My daughter was diagnosed with Stenosis of the Foramen Magnum and a syrinx extending from C1-Tll at age 6. What is expected long term?

My daughter was diagnosed with Stenosis of the Foramen Magnum and a syrinx extending from C1-Tll at age 6. What is expected long term?

Surgery @ some point: The syrinx may not be very symptomatic now but this with the narrowing of the bony entrance to the spinal cord will likely cause chronic headaches and other symptoms by the teen years. At some point they will want to go in and remove the bag like syrinx and create more room in the bony entrance to the cord. It is a major surgery but in gifted hands can solve the problem. ...Read more

What does it mean? My report says the report says there is mild cerebellar tonsillar ectopia with tonsils extending 5mm through the foramen magnum

Chiari Malformation: Well at least one of the features is present. Low lying cerebellar tonsils are dipping into the foramen magnum which is the big hole at the base of the skull that allows the spinal cord to pass up to the brain. It means no more trampolines, bungee cord jumping or roller coaster rides for you. You don't want the cerebellar tonsils to be forced down further. Look up arnold chiari malformation, . ...Read more

MRI:mild bilateral cerebellar tonsilar ectopia at the level of the foramen magnum borderline phenomenon. What does that mean. Pls explain thanks. ?

MRI:mild bilateral cerebellar tonsilar ectopia at the level of the foramen magnum borderline phenomenon. What does that mean. Pls explain thanks. ?

Usually not much: This usually means that a small part of the back portion of the brain (cerebellar tonsils) descends into the spinal canal very minimally. Usually this is incidental, and nothing needs to be done about it. However, not a bad idea to meet with your primary care doctor and discuss it and be examined in the context of this finding. ...Read more

FOR MY MOM INFERIOR CEREBELLAR TONSILLAR ECTOPIA 1.2CM BELOW FORAMEN MAGNUM.THERE IS A ASYMETRIC HERNIATION OF CEREBELLAR TONSILS RIGHT-1.2CM LEFT-8MM?

Chiari malformation : Arnold chiari malformation type 1 is defined by cerebellar tonsils that extend below the foramen magnum. The symptoms range from none to headaches, numbness, pain and weakness. The condition can become life threatening when cerebrospinal fluid is blocked. It is important to see a neurosurgeon with experience treating this disorder to discuss the therapeutic options. ...Read more

Had a MRI of the braincan you tell me what it mean by the cerebellar tonsils are seen to extend 2mm caudal to the foramen magnum, compatible with mild ?

Had a MRI of the braincan you tell me what it mean by the cerebellar tonsils are seen to extend 2mm caudal to the foramen magnum, compatible with mild ?

Location, location!: Cerebellar tonsils (not to be confused with lingual tonsils in the throat) are at the lower end of the cerebellum and are close to the rim of the opening at the base of skull (foramen magnum = big hole). If the f.M. Isn't big enough & tonsils protrude thru it, not enough space for brainstem may be present, causing compressive symptoms. Also CSF (spinal fluid) may not drain properly-->headaches etc. ...Read more

Slight crowding of the foramen magnum and tonsils are descended 2.5mm, have a thoracic syrinx but xray and ns say not chiari. What else could causeit?

Slight crowding of the foramen magnum and tonsils are descended 2.5mm, have a thoracic syrinx but xray and ns say not chiari. What else could causeit?

Could be congenital: Tonsils need to extend greater than 5mm to be considered a "chiari" malformation. Probably just congenital. We'd be happy to review your scan at metismd for a second opinion. ...Read more

What is a foramen ovale?

What is a foramen ovale?

Normal hole: A foramen ovale is a normal opening between the upper chambers of the heart. It is present in every normal fetus to allow blood with oxygen to get from the placenta to where it needs to go in the fetus's body. This opening usually closes after birth, but is present in about 20% of all adults. It has been associated with some forms of stroke, migraine headaches, and decompression illness. ...Read more

What is the foramen ovale?

What is the foramen ovale?

Porthole in atria: Everyone has a patent foramen ovale that is closed by a flap of tissue that keeps blood from flowing from one atria to the other. Sometimes it stays open a little longer than average and allows some blood to circulate right to left or vice versa depending upon other clinical conditions. The foramen usually closes w/o any intervention. ...Read more
