Fungal Sinusitis despite negative CT scan?
by KimSb, May 06, 2007 12:00AM
My main symptom is a unrelenting tight forehead sensation that leaves me in a daze & hungover. It feels like I'm wearing a helmet that's way too tight & is just debilitating & miserable. It also causes neuro-cognitive deficits such as major brain fog. An ENT at an Academic hospital has diagnosed me with a Frontal Fungal Sinusitis infection, although I have a negative CT scan. He has tried immunotherapy, various antibiotics & antifungal nasal rinses to no avail. He said surgery is a possibility, but surgeon couldn't guarantee that sinus surgery would relief the constant tight forehead sensation.
My internist, ID MD, & Neurologist at the same hospital are stumped. Spinal tap, 3 brain MRIs, EEG, EMG, & a 2 full spinal MRI's all negative & yielded no answers. He tried Elavil, SSRIs, Imitrix, Topamax, & no relief. He's convinced it's not a migraine as it's perpetual, with no relief.
Is it possible to have Frontal Fungal Sinusitis infection with a negative CT scan? Can it be virulent & recalcitrant, if so, what is the best treatment? Should I be looking for other possibilities to diagnose this main problematic symptom?
Your suggestions would be most appreciated.

Dear Kim Sb
First of all, keep in mind that I am unable to diagnose you because I am unable to examine you, this forum is for educational purposes.
The symptoms that you describe of constant frontal tightness/pressure and confusion (brain fog) are non-specific, but are commonly seen in many disorders. It seems that you have had quite an extensive work-up already given the tests that you have listed in your post including MRI, EEG, spinal tap and trials on several good headache preventative medications (elavil, topamax), which are all things that I would have suggested as well. Based on the symptoms that you have described, I would be most suspicious of the fungal sinusitis as the cause of your symptoms. I would also make sure that your spinal fluid was examined closely for the specific fungus that was isolated form your sinuses, because it can spread from the sinuses to the spinal fluid easily. Sometimes it takes a sample of spinal fluid removed directly form the brain or upper spinal region (require neurosurgery) to obtain diagnostic results. You can have a fungal sinusitis with a negative CT, and I would follow you ENTs advice about possible sinus surgery.
If you are still unable to get answers, you may consider going to a major academic medical center to be re-evaluated in detail with a fresh perspective.
I hope this has been helpful.

My symptoms are similar to yours, except add on a never ending headache to the forehead tightness. Beleive me, I know what the forehead tightness is like...people thought I was crazy or depressed for a long time. Does it kind of feel like it's hard to raise your eyebrows? I was diagnosed with a benign bone tumor behind my forehead after much persistance, which was never brought to my attention by the first 2 radiologists who read my MRI. Of course I'm not saying that's what you have, in fact, odds are against it, but you never know, and this is what I have to offer you...
Yes, exactly. Drives me nuts. ENT did point out a deviated septum & enlarged turbinates. He said I need surgery for that but surgeon said it would help my forehead symtoms. Wouldn't my multiple MRIs have shown a bone tumor or irregular mass behind the forehead? Should I have the MRIs read again by a different specialist who looks specifically for bone tumors of the forehead?
Thanks for the suggestions
would or wouldn't help your symptoms?
The thing is...different radiologists may or may not decide to report every little thing. I know again, it does sound strange, but the first radiologist completely ignored the tumor despite the fact that it is blatently obvious to see...I don't know the real reason for these things, but I suspect it may have to do with a balancing act they play--it's benign, there's no edema, it's not going to kill him, so let's spare him the concern and extra testing--that's the only thing I could think of, but I may never know. It was not until I went to a teaching hospital that it was pointed out to me and now I have MRI every 6 months to follow up until I decide it's time for surgery if I can't stand the symptoms anymore. Though, I might be trying the nasal surgery first in the remote chance it would help my forehead tightness and headache...I have a constantly blocked nose too, so even if it doesn't work, it should help me with that.
I will ask the MD to look for any "insignificant" lesions or masses around the frontal sinuses or supra-orbital regions.
