Staphylococcus epidermidis isolated sphenoiditis: a rare cause of recurrent orbital apex syndrome

Isolated sphenoid sinusitis (ISS) is a rare condition that can lead to severe complications, with orbital apex syndrome (OAS) being an exceptionally rare manifestation characterized by visual loss and multiple cranial neuropathies. We report a case of a 41-year-old female presenting with recurrent OAS caused by a chronic Staphylococcus epidermidis infection of the sphenoid sinus. Despite extensive diagnostic workups and multiple surgical interventions, the patient experienced recurrent episodes of OAS, highlighting the challenges in diagnosis and treatment. This report emphasizes the pathogenic potential of S. epidermidis, typically considered a commensal organism, in chronic sinusitis and underscores the importance of a multidisciplinary approach in managing such complex cases.
