Abstract
- Cholesterol granuloma is usually found in chronic middle ear disease. However, it rarely occurs in the sinonasal regions and only a few cases have been reported in the literature. The etiology of the sinonasal cholesterol granuloma is not known yet, and the clinical manifestations are variable. The 78-year-old man complained of facial pain and toothache at first visit. The PNS CT had a homogenous isodense mass occupying right spenoid sinus and extending to right pterygopalatine fossa, infratemporal fossa and masticator space. The PNS MRI had characteristically high signal lesion at both T1- and T2-weighted images. The tumor was completely excised via transantral approach. Pathological confirmation was the cholesterol granuloma with fungal infection consistent with Aspergillus species. This patient is followed up without recurrence.
