 There are unchanged postoperative findings related to resection of a right vestibular schwannoma. There is an unchanged subcentimeter focus of enhancement within the superior aspect of the right internal auditory canal as well as unchanged thin linear enhancement along the posterior aspect of the right internal auditory canal. There is unchanged clumping of the right cranial nerve 7 and 8 complex. The left internal auditory canal is unremarkable. The bilateral inner ear structures are unremarkable. Partially imaged remainder of the brain demonstrates no intracranial mass or mass effect. Mild scattered paranasal sinus opacification similar to prior.
Continued stable appearance of small enhancing focus in the right superior internal auditory canal, which may represent a small focus of residual tumor versus granulation tissue.
