Mucocele of a pneumatised uncinate process: first reported case.
OBJECTIVE
We report a unique case of a mucocele of a pneumatised uncinate process.


METHODS
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.


CONCLUSIONS
This patient's clinical, radiological and intra-operative findings illustrate how variations in sinus anatomy can pose a diagnostic challenge.
