title: Aspergillosis: a nidus of maxillary antrolith.
abstract: We present a case of polypoid sinusitis with maxillary sinus antrolith, which is composed of Aspergillus species. Unlike most muddy or necrotic fungal balls, this first reported fungal antrolith is solid and extremely hard. Aspergillus served as a central fungal nidus associated with long-standing sinusitis, and poor sinus drainage could be a possible pathophysiology for the formation of a sinus stone. Aspergillosis infection should be considered in the differential diagnosis of a radiopaque paranasal sinus lesion. The endoscopic sinus surgery can be a reliable and minimally invasive method not only for the removal of the stone, but also for the restoration of ventilation and drainage of the diseased sinus.
