Recent right cerebellopontine angle tumor intracapsular debulking. There are recent postoperative findings related to right suboccipital and translabyrinthine craniectomy with fat graft obliteration for intracapsular debulking of a right cerebellopontine angle tumor. There is residual tumor within the cerebellopontine angle cisterns that measures up to 4 cm. There is also a small amount of tumor within the skeletonized right internal auditory canal. There are scattered areas of susceptibility effect within the residual tumor, which likely correspond to blood products, particularly along the surgical margins. There is associated mass effect upon the adjacent brainstem and right cerebellar hemisphere, with leftward displacement of the vertebrobasilar system, as well as partial effacement of the fourth ventricle, but no dilatation of the third and lateral ventricles. There is a small area of restricted diffuse and high T2 signal in the lateral right cerebellar hemisphere, which represents acute ischemia. The supratentorial brain is unremarkable. There is persistent swelling and subgaleal fluid, which may represent leakage of cerebrospinal fluid and/or seroma.

A small amount of hemorrhage is present within the residual tumor, which extends into the skeletonized right internal auditory canal.
