Can a CT scan pick up an acoustic neuroma?

Can a CT scan pick up an acoustic neuroma?

Not usually: Ct scans use x-rays and are better for imaging bones than soft tissue. A large acoustic neuroma may be seen on ct scan, but MRI with a contrast medium is able to detect small acoustic neuromas that may only be several millimeters in size. Mri uses a magnet for imaging which also has the benefit of no x-ray exposure. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Can you tell me about acoustic neuroma?

Can you tell me about acoustic neuroma?

Benign tumor: Acoustic neuroma is a benign tumor that usually originates from the vestibular (balance) nerve. Treatment options include observation, surgery, or radiation depending on the symptoms, age of the patient, and growth of the lesion. See a neurotologist for full evaluation or a neurosurgeon that deals with these lesions on a regular basis. ...Read more

How do doctors diagnose acoustic neuroma?

Function/Imaging: Modalities can typically be divided into two categories:

1.) imaging - ct or MRI (with contrast) can be used to visualize tumors in detail.

2.) functional tests - audiometry and brainstem auditory evoked responses assess the integrity of the vestibulocochlear cranial nerve by analyzing how the brain responses to test sounds. ...Read more

Could an acoustic neuroma explain my severe headaches and neck pain?

Could an acoustic neuroma explain my severe headaches and neck pain?

Rarely: Acoustic neuromas would very infrequently cause neck pain and would only cause headache if very large. Acoustic neuromas usually present with ringing ing in one ear and hearing loss in one ear. ...Read more

I have unilateral tinnitus from about 4 months, feel a little unsteady sometimes. No hearing loss. Worried abt Acoustic neuroma, is it common?

No, but.....: Acoustic neuroma isn't common but it happens and it is serious. Your symptoms are worrisome. In any case you need to see a doctor about your symptoms. You can start with a primary care physician who will refer you to the appropriate specialist for further evaluation. Please don't procrastinate! ...Read more

My Recent MRI showed a 10mm ovoid cyst in the left basal ganglia - should I be concerned? I also have a 4mm acoustic neuroma on the right side.

Careful followup: You have two areas uncovered. The acoustic neuroma is the bigger issue, and needs to be carefully monitored and watched. If it gets bigger, it will require excision. Unclear why you have the cyst, but could represent a remote issue of no current consequence, but this too should be followed. Best to see an experienced neurosurgeon and set up plan of action. ...Read more

I've developed acoustic neuroma. What should I be watching out for in the future?

Several things: As acoustic neuromas grow they typically cause hearing loss and tinnitus. They may also produce balance problems. If they get very large they may cause facial nerve paralysis or hydrocephalus which is too much fluid pressure in your head. Fortunately, if it is closely monitored, most of the more serious complications may be avoided by surgical removal or radiation treatment. ...Read more

Are there treatment guidelines for acoustic neuroma?

Yes: Acoustic neuroma is usually managed by otolaryngology and neurosurgery. Small tumors less than 1 cm are usually followed with serial head mris. These tumors can be treated with radiosurgery or open surgery if they are growing or large and causing pressure on local structures. The loss of hearing means the surgical options expand somewhat. The main goal of treatment is to preserve facial function. ...Read more

Which treatment works the best and fastest for acoustic neuroma?

Microsurgery: The goal of treatment is to preserve neurologic function and cure the tumor. Microsurgery is highly effective. Facial nerve function can be preserved in ~95 % of patients if the tumor is < than 2cm but in less than 50 % if the tumor is > than 3cm. Radiosurgery is an alternative in tumors < than 3cm with local control achieved in~ 90%. You must see an experienced neurosurgeon in an experienced ctr. ...Read more

If an acoustic neuroma comes back, does that mean it’s a cancer?

Usually not: Recurrence usually means some tumor was left behind and not removed from the first surgery. This can occur if a lot was left behind (macroscopic residual, recurrence more frequent), or even a tiny amount was left behind (microscopic residual, recurrence less frequent). Malignant acoustics are extremely rare and most often occur after prior radiation treatment for a benign acoustic neuroma. ...Read more

Acoustic neuroma surgery - are there any common after effects?

Always: The size of the tumor dictates the chances of some problems from surgery. Most people that have surgery, are able to resume all their normal activities after a recovery period. Almost all patients will experience some vertigo following surgery that resolves over about 4-8 weeks. With larger rumors your chance of having temporary or permanent facial weakness increases. ...Read more

Acoustic neuroma surgery - does ENT or a neurosurgeon do the surgery?

Both: The national institute of health has recommended that acoustic neuroma patients be treated by a team of physicians including ENT and neurosurgery, because patient outcomes were better than when just one specialty was involved. Frequently both physicians will be involved with the surgery, depending on the chosen surgical approach. ...Read more
