Formation of the ventricular system begins at the time the neural groove closes to form a neural tube. Fluid is present within the tube, even before the choroid plexus anlage appears. This fluid serves as a structural support for the tube, as well as a pathway for diffusion of metabolites prior to the formation of blood vessels. In the small, thin-walled fetal brain, fluid movement is character...

Hydrocephalus communicating with the basilar subarachnoid cisterns may manifest itself as enlargement of these spaces. Confirmation of this finding is based on resolution of dilatation after ventricular shunting. A series of eight patients points out the CT characteristics, the differential diagnosis, and the importance of the cisternal ventricle in the transmission of CSF.

The flocculus may simulate a cerebellopontine angle mass in computed tomography (CT). The CT appearance of the flocculus was compared with acoustic neuroma. Normal internal auditory canals, symmetric cerebellopontine angle cisterns, modest contrast enhancement, and a location posterior to the porus acousticus distinguish the flocculus from an acoustic neuroma.

Abstract At a time when European cities depended on three sources of fresh water for their domestic and industrial needs—rivers, spring-fed aqueducts groundwater wells—early modern Venice added fourth possibility: dense network cisterns capturing, filtering storing rainwater. was not unique in relying rainwater cisterns; but nowhere Italy (indeed Europe) the approach so systematic widespread, c...

Ultrastructural techniques and electron probe microanalysis were used to determine whether or not the smooth endoplasmic reticulum (SER) within presynaptic nerve terminals is a Ca-sequestering site . The three-dimensional structure of the SER was determined from serial sections of synaptosomes. The SER consists of flattened cisterns that may branch and are frequently juxtaposed to mitochondria ...

The objective of this study is to produce suitability maps for potential rainwater harvesting techniques (RWHT) in the West Bank (WB), Palestine. These aim reduce water scarcity, which a major problem conservation resources area. Based on literature reviews and expert recommendations, seven RWHts were selected (runoff basin system, contour ridges, cisterns, eyebrow terrace, check dam, on-farm p...

abstract meningeal melanocytoma is a primary melanocytic neoplasm with certain mr and immunohistochemical characteristics worthy to note. in a 38-year-old man with a complaint of headache for a couple of years and recently added nausea, vomiting, diplopia, progressive visual blurring and hearing loss, magnetic resonance imaging (mri) was remarkable for t1 shortening of leptomeninges and certain...

BACKGROUND Head injury contributes significantly to mortality and morbidity in India. Evaluation of the available trauma care facilities may help improve outcome. AIM To evaluate the factors influencing the mortality of patients with head injury who had intensive care management and evolve strategies to improve outcome. SETTING AND DESIGN Retrospective study in a tertiary hospital where int...
