Abstract
Purpose: To review the pathophysiology, clinical features, radiological findings, and treatment of this rare disease.
Clinical findings: This report is about a 30-month-old child who is, to our knowledge, the youngest patient without cystic fibrosis with maxillary sinus mucopyocele. It is very unusual to see these problems in the pediatric age group.
Conclusion: Children with paranasal sinus mucocele or mucopyocele deserve screening for cystic fibrosis, even though it can occur in the absence of cystic fibrosis.
