Ethmoid mucocele: a new feature of primary ciliary dyskinesia
Primary ciliary dyskinesia (PCD) is a rare congenital autosomal recessive disease that produces impairment of mucosal ciliary movement. Children with this disorder usually manifest recurrent and chronic infections of the upper and lower airways. We describe the history of a 12-month-old boy in whom the correct diagnosis of PCD was achieved after the occurrence of ethmoid mucocele associated with omolateral proptosis. A careful description of this new feature of PCD and its dangerous complications are also presented.
