I've read a little bit about mucoceles;  don't know that much about
them, but I agreed this does require urgent surgical intervention.  If
you can't get emergyency surgery today, find out what kind of
antibitoics she his receiving.  Make sure that she is on something
broad specturm that would cover ANY infectious agent that could go to
her brain, and it has to be something that has good CNS and bone
penetration.   Don't just trust what the ER doctor has put her on.
When they first put my mother in the hosital at the end of June, the
first thing they did was give her Rocephin and she is allergic to
cephalosporins and had a bad reacton, even though it was clearly
written that she was allergic to them.  Then the 3rd time she was
admitted, they were about to give it to her again, just seconds before
I arrived and stopped them.  I woulnd't want to give any advice on what
antibitotics would be best; look up the one she is on and see what kind
of coverage it has.  Keep track of all of her blood work, especially
WBC and ESR.    You might want to keep in mind the possibility of a
fungal pathogen also.

Have they been able to get any kind of culture and sensitivities?  Have
they done a spinal tap?  I'm not sure the later would be in order, but
would be a consideraton if she starts running a high fever or blood
work becomes worse.  The benefits have to outweigh the risks.

Good luck!!

If the ER doctors on call think it's an emergency, they'll help you get
an ENT.  If not, hopefully she can hang in there till Monday.

What IV antibiotic is your wife on?  I think IV Cipro might be a decent
choice here.  Quinolones have broad coverage, and thanks to the
terrorist threat, just about every hospital stocks IV Cipro these days.
 (If the infection continues to get worse, then maybe they should use
the "last resort" IV vancomycin.)

I agree with kathywb2001 about an MRI scan.  But I can't understand how
even a CT scan could have missed a mucocele this big as to cause all
this trouble. When did your wife have her last CT scan?

Blindness in that eye, if the mucocele and associated infection
continues to invade the orbit of the eye.

Of course, the surgery now has a significant risk of blindness too,
since they're going to be operating so close to the eye and its optic
nerve.  So like I said, it's vital that you find a really experienced
ENT who can do this properly.  It's going to be trickier than the usual
removal of polyps and things that most ENTs routinely do for sinus problems.
