- Mucor or aspergillous
- Overall uncommon
- Diabetic (in particular if poorly controlled), elderly and/or otherwise compromised hosts (e.g. chemotherapy, immune-modulating treatments)
- Persistent and progressive facial pain
- Fever and congestion
- Invasive infection suggested by neurologic symptoms: numbness, double vision, dilated pupil (e.g. if cavernous sinus involvement/thrombosis)
- High mortality as these organisms are rapidly invasive and hosts typically compromised
- May be quite ill as it's invasive
- Sometimes febrile, sinus area pain
- Sometimes evidence palatal or external necrosis over sinus
- Invasive infection suggested by neurologic findings: facial numbness, dilated pupil, impaired extra-occular movements, red eye (e.g. w/cavernous sinus thrombosis)
- Impaired trans-illumination of maxillary sinus (if affected)
- CT or MRI of face and head
