenia solium, is a common cause of neurologic disease worldwide. Approximately 2,000 cases per year are diagnosed in the United States. Intraventricular neurocysticercosis is a severe form of the disease, in which cysticerci within the cerebral ventricles cause obstructive hydrocephalus. Symptoms of hydrocephalus include headache, nausea, vomiting, altered mental ...

Introduction: Arrested hydrocephalus is a state of chronic hydrocephalus with mild dilatation of the ventricles in which the cerebrospinal fluid pressure has returned to normal, and there is no pressure gradient between the cerebral ventricles and brain parenchyma. Case Report: In this case report, we present a 37-year-old female patient who was admitted to emergency department with complaints ...

Real-time ultrasound was used to make exact measurements from the lateral wall of the body of the lateral ventricle to the falx (the ventricular index) in 273 infants of varying gestational ages. The measurement performed in an axial plane through the temporoparietal bone correlated closely with an actual measurement made in coronal plane in 50 infants. A cross-sectional centile chart was drawn...

BACKGROUND Alzheimer's disease (AD) is one of the most common degenerative neurological disorders among elderly people, and is associated with progressive cerebral atrophy. AD is characterized by deterioration of the memory, difficulties with language, alterations in behavior and dysfunction in daily activities. OBJECTIVES The purpose of the present study was to measure the total volumes of d...

The possibility that displacement activities might be consequences of stress-induced humoral responses was investigated. Adrenocorticotropic hormone and glucose were injected into the brain ventricles of unrestrained domestic pigeons. ACTH leads to an increased frequency of yawning and headshaking and glucose to a decrease in arousal. It is concluded that these behavioural responses correspond ...

When infused into the lateral cerebral ventricles of rabbits, human endogenous pyrogen (EP) preparations induced dose-dependent increases in slow-wave sleep concomitant with increasing body temperature. Heating EP to 70 degrees C destroyed its sleep-promoting and pyrogenic activity. Anisomycin (an antipyretic) prevented EP from increasing body temperature without affecting its sleep-promoting a...
