The paranasal sinuses are composed of a set of structures of the maxillofacial region and its proximity to the oral cavity. The sphenoid sinus is located within the body of the sphenoid bone. However, an excessive pneumatization of this structure may cause difficulties in radiographic diagnosis, particularly with panoramic radiographs. This article describes a case of pneumatization of the sphenoid sinus in the pterygoid process and greater wing of the sphenoid bone, presented on a panoramic radiograph. Cone beam computed tomography in axial and coronal sections was performed to confirm the pneumatization of these structures.
