Abstract:
This study reported a case of an arachnoid cyst of the sphenoid bone causing orbital signs and symptoms in a 58-year-old man with progressive proptosis and nonspecific discomfort in the OS. Orbital MRI showed a 3-cm homogeneous cyst within the left greater wing of the sphenoid bone. To the best of our knowledge, this is the first report of an intradiploic arachnoid cyst in the sphenoid bone with atypical radiological features, causing clinical symptoms, and managed through an eyelid approach, achieving a complete resolution with no complications.
