Mucocele of a pneumatised uncinate process: first reported case

Objective: We report a unique case of a mucocele of a pneumatised uncinate process. Method: Clinical, radiological and intra-operative findings are presented. Results: A 43-year-old woman was referred to our ENT department suffering from persistent symptoms of left-sided sinusitis. Although an initial computed tomography scan suggested a lacrimal duct mass, dacrocystography showed free flow through the nasolacrimal duct. The patient underwent surgery, revealing a mucocele within a pneumatised uncinate process. Conclusion: This patient's clinical, radiological and intra-operative findings illustrate how variations in sinus anatomy can pose a diagnostic challenge.
