We reported two cases of multiple paranasal mucoceles, in which MRI was useful to choose the appropriate surgical approach. The first case was a 53-year-old woman, with right visual disturbance due to spheno-ethmoid mucoceles. CT showed a large mucocele in the right spheno-ethmoid sinus, which was closely associated with the right optic nerve. However, MRI could detect a small mucocele lateral to the large one and showed that the small one, but not the large one, involved the optic nerve. The surgical treatment with an endonasal endoscopic approach and navigation-assisted endoscopic drainage of both mucoceles was performed, resulting in complete recovery of visual acuity.<br>The second case was a 52-year-old woman with three paranasal mucoceles. CT showed two mucoceles in the right maxillary sinus. However, MRI showed that the lateral lesion was separated from the medial wall of the nasal cavity by two other medial lesions in the maxillary sinus. Surgical treatment was performed by an external approach and drainage of the three mucoceles was successful.
