 This exam is mildly degraded by susceptibility artifact, including the thin section post-contrast images through the IACs. The internal auditory canals are symmetrical and normal in size. The inner ears are normal. There is no evidence for mass, abnormal enhancement, or vascular anomaly. There is a right maxillary sinus retention cyst and mucosal thickening within the right sphenoid sinus.
Normal internal auditory canal MRI.
