Abstract

A 71-year-old man with chronic rhinosinusitis presented with a purulent, foul-smelling nasal discharge and obstruction. One year earlier he had been treated with a dacryocystorhinostomy for nasolacrimal duct obstruction. During the procedure, bone wax had been used to control bleeding in the anterior upper nasal cavity. On computed tomographic imaging, a fat-density lesion was seen in the anterior upper sinonasal cavity and was found to be hypointense or signal-void on all magnetic resonance imaging sequences. The lesion, which proved to consist of bone wax, was surgically removed. Here, we present the imaging features of retained bone wax in a patient with clinically diagnosed chronic rhinosinusitis after dacryocystorhinostomy.
