Arrested Pneumatisation of the Sphenoid Sinus: Important Normal Variants Not to be Overlooked

Abstract

An arrested pneumatization of the sphenoid sinus is an anatomical variation. It is understood that the sphenoid bones undergo early conversion of fatty marrow before normal pneumatization. Being a developmental condition, it typically occurs as an incidental discovery. The specific clinical symptoms associated with this condition cannot be attributed. They are usually observed as an incidental finding during radiological examinations. If not recognized, it can be easily mistaken for pathological lesions. The purpose of this article was to highlight this rare condition by examining the existing literature and presenting a case report.
