What is dandy-walker syndrome (also known as dandy-walker malf)?

What is dandy-walker syndrome (also known as dandy-walker malf)?

Congenital defect: Drs dandy and walker described a brain defect in children that caused a cystic enlargement of the fourth ventricle due to lack of development of drainage holes that normally drain spinal fluid out of the fourth ventricle. This often causes large head, problems with balance, problems with learning, and seizures. Surgery relieves pressure but does not cure the defect. ...Read more

Dandy Walker Syndrome (Definition)

The Dandy-Walker Syndrome involves a rare congenital malformation that affects the cerebellum and fourth ventricle. Sign and symptoms may be apparent at birth or develop within the 1st year. They include: excess brain fluid (hydrocephalus),increased cranial size, delay of motor skills development, partial paralysis of limbs, and seizures. Also visual motor learning ...Read more

Can seizures harm a child with dandy walkers syndrome ?

Can seizures harm a child with dandy walkers syndrome
?

Yes: Seizures can be seen in people with dandy-walker malformation. Seizures are sudden changes in mental status, abnormal involuntary movements or behaviors that are due to abnormal electrical discharges in the brain. Usually, seizures are not harmful, but can be if prolonged (like >20 minutes) or they interfere with breathing and oxygen being delivered to the brain. ...Read more

Dandy walker variant prominent basal and convexity subarachnoid spaces third and lateral ventricles, what does this mean?

Brain anatomy: You (I assume it's you) have a congenital anomaly in the posterior cranial fossa where the hindmost part of the brain connects the spinal cord with the rest of the brain. Usually it's incidental i.e. causes no symptoms. In neurology 1 picture is worth 1000 words. Ask to see the MRI images & go over them with your neurologist. You have a right to an explanation in terms you understand. ...Read more

How does hypotonia relate to dandy walker syndrome?

How does hypotonia relate to dandy walker syndrome?

Cerebellar disorder: The dandy walker malformation is a defect of the outflow of fluid from the fourth ventricle of the brain. This can result in a large cyst, and can be associated with poor development of the cerebellum. Poor cerebellum function can result in poor muscle tone and poor balance that can be called hypotonia. This usually responds to therapy. Usually no surgery is necessary unless the cyst is severe. ...Read more

Are cerebral palsy, osteogenesis imperfecta or downs syndrome passed on to your children?

No,no,maybe: CP is an injury to the developing nervous system,it is not inherited. There are several forms of Osteogenisis imperfecta and their inherance varies.some do not survive infancy, some require an OI gene from both parents.Down syndrome males are usually sterile, females can reproduce and just under 50% of their babies would be DS. ...Read more

Are chiari 1 malformations ever acquired from a head injury or are they something people are born with? Is a 8mm chiari 1 malformation concerning?

Are chiari 1 malformations ever acquired from a head injury or are they something people are  born with? Is a 8mm chiari 1 malformation concerning?

Typically congenital: Many of these are congenital. It is essentially an area of your brain (cerebellum) that is partially herniated thru the large hole in your skull (foramen magnum). Some can be acquired (type 1) thru infection or trauma or things that result in elevated cranial pressure. Many congential type 1's are not symptomatic. If having c/o of headaches, weakness, or other symptoms i would see a neurosurg. ...Read more

Age 36 male, CT head revealed ich with biventricular extention with sah and cerebral oedema.Biventricular bleed persistent but resolvin hamatoma
help.

Cranial hemorrhage: The hemorrhage will usually resolve over 6-8 weeks. The need to watch for hydrocephalus or a build up of spinal fluid is indicated. Increasing headaches, confusion, nausea, vomiting, and double vision are common presenting symptoms. The early question to answer is why the hemorrhage occurred? Aneurysm, avm, infection, high blood pressure or trauma can cause the hemorrhage and needs to diagnosed. ...Read more

I have a posterior fossa arachnoid cyst last known 1.7x 1.6x3cm severe headaches, "pressure" in head epilepsy memory loss confusion&others ..related?

We usually think not: However, there are cases where arachnoid cysts cause symptoms such as headaches and other types of both cognitive, motor, & cognitive problems which get better when the cyst is removed. But that doesn't happen often. Usually, they're benign & have been there since birth. They don't need to be removed unless testing/examination suggests otherwise. If you'd like a 1-1 consult please let me know. ...Read more

How do arteriovenous malformations damage the brain and spinal cord?

How do arteriovenous malformations damage the brain and spinal cord?

Hemorrhage: Most of the damage of an arteriovenous malformation occurs when the blood vessel or vessels are spontaneously ruptured and bleed into the brain, causing pressure and damage to the brain. The same can occur with an av malformation in the brain stem or spine. ...Read more

Loud grinding sound in base of scull (neck) when turning head. Strong occipital headache. Have Ehlers Danlos. Is it chiari malformation? Other cause?

Loud grinding sound in base of scull (neck) when turning head.  Strong occipital headache. Have Ehlers Danlos. Is it chiari malformation? Other cause?

See your doctor : The grinding is generally a sign of digerati on in the facets, or neck joints. As an ED person, your ligaments which hold the bones in place are most likely lax, allowing excess movement. While,this could. Rear a chairing type malformation, I think arthritis is a more common answer. An X Ray will be telling ...Read more
