The aqueduct of Sylvius: a sonographic landmark for neural tube defects in the first trimester.
OBJECTIVES To describe a new first-trimester sonographic landmark, posterior displacement of the midbrain and aqueduct of Sylvius, which may be useful in early screening for neural tube defects. METHODS This was a prospective study of 457 normal fetuses at 11 + 0 to 13 + 6 weeks' gestation. We measured the distance from the posterior border of the aqueduct of Sylvius to the anterior border of...
متن کاملA historical lesson from Franciscus Sylvius and Jacobus Sylvius
OBJECTIVES One of the most commonly used eponymous terms in neuroscience and gross anatomy is Sylvius. The 2 most recognized uses of this term today are the sylvian fissure for the lateral cerebral sulcus and the sylvian aqueduct for the cerebral aqueduct. There is some controversy surrounding these terms because there were 2 famous anatomists named Sylvius after whom these structures could eas...
متن کاملSymptomatic subependymoma--a case report.
Subependymoma is a rare, slow-growing, benign noninvasive tumor of the central nervous system that may be located in the fourth ventricle, the septum pellucidum, the third and the lateral ventricles, the aqueduct, and the proximal spinal cord. Symptoms, if any, usually result either from direct compression of the brain stem or from acute hydrocephalus due to occlusion of the foramen of Monro or...
متن کاملThe value of early and comprehensive diagnoses in a human fetus with hydrocephalus and progressive obliteration of the aqueduct of Sylvius: Case Report.
BACKGROUND Mutant rodent models have highlighted the importance of the ventricular ependymal cells and the subcommissural organ (a brain gland secreting glycoproteins into the cerebrospinal fluid) in the development of fetal onset hydrocephalus. Evidence indicates that communicating and non-communicating hydrocephalus can be two sequential phases of a single pathological phenomenon triggered by...
متن کاملInternal Jugular Vein Cross-Sectional Area and Cerebrospinal Fluid Pulsatility in the Aqueduct of Sylvius: A Comparative Study between Healthy Subjects and Multiple Sclerosis Patients
OBJECTIVES Constricted cerebral venous outflow has been linked with increased cerebrospinal fluid (CSF) pulsatility in the aqueduct of Sylvius in multiple sclerosis (MS) patients and healthy individuals. This study investigates the relationship between CSF pulsatility and internal jugular vein (IJV) cross-sectional area (CSA) in these two groups, something previously unknown. METHODS 65 relap...
