Recent translabyrinthine resection of a left vestibular schwannoma. There are postoperative findings related to recent 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. There is a small amount of intrinsically T1 hyperintense material along the medial aspect of the resection cavity in the left cerebellopontine angle cistern, which may represent blood products and hemostatic material. There is also a thin curvilinear enhancing tissue in the anterior portion of the left cerebellopontine angle cistern resection cavity, which measures up to 7 mm in length, adjacent to the left trigeminal nerve root entry zone. There is a small area of partially imaged edema in the inferior left temporal lobe. The right temporal bone and internal auditory canal are unremarkable.
Postoperative findings related to recent left translabyrinthine resection of a left vestibular schwannoma. Thin curvilinear enhancing tissue in the anterior portion of the left cerebellopontine angle cistern resection cavity, which measures up to 7 mm in length may represent a small portion of residual tumor wall versus granulation tissue, for example.
