Abstract
Mucoceles and mucopyoceles are rare cystic and cavitated collections originating in the paranasal sinuses. They most commonly occur in the frontal and ethmoid sinuses. A mucocele contains mucinous secretions, whereas a mucopyocele is an abscess-like formation that also contains purulent material.
Risk factors for development of a paranasal sinus mucocele include prior surgery, trauma, radiation, and sinusitis.
Sphenoid sinus mucoceles comprise only 1–2 % of all paranasal sinus mucoceles.
Mucoceles comprise only 0.05 % of lesions treated in major transsphenoidal series.
Most commonly, sphenoid sinus mucocele and mucopyocele are iatrogenic conditions seen after transsphenoidal surgery for pituitary adenomas.
The mean age at diagnosis is 53 years.
