Is an external hydrocephalus consequence of brain atrophy ? Does external hydrocephalus make intracranial pressure ?

Is an  external hydrocephalus consequence of  brain atrophy ? Does   external hydrocephalus make intracranial pressure ?

Hydrocephalus: Hydrocephalus is a disorder where there is an increase in cerebral spinal fluid and subsequent dilatation of the internal spaces of the brain. It can be caused by obstruction of the circulation of the fluid or decreased absorption. Intracrania pressure is increased. However with brain atrophy due to loss of tissue these spaces appear dilated but the pressure is normal. There is no fluid increase. ...Read more

Hydrocephalus (Definition)

A condition in which there is an abnormal accumulation of cerebrospinal fluid or "brain fluid" within the brain which causes increased pressure inside the skull. It can ...Read more

Cure of brain dural av fistula?

Not enough info: I am sorry; that question is so general that it is impossible to give you a satisfactory answer in the 400 characters we're allotted. Are you the one with the a-v fistula? Has it bled? What does your neurosurgeon say? ...Read more

MRI of the brain 12.07.2014 CONCLUSION: external hydrocephalus. Lateral ventricles ASYMMETRICAL BRAIN L> R, Ext. Third ventricle is not expanded, the

Hydrocephalus: External hydrocephalus is a build up of cerebrospinal fluid over the surface of the brain rather than in the ventricles. Normally cerebrospinal fluid circulates from the brain to the spinal cord and back to the brain. When there is poor reabsorption or blockage then hydrocephalus (water on the brain) develops. See a neurosurgeon to help with treatment. ...Read more

Treatment for Hydrocephalus with posterior fossa cyst & VP Shunt insertion with pyogenic meaningitis?

Treatment for Hydrocephalus with posterior fossa cyst &  VP Shunt insertion with pyogenic meaningitis?

Pyogenic: infection in the face of a VP shunt will inevitably require that the shunt be removed, the infection treated with antibiotics and then the shunt replaced. ...Read more

Could T2 hyperintensity in the superior Semicircular Canal indicate Endolymphatic Hydrops or Menieres?

Could T2 hyperintensity in the superior Semicircular Canal indicate Endolymphatic Hydrops or Menieres?

Need to see pictures: T2 hyperintensity means fluid. But the semicircular canals have Endolymph fluid normally. Whether there is excess fluid (hydrops) that is causing symptoms (Meniere's) cannot be established with certainty by MRI. A dilated canal could indicate hydrops but that would depend on how the pictures look. Obtain a copy of MRI pictures & report to upload on HealthTap Prime; you'll get better answers there. ...Read more

How can ct/x-ray determine blockage of a vp shunt in intracranial hypertension (not hydrocephalus ) there is no change in ventricle sizing in iih?

They can't: A shunt blockage will not show on either ct or xrays. Useful methods to assess for blockage include 1. Radionucleotide shunt study 2. Shunt interrogation by your neurosurgeon, or 3. Dilated ophthalmological exam to check for papilledema. If in doubt circle back with your neurosurgeon. ...Read more

Av fistula, av graft, subclavian or femoral catheter, av shunt permanent or temporary, which is better?

AV fistula: Countless studies and decades of research have shown a clear advantage for patients who undergo hemodialysis through an av fistula. The second best is an av graft and all catheter-based modalities for hemodialysis are a distant third. ...Read more

How does derivation ventricle peritoneal used for hydrocephalus or intracranial hypertension work?

How does derivation ventricle peritoneal used for hydrocephalus or intracranial hypertension work?

Possibly vp shunt: I am not certain of the terms you are using. However hydrocephalus and intracranial hypertension can be treated with ventriculoperitoneal shunt where excess fluid inn brain is shunted through tubing to the abdomen where it is absorbed from the peritoneal surface. ...Read more

I have chronic severe ear infection w/csf leak since brain decompression for chiari malformation. Could inner ear & ear bones be malformed also?

I have chronic severe ear infection w/csf leak since brain decompression for chiari malformation. Could inner ear & ear bones be malformed also?

Unlikely: Unless your inner ear was involved in the surgery or you were born with inner ear or ear bone malformations, the inner ear and ear bones were likely unaffected from surgery. A suboccipital decompression typically does not affect the inner ear or ear bones. I would consult your otologist for a more precise answer. ...Read more

What's an external fixator?

What's an external fixator?

Fracture stabilizer : Some fractures are treated with external fixation instead of internal fixation. Plates and screws are used to hold the broken ends of the bone together while the fracture heals. These devices are placed under the skin and muscles. An external fixator uses pins in the bone to connect with bars outside the body. Both accomplish the same goal, to stabilize the fracture until it heals. ...Read more

Can obstructive aqueduct hydrocephalus after TB meningitis be cured with medicines? Lateral & third ventricles are dilated wid chronic locuna infarcts

Can obstructive aqueduct hydrocephalus after TB meningitis be cured with medicines? Lateral & third ventricles are dilated wid chronic locuna infarcts

TB meningitis: This devastating disease can produce brain infarctions by involvement of penetrating blood vessels and that is common in this illness. It also produces a basilar arachnoiditis which often results in obstructive hydrocephaly and this usually requires CSF shunting, commonly a ventriculoperitoneal shunt. See a neurosurgeon. Good luck. ...Read more

Could an MRI of the inner auditory canal show noise induced hearing loss?

Could an MRI of the inner auditory canal show noise induced hearing loss?

Not likely: Noise induced hearing loss involves more function than anatomy. Mri will show damaged tissue; eg drum, the bones of middle ear, etc. Audiometric testing will show degree of loss. An ENT and most family docs are able to differentiate between conduction loss vs sensory loss. ...Read more

Can people w/o hydrocephalus have CSF pressure increase or headaches caused by intracranial pressure?

Can people w/o hydrocephalus have CSF pressure increase or headaches caused by intracranial pressure?

Yes: The condition is called "pseudotumor cerebri" or "benign intracranial hypertension". It occurs most commonly in females between 20 and 40, especially in the overweight or obese. The definitive test is a spinal tap with direct measurement of the fluid pressure. ...Read more
