Doctor insights on:
Does a 5.8 cerebellar tonsil herniation need surgery even if nothing else shows on mri. Used to be a herniation of 3.8 now its 5.8.?
Discuss with doctor: These symptoms can only be adequately diagnosed only after a thorough evaluation by your doctor. This may include labs and other satudies. Once all of the information is in, your doctor can let you know what's going on, and what to do to help you. ...Read more
What do my mri results mean; chronic microvas ischemic changes noted, frontal bone lesion & slightly abnormally shaped & low lying cerebellar tonsil.
Hard to say: urs best to discuss this with a neurology doctor, who can get full history. Picture by itself is just a picture-need medical hx and exam. So far it may look that there are changes- probably due to long history of smoking or other vascular disease .... As far as the shape of the brain parts and frontal lesion- it's impossible to tell without more info ...Read more
Not tonsils: The cerebellar tonsils are not tonsils, just part of your cerebellum. Sometimes when patients are dizzy it is due to pressure from a portion of the cerebellum resting low in the skull, around the foramen magnum. If a radiologist noted the cerebellar tonsils ride a little low, they might mention it in a report. It would not be that uncommon of a finding on a normal MRI or ct of the brain. ...Read more
See a neurosurgeon: This can be a signficant problem related to a brain or brainstem problem. If untreated, can cause serious harm. Seek medical attention from your doctor. ...Read more
Herniation.: The middle part of the cerebellum herniates through the foramen magnum (at the top of the spinal canal) in chiari ii malformation, causing a particular configuration of the cerebellar tonsils. ...Read more
Chiari malformation: A Chiari malformation is a situation where the cerebellar tonsils, two small structures at the base of the brain or forced through the hole at the base of the skull called the foramen magnum. The tonsils can developed a beak-like appearance or a "pencilling" due to the narrowed appearance on MR. ...Read more
Arnold Chiari: Low lying cerebellar tonsils refer to the presence of cerebellar tissue below the foramen magnum. Usually referred to as Arnold Chiari Type I, which are in general asymptomatic and seen as an incidental finding on MRI of the brain. Best to check with your doctor for certain. ...Read moreSee 1 more doctor answer
Borderline inferior cerebellar ectopia present, the cerebellar tonsils demonstrate mild
inferior herniation, measuring 4 mm sagittal sequence, means?
It most likely: doesn't mean anything. If that is the only finding, and the tonsils are otherwise normally shaped, some use less than 5mm as the normal range, so by that criteria 4mm would be normal. Others call 3-5mm benign tonsillar ectopia, an incidental asymptomatic finding. Most consider greater than 5mm to be abnormal(Chiari 1 malformation). The measurement is from the skull base to the tonsil tip. ...Read more
Incidental finding: The cerebellar tonsils project inferiorly from the cerebellum. If they extend below the foramen magnum (large skull base opening) lees than 5 mm, they are ectopic. If they extend more than 5 mm below, chiari i malformation must be considered clinically.Cerebellat. ...Read more
Mri stated "there are some what low lying cerebellar tonsils along the inferior margin of the foreman magnum, no tonsil ectopia." Should I be worried?
What does mildly low-lying cerebellar tonsils mean? What does unremarkable unenhanced brain parenchyma mean?
Had an MRI that stated I have low lying cerebellar tonsils. Could this be the cause of my daily neck pain or would it be something else?
If my cerebellar tonsils extend 4 to 5 mm below the foramem magnum and my CSF flow is normal, do I have Chiari or benign cerebellar ectopia?
Ectopia: Probably ectopia. Tonsils usually greater than 5mm below magnum for chiari. However would make sure your images were read by a neuroradiologist. Morphology/shape of the tonsils also important. Have seen borderline/mild cases missed . I suggest caution, there are other reasons why tonsils could be low such as CSF leak etc. ...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 ?
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
4th vent. tumor 2cm in size. My cerebellar tonsils descended 4mm. Would tumor account for descended tonsils? Is Chiari diagnosis immaterial due to tumor dx?
2 issues: Trust you are in contact with an experienced neurosurgeon. Surgery of Chiari issues is a very sub specialized area. The tumor is unlikely to be responsible for the "descended tonsils", but needs careful management. Problems such as yours may be associated with connective tissue disorders. Has that been considered? ...Read moreSee 1 more doctor answer
My MRIs yesterday showed cerebellar tonsils hanging down 5 mm. I had the MRIs because I've been having right facial numbness, usually upon standing after sitting for at least 30 minutes. My follow up with the neurologist is not until July 2nd. Im very ner
Does "somewhat low lying cerebellar tonsils" necessarily mean chiari? Mri states there is no evidence of tonsillitis ectopia.
Not Chiari: In Chiari malformation, a small part of the cerebellum protrudes through the bottom opening of the skull called the foramen magnum into the cervical spine where the spinal cord starts. This can cause neurological symptoms including headache. Based upon your description the radiologist thinks the position of the tonsils are not bad enough to call it a Chiari, also called "ectopic tonsils." ...Read moreSee 1 more doctor answer
