Hyperintensity in the Subarachnoid Space on FLAIR MRI

American Journal of Roentgenology, 2007
The purposes of this essay are to illustrate the causes of FLAIR hyperintensity in the subarachnoid space and to outline the mechanisms of the findings.FLAIR subarachnoid space hyperintensity may be encountered with both pathological conditions and artifacts. Knowledge of these conditions and appearances coupled with any associated findings may suggest

Microsurgical anatomy of spinal subarachnoid space

Surgical Neurology, 1983
The anatomy of the spinal subarachnoid space is reviewed with special reference to the work of Key and Retzius, the authors' own cadaver dissections, and experience from operative cases. It appears that despite some variations in the spinal arachnoid anatomy, there are many consistent features that can serve to guide the operating neurosurgeon.

Distribution of marked perilymph to the subarachnoidal space

Archives Of Oto-Rhino-Laryngology, 1980
In guinea pigs the tympanic perilymph of the basal turn was marked with fluorescing rhodamine. In the first series one drop of a 2% solution of the dye was applied onto the round window membrane. Since the perilymphatic space was not opened, the physiologic state of the communicating fluids perilymph and CSF was maintained.

Expansion of the Subarachnoid Space in the Lumbosacral Region

Radiology, 1968
A meningocele is defined in Dorland's Medical Dictionary as a hernial protrusion of the meninges through a defect in the skull or vertebral column (2). According to this definition, an expansion of the subarachnoid space within the spinal canal does not constitute a meningocele.

Benign enlargement of the subarachnoid spaces in the infant

Journal of Neurosurgery, 1981
✓ The authors report 18 infants with benign enlargement of the subarachnoid spaces seen at their institution during a 1-year time interval. This condition is characterized by the computerized tomography findings of dilatation of the subarachnoid spaces, normal or slightly enlarged ventricular size, and prominence of the basilar cisterns.

Ultrasound measurement of the subarachnoid space in infants

European Journal of Pediatrics, 1989
An original non-invasive method for easy and reproducible measurement of the subarachnoid space width in infants is described. Preliminary results of normal values during the neonatal period are presented as well as of the validity of the ultrasound method for abnormal values obtained by available computed tomography scanning.

Inflammation in the subarachnoid space.

2013
Abstract Classical pyogenic leptomeningitis is an acute, compartmentalized intracranial inflammatory response induced in the cerebrospinal fluid (CSF)-filled spaces of the subarachnoid space (SAS) and is characterized by the upregulated accumulation of a wide variety of host response factors and the production of 'pus'.

Meningothelial rosettes in the canine subarachnoid space

Acta Neuropathologica, 1985
A previously unrecognized type of rosette consisting of meningothelial cells is reported. Meningothelial clusters with a formation of numerous rosettes were incidentally observed in the canine subarachnoid space after single subarachnoid injection of 0.2 mg/kg of epinephrine.

Chronic catheterization of the spinal subarachnoid space

Physiology & Behavior, 1976
To administer drugs into the spinal subarachnoid space of unanesthetized and intact rats and rabbits, a procedure is described whereby a polyethylene catheter (PE-10) may be inserted through a puncture of the atlanto-occipital membrane and secured to the skull.

Scanning electron microscopy of the subarachnoid space in the dog. IV. Subarachnoid macrophages

Journal of Comparative Neurology, 1976
AbstractYoung dogs of both sexes were used in this study. Transmission and scanning electron microscopy were utilized for the examination of the spinal cord and choroid plexus with emphasis on the study of free cells. These procedures were modified so that, in certain cases, the same cells observed in scanning electron microscopy could be analysed ...
