Translabyrinthine resection of a left vestibular schwannoma. There are postoperative findings related to left translabyrinthine resection of a left vestibular schwannoma. There is fat graft in the mastoidectomy bowl and cerebellopontine angle with a small amount of fluid in the subgaleal space posterior to the flap. The intrinsically T1 hyperintense material along the medial aspect of the resection cavity in the left cerebellopontine angle cistern has resolved and likely represented blood products and hemostatic material. The thin curvilinear enhancing tissue in the anterior portion of the left cerebellopontine angle cistern resection cavity, adjacent to the left trigeminal nerve root entry zone has diminished. However, there is now enhancement within the left cochlea. There is a small area of edema in the inferior left temporal lobe has resolved. The right temporal bone and internal auditory canal are unremarkable. There are a few small paranasal sinus retention cysts.
Interval postoperative findings related to left translabyrinthine resection of a left vestibular schwannoma without definite gross residual tumor. New enhancement within the left cochlea may be inflammatory in nature.
