Figure 2. Computed tomographic features of maxillary sinus fungus ball with intralesional hyperdensity (A), without intralesional hyperdensity (B), with periodontal bone loss (C), with exogenous dental filling material (D), with periapical lucency (E), and with penetrating dental implant (F).
Figure 3. Female-to-male ratio in each decade of age. Female predominance was seen in the maxillary sinus fungus ball (MSFB) cases, overall. The female-to-male ratio was highest at 51-60 years (2.02) and rose to 2.60 in cases of MSFB with intralesional hyperdensity (IH) in the same range of age. In contrast, female predominance was not seen in patients without IH on CT scan images. The difference was significant in the 51-60 and 61-70 years’ groups. *p<0.05,**p<0.01
