Abstract:
PURPOSE: To determine the usefulness of CT findings of an expansile ball-like high density mass in the differential diagnosis of fungal and nonfungal sinusitis. MATERIALS AND METHODS: Paranasal sinus CT findings in 62 patients (36 males and 26 females) with pathologically proven chronic paranasal sinusitis were retrospectively analyzed. Sinusitis was fungal in 21 patients (34%) and nonfungal in 41 (66%). Bone and soft tissue window settings were reviewed by two radiologists in terms of the presence, expansibility, bilaterality, and location of the ball-like high density mass, involved sinuses, bone thickening of the sinus wall, and associated calcification. RESULTS: The ball-like high density mass was more common in fungal sinusitis patients (81%), in whom it was expansile in 88% of cases and unilateral in 94% (p<0.05). In all patients, the mass was located in the maxillary sinus; in 88% of fungal cases and 90% of nonfungal, it was present in both its medial and lateral portions. Bone thickening (76%) and calcification (86%) were more common in fungal sinusitis (p<0.05). CONCLUSION: A ball-like high density expansile mass appears to be a valuable finding in the diagnosis of fungal sinusitis.
