Paranasal sinus mucocele in cystic fibrosis.
The relationship between cystic fibrosis, nasal polyposis and chronic sinusitis is clearly defined. Mucoceles of the paranasal sinuses, however, are a well-described complication of chronic sinusitis in adults; but they rarely occur in the pediatric age group. We report a three-year-old who presented with epiphora and fullness at the right medial canthus. Computed tomography confirmed a right ethmoid mucocele which was surgically drained, with resolution of symptoms. Approximately 12 other cases of mucoceles have been reported in the pediatric age group. Although many of these patients had recognized cystic fibrosis, some were previously undiagnosed. Only after presentation with a mucocele, did sweat testing reveal their underlying pathology. No pediatric patients in the literature were found with mucoceles and normal sweat tests. Paranasal sinus mucoceles may be diagnostic of cystic fibrosis and may be the presenting sign in some patients.
