Isolated sphenoid fungal sinusitis and vision loss: the case for early intervention
1Department of Otolaryngology, Shanghai Eye, Ear, Nose, and Throat Hospital, Fudan University, Shanghai, PR China.
Objective:
We report two extremely rare cases of isolated sphenoid 'fungal ball' in conjunction with vision loss.
Method:
Case reports and a literature review concerning diagnosis and management of isolated sphenoid fungal ball in conjunction with vision loss.
Results:
A mycetoma or fungal ball resulting from isolated sphenoid fungal sinusitis is a rare disease. It is frequently difficult to diagnose, as patients present with nonspecific symptoms such as headache, visual disturbance and cranial nerve palsies. Diagnosis of the disease is typically not made until advanced imaging has been performed. We present two cases of patients with sphenoid sinus fungal ball who developed headaches and vision loss. One patient had symptoms of IIIrd cranial nerve palsy and the other partial visual field impairment. After a timely sphenoidotomy, both patients recovered fully, with resolution of all symptoms.
Conclusion:
These two cases of sphenoid fungal ball in conjunction with vision loss suggest that the otolaryngologist should keep this disease in mind even when symptoms are nonspecific. Endoscopic surgery can be a safe and viable therapeutic approach for this condition.
Insights
Two rare cases of sphenoid fungal ball, a type of fungal sinusitis, caused vision loss. Prompt endoscopic surgery resolved symptoms, highlighting the need for early diagnosis of this rare condition.
Area of Science:
- Otolaryngology
- Ophthalmology
- Mycology
Background:
- Isolated sphenoid fungal ball (mycetoma) is a rare condition.
- Diagnosis can be challenging due to nonspecific symptoms like headache and visual disturbances.
Observation:
- Two patients presented with vision loss and headaches attributed to sphenoid sinus fungal balls.
- One patient experienced IIIrd cranial nerve palsy, and the other had partial visual field impairment.
Findings:
- Advanced imaging is often required for diagnosis.
- Timely sphenoidotomy led to full recovery and symptom resolution in both cases.
Implications:
- Otolaryngologists should consider sphenoid fungal ball in patients with nonspecific symptoms, including vision loss.
- Endoscopic surgery is a safe and effective treatment for this condition.
