Background: There are many causes of pediatric ptosis. However, acute unilateral ptosis manifestation as a result of isolated partial oculomotor nerve palsy involvement caused by sphenoid sinusitis is unusual. This is a diagnostic challenge as we report an uncommonly documented case of bilateral sphenoid sinusitis in a 12-year old boy with unilateral acute ptosis as the only presenting sign.
Case report: The patient presented to our eye department with right upper lid ptosis for one day with no visual impairment, headache, nasal symptoms or other neurological deficit. Diagnosis of bilateral sphenoid sinusitis was made from a contrasted computed tomography of brain and orbit. He underwent emergency bilateral sphenoidotomy by the otorhinolaryngology team, which revealed frank pus from the left sphenoid sinus and inflamed bilateral sphenoid mucosa intraoperatively. After the third day of intravenous Amoxycillin-Clavulonic acid, his ptosis completely resolved and he was discharged without neurological sequelae.
Conclusion: A high level of suspicion is entailed for accurate diagnosis so that correct treatment can be inaugurated. Neuroimaging such as the CT and MRI are excellent modalities to help in such cases.
Conflict of interest: We declare that there are no conflicts of interest.
