Mri scan of internal auditory canal
Common Questions and Answers about Mri scan of internal auditory canal
mri-scan
There is abnormal linear enhancement in the left internal auditory canal. The AICA does extend into the left internal auditory canal for some distance. Otic capsule structures appear unremarkable. No vascular abnormality is identified. Mastoid signal within normal limits. No other temporal bone signal abnormality is identified.
The other causes being Carotid stenosis (closing or narrowing of the vessel), vascular loop (of the internal auditory canal), Persistent stapedial artery (close to the stapes bone), etc.
I would encourage you to consult a good ENT surgeon and get it resolved. The chances of this above symptoms being Meniere’s disease are remote.
Anymore doubts you are welcome.
They suspect an intraosseous lipoma lesion at the anterior of clivus in the left IAC (Internal Auditory Canal?)... he will be getting an CAT scan for confirmation. He has been getting dizzy on and off for the last 6 months and finally went to get a check-up. EENT thought, it was a viral infection of the his inner ear. (Olive leaf extract had helped him get rid of the dizziness, how did this help his vertigo?)
What is the prognosis and treatment for this, if the findings are correct?
Type II anterior inferior cerebellar artery (AICA) c loop is present at the porus acousticus of skull and extends into around 50% of the internal auditory canal (IAC). When this is associated with the facial (VIIth cranial nerve) and vestibulocochlear (VII th cranial nerve) nerve, then it may cause compression of these nerves and result in hearing problems, facial pain or spasm, tinnitus etc. Your doctor will need to correlate your symptoms with this finding.
s - MRI brain and MRI internal auditory canal both with no contrast. The cost for (2) MRI exceeds my budget and I am going to only do one at this time. I am thinking the auditory canal would be best. What do you think?
The ENT has told me that I have no fluid, so would this change your suggestion of the possibility of having Meniere's or endolymphatic?
Thank you for getting back!
Dear Sir,
My father is 72 years old, one month before he had severe head ache and next day his speech was slurring then we go for neurology doctor. he asked to take MRI Scan the MRI Scan report is here.
Technique:
Multiplaner, multisequence MR imaging brain with contrast done. on 09.06.2009
Findings: T1 ISO intense, T2 slightly hyperintense, Flair ISO intense ( 2.3 x 1.7 x 2.
the tumor center, mostly located at the level of the internal acoustic canal, was spherical in shape with an acute angle between the lateral tumor border and petrous bone; and there was widening of the internal acoustic canal or destruction of petrous bone. However, the presence of an acoustic neuroma could not be excluded if widening of the internal acoustic canal was absent.
You need not worry much about the Technique of the MRI. T1, T2 and FLAIR are different ways an MRI scan is captured to detect different types of lesions.
The lesions in your brain suggest a vascular (blood circulation) problem. Since you are 33 now, you should get your blood pressure checked. Hypertension (high blood pressure) can lead to focal areas of cell death in the brain. The dizziness and the giddiness could also be due to the high blood pressure.
That would require the use of two different protocols - one for the narrow focus of the internal auditory meatus (meatus - canal) where a tumor on the accoustic nerve can grow and another for the brain under MS protocol.
When they look for the accoustic neuroma the MRI is not of the whole brain.
And CPA standing for Cerebello-Pontine Angle makes more sense than a blood test for platelet function. They are looking at the brainstem and related areas.
About the GAD.
No midline shift or hemorrhage and no unusual enhancing masses are seen within the internal auditory canals or within the brain. I have known about this cyst for 17 years from another MRI for the same symptoms. I am now experiencing lethargy, balance problems, lethary as well as being diagnosed with bi-polar disorder. I am waiting for Medi-Cal to find me a neuro-surgeon who will accept their ins. I would like to know from you if they can use laser surgery to remove this kind of cyst.
The auricular(ear) branch of the vagus nerve (nerve 10) innervates part of the external auditory (hearing) canal, the posterior wall of the external auditory canal, and the posterior portion of the tympanic membrane.
Ear pain can also be referred via cranial nerve 10 from the pharynx, larynx, trachea, diaphragm, thyroid gland, and esophagus, among other thoracic and abdominal structures

ve been diagnosed with a ossecus excresence representing an Osteoma/Exostosis arising in the roof of the internal auditory canal at the porus acousticus, causing significanat luminal compromise. My symtoms are occasional lightheadedness, roaring sound in my right ear and some facial numbness. Has anyone else experienced this....my doctor has me in a "watch and wait" status since the tumor/growth is approx 5 x 7 mm.
i want to know about the severity of my problem after a MRI scan . the scan was done as i was having severe pain accelerating to my buttocks . iam now on medicines and physiotherapy . The report says1) POSTERO-CENTRAL DISC PROTRUSION WITH CENTRAL L5-S1 LEVEL CAUSING CENTRAL CANAL NARROWING AND MLIDLY INDENTING THE TRAVERSING NERVE ROOTS
2)MILD PSEUDO DISC BULGE AT L4-L5 DUE TO ANTEROLISTHESIS WITH NO SIGNIFICANT NEURAL COMPROMISE..
Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear, situated in the vestibulum in the inner ear . As our movements consist of rotations and translations, the vestibular system comprises two components: the semicircular canal system, which indicate rotational movements; and the otoliths, which indicate linear accelerations.
1. few tiny foci of signal abnormality in the frontal white matter, stable since the prior exam. These are nonspecific and of uncertain if any significance. These could represent migrain related lesions.
2. relatively small lateral and third ventricles. This may be a normal variation. The possibility of a psuedotumor cerebri should be considered. Please correlate with clinical findings and fundal examiniation.
3. minimal mucosal inflammation disease in the right mastoid.
did you mean like a flushing sound,or you can call it whooshing sound of blood,like you can hear the pulse of you heartbeat?i am experiencing them,and i can hear it in my left ear. ct scan did not picked up anything but mri and angiogram gave the doctors a clearer view why.i have a left transverse arteriovenous fistula and it's a question if i have the cavernous arteriovenous fistula too,as my left eye was affected.
My question to you with respect, could the audiology part of the brain suffered some form of presure from the clamps and that this has caused Tinnitus, if so should I be concerned and ask the Tinnitus specialist for an MRI scan to maybe check for a Vestibular Schwannoma.
