[Abstract] Objective: To investigate the MRI features of fungal spherical rhinosinusitis and assess the extent of sinus involvement in patients, to improve the accuracy of preoperative diagnosis of fungal spherical rhinosinusitis.Materials and Methods: Retrospectively analyzed the clinical data, CT and MRI images of 24 patients with fungal sinus rhinosinusitis confirmed by operation and pathology. The characteristic imaging findings on MRI were mainly observed. The sinus involvement range was evaluated in combination with surgical records.Results: ①Of the 24 cases, 21 underwent CT scan and 24 underwent MRI scan. ②There were 23 cases of unilateral lesions and 1 case of bilateral lesion. ③There were 17 cases of unilateral sinus lesions (16 cases of unilateral maxillary sinus and 1 case of unilateral sphenoid sinus), and 7 cases occurred in multiple sinus cavities (2 cases involving maxillary sinus, ethmoid sinus and forehead sinus, 2 cases involving the sphenoid sinus and ethmoid sinus, 2 cases involving the maxillary sinus and ethmoid sinus, 1 case involving bilateral maxillary sinus and unilateral ethmoid sinus). ④CT scan showed that in 21 cases, the lesion sinus cavity was filled with uneven soft tissue density, 19 cases showed nodular, speckled, flocculent high-density calcification, and 2 cases showed no calcification. Of the 21 cases, 13 had sinus wall sclerosis; 12 cases had sinus enlargement, and 9 of them had partial bone resorption and destruction. ⑤MRI showed that the lesions were mostly located in the center of the sinus (15/24), partially in the sinus ostium (9/24), three cases had lesions in both place (3/24), the lesions showed a slightly lower to slightly higher signal on T1WI and a characteristic low signal on T2WI, the range of hypointensity area is larger than the CT calcification, the boundary of the low signal region is clear. In the affected sinus cavity, the mucosa thickened, T1WI showed equal or slightly lower signal, T2WI showed high signal; enhanced scan showed no enhancement of lesions and obvious enhancement of mucosa, the boundary of the lesion can be more clearly displayed.Conclusions: MRI multi-sequence imaging has great advantages for the display of fungal spheres, especially the characteristic low T2WI signal with a range larger than the calcification shown by CT. MRI can more accurately assess the extent of lesions and the involvement of adjacent tissues. It helps to improve the accuracy of preoperative diagnosis of fungal spherical rhinosinusitis.
