Sphenoid sinus mucocele: case report of an appearance on a panoramic radiograph.

Mucoceles of the sphenoid bone are rarely seen, although many short reports have appeared in the medical literature since they were first described by Berg in 1889. The sphenoid sinus is located deep in the skull close to sensitive structures such as the optic chiasm and the upper 6 cranial nerves. Most sphenoid lesions are found through a variety of signs and symptoms, the appearance of which depends on the structure involved. A case of an incidental finding of a sphenoid sinus mucocele on a dental panoramic radiograph is described in a totally symptom-free 22-year-old woman. The screening of radiographs by a specialist in oral radiology plays a vital role in early diagnosis of a variety of diseases of the head and neck region.
