Unusual metachronous presentation of bilateral frontoethmoid sinus mucoceles


A case report of a patient with bilateral frontoethmoid mucoceles with no obvious predisposing factors and each side presenting three years apart, with no ongoing nasal or paranasal signs of disease in the interim.

Bilateral paranasal sinus mucoceles have rarely been described in the literature; this case is unique, as it is the first description of a metachronous presentation. Additionally, the absence of any predisposing factors such as trauma, surgery or chronic sinusitis in either presentation is unusual.
