Sinus mucoceles are epithelial lined cavities containing sterile mucus which develop as the result of an outflow obstruction of a sinus ostium. When containing pus, it is called a mucopyocele. They most commonly originate from the frontal and ethmoidal sinuses and can erode through neighboring structures such as the orbital walls. Large mucoceles can encroach into the orbit causing orbital or ocular symptoms that lead the patient to present initially to the ophthalmologist. Due to the large variety of symptoms on presentation, up to 47% of patients can be misdiagnosed on initial presentation with a delay of diagnosis for up to 520 weeks.
