NF type 2, deafness, vestibular schwannomas. There are postoperative findings related to bilateral retrosigmoid and right parietal craniotomy. Redemonstrated are numerous supratentorial and infratentorial extra-axial masses, including schwannomas and meningiomas, which are not significantly changed. In particular, the right vestibular schwannoma measures 3.7 x 2.3 x 2.2 cm, previously 3.7 x 2.2 x 2.2 cm and the left vestibular schwannoma measures 1.6 x 0.7 x 0.6 cm, previously also 1.6 x 0.7 x 0.6 cm. The brain parenchyma appears unchanged with mild areas of edema associated with some of the meningioma, particularly at the cerebral convexities. There is no evidence of acute cerebral infarction. The partially imaged intramedullary heterogeneously enhancing lesion within the upper cervical spinal cord appears grossly unchanged and is compatible with an ependymoma.
1. No significant interval change in the extensive intracranial stigmata of neurofibromatosis type 2, including bilateral vestibular schwannomas.2. Partially imaged ependymoma within the upper cervical spine.
