 Brain: There is redemonstration of postoperative findings from multiple prior craniotomies with areas of bilateral frontal and cerebellar hemisphere encephalomalacia. There is an unc hanged meningioma along the planum sphenoidale. There is decreased enhancement associated with a cystic lesion with associated susceptibility effect in the left cerebellar hemisphere, which is otherwise unchanged in size. There is no evidence of acute ischemia. The shunted ventricular system appears slightly smaller. There is an unchanged enhancing intraconal lesion within the lateral left orbit. There is a partially-imaged upper cervical spinal cord ependymoma and upper cervical spinal canal schwannomas. There are unchanged enhancing left parietal and right occipital scalp lesions. There is scattered mild paranasal sinus mucosal thickening.Internal Auditory Canal: There are postoperative findings related to bilateral retrosigmoid craniotomies. The residual components of the left vestibular schwannoma have not significantly changed in size. Likewise, the residual right vestibular schwannoma has not significantly changed in size. There is persistent enhancement within the bilateral labyrinthine structures. There is also no significant interval change in the left facial nerve schwannoma involving the geniculate ganglion and internal auditory canal. There are also smaller facial nerve schwannomas centered in the right geniculate ganglion, as well as in the right mastoid segment, which is unchanged. A punctate left cerebellomedullary cistern schwannoma is unchanged. There are grossly unchanged bilateral trigeminal nerve schwannomas.
1. Unchanged planum sphenoidale meningioma.2. Unchanged residual bilateral vestibular schwannomas and bilateral facial nerve and trigeminal nerve schwannomas, as well as a left cerebellomedullary cistern schwannomas.3. Decreased enhancement associated with a cystic left cerebellar lesion, which is otherwise similar in size.4. Unchanged scalp additional schwannomas.5. Partially-imaged upper cervical spinal cord ependymoma and upper cervical spinal canal schwannomas. 6. The shunted ventricular system appears to have decreased slightly in size.
