May be an impending: Problem. Most of the time chronic inflammation is due to poor drainage of secretions, its accumulation leading to infection. Nasal decongestants may help you and see a ENT specialist to avoid future problems. ...Read more

Which test- cat scan or mri- is best at looking at sinuses? Had severe sinus inflammation show up on both, but which test has the most detail?

In most: Cases, CT is preferred, due to its superior delineation of bone detail versus MRI. Variations in the bony structure of the sinuses are often responsible for predisposing to sinusitis. ...Read more

A cat scan was done, and I went to an ent. He said I was suffering from silent sinus syndrome. Are there alternatives?

I don't know: I don't know what your doctor told you, but the treatment for this condition is surgical. So if you are looking for a nonsurgical approach the answer is "no". ...Read more

Can you have a sinus infection with no cold, drainage, cough? Cat scan showed severe sinusitis, only symptom is facial/head pain, now on meds

Yes: Usually treated medically with decongestants and antibiotics. If recurrent, you you might have mechanical blockage at osteo-meatal-complex and need surgery to promote drainage. See an ENT. ...Read more

Cat scan of sinus today showed thickening and a few cysts/polyps. Facial/headache for a month. Got Medrol (methylprednisolone). Anything else I can do for chronic sinus?

Cat scan of sinus today showed thickening and a few cysts/polyps. Facial/headache for a month. Got Medrol (methylprednisolone). Anything else I can do for chronic sinus?

Many things: But ideally you should review this with your ENT doc. Often interventions like nasal saline irrigation (sometimes with baby shampoo too as a surfactant), antibiotic or antifungal rinses (sometimes even oral antibiotics), and antileukotriene medications, and then in the long run, sometimes sinus surgery is necessary. ...Read more

About 10 years ago found through cat scan sinus cavities were double the size. To this day have nose bleeds and cluster headaches. What can help me?

See an ENT: The best way to establish whether or not your headaches (cluster) and nosebleeds are related to your sinuses is to see your local ENT and undergo a formal evaluation, tests and imaging. ...Read more

During a cat scan Dr said I had fluid in my mastoids behind ear. Recommended sudafed. Will that help? Does that mean I have a sinus infection?

During a cat scan Dr said I had fluid in my mastoids behind ear. Recommended sudafed. Will that help? Does that mean I have a sinus infection?

Not necessarily: Fluid can back up into mastoids related to inner ear problems with fluid and sometime infection. Infection in mastoid which can result in necrosis and bone involvement can have fluid in mastoid air cells as well. Sinus infections involve paranasal sinuses frontals (above eyes) ethmoids medial to orbits, and lateral to nose, and maxillary inferior to orbits. These are facial in location. ...Read more

Slight tingle in left hand (pink&ring)tingles in left foot too/ clean blood work and cat scan! Super nervous. I have been getting allergy/sinus headach?

Calm down: Don't let your nerves get the best of you. What body part got the cat scan and why?
I would see an orthopedist since there is hand and foot involvement and let them conclude if you have isolated nerve compressions i.E carpal and tarsal tunner syndrome or some radiculpathy more proximally i.E the back, or some systemic disorder. I do not think the sinus headache is related. Feel better. ...Read more

Is orbital CT scan and CT scan sinus the same?

Is orbital CT scan and CT scan sinus the same?

Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read more

Can a CT scan with no contrast always see a sinus issue or can it b missed for some reason?

Can a CT scan with no contrast always see a sinus issue or can it b missed for some reason?

Possibly: Ct scans of sinuses are generally very good tests to evaluate for sinus disease. However, all tests can have their faults. If there is still something wrong that fits into sinus disease then you may need to see an ENT and possibly get a scope. ...Read more

Ct scan shows as 'bilateral fronto ethimoid and maxillary sinus ' how it can be cured thru medicine or by operating?

Try medicine first: This ct shows probable infection in the sinuses (i say "probable" because you didn't include the whole report). This can usually be treated with medicines- antibiotics before you would consider surgery. You should see your primary doctor for help with this, and then an ENT doctor if medicine is not helping. ...Read more

Ct scan results: frontal sinus is aplastic. Can you tell me what this means?

Ct scan results: frontal sinus is aplastic. Can you tell me what this means?

Normal variant: When your sinuses form they are typically filled with air and are lined with mucosa. Frontal sinuses, as well as, others may not form or they form incompletely. Aplastic is a term that describes an underdeveloped structure. ...Read more

I have sinus disease and benign maxillofacial sinus CT scan. What does that mean?

Sinus dx nl ct: It is hard to have sinus disease with a normal cat scan. You may have gotten a reading of benign findings. Basically this means it is negative for any masses or lesions. When you have a negative cr scan and nasal issues it is time to look elsewhere for abnormalities. I would check your allergies see an ENT or allergist and get worked up for this. Good luck and feel better! ...Read more

Should I worry if I've had sinus pressure for 3+ months even though CT scans show nothing wrong?

Yes but: First, do you have any nasal congestion? If yes, relieving the nasal congestion may be the answer. If not, one would need to look for other causes since sinusitis is unlikely to be the reason with the normal CT sinus results. Any added stress or job change in the past several months. ...Read more

Nothing without Sx.: To discuss your CT scan findings, we need to know 1) your symptoms & 2) working diagnoses. The doctor who ordered the CT scan knows both. Use Prime if you want to discuss on HealthTap. Literally: the "maxillary sinus" is the air space beneath the cheekbone. "Frothy" refers to air bubbles in a fluid (mucus), seen in the lower (gravity-"dependent") portions of the sinus. Sinuses normally make mucus. ...Read more

I was told after a ct scan that I have a underdeveloped sphenoid sinus. I don't see my dr until next week. How common is this & what r the complication?

I was told after a ct scan that I have a underdeveloped sphenoid sinus. I don't see my dr until next week. How common is this & what r the complication?

It is relatively: Common to have developmental variations of one or more of the sinuses. Usually there is no clinical significance. It may be important to a surgeon if there is a need for surgery in the region. There is some association of sinus hypoplasia with cystic fibrosis and other skeletal anomalies, but more than likely it is just an incidental finding. ...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
