Female, 16 years old, with neurofibromatosis type II with brain tumors, acoustic neuromas, hearing loss in the left ear, pressure in the right ear radiating to the cheek. Postoperative findings are redemonstrated compatible with left occipital approach resection of a left IAC/CP angle lesion. Only minimal residual nonspecific enhancement is seen in the operative bed with no evidence to suggest progressive tumor.The partially enhancing right IAC/CP angle tumor has not significantly changed in size. The right cisternal trigeminal nerve remains thickened similar to prior. Tumor involving the right cavernous sinus and Meckel's cave seems to have slightly increased in size over multiple prior examinations, now measuring up to 25 mm in transverse dimension, previously 21 mm in 2013. Tumor involving the left cavernous sinus and Meckel's cave is probably not significantly changed.A minimally enhancing pineal region tumor measures 1 to 2 mm larger than on prior examinations, though this could in part reflect differences in technique. Tumor at the right occipital/C1 foramen has not significantly changed in size.No new intracranial lesions are seen. Prominence of the perivascular spaces with perhaps some mild associated gliosis in the right superior frontal gyrus is unchanged. Postoperative encephalomalacia in the left cerebellar hemisphere is also unchanged.
1.Stable postoperative findings compatible with left IAC/CP angle tumor resection.2.Stable right IAC/CP angle tumor.3.Slow interval increase in size of tumor involving the right cavernous sinus/Meckel's cave. No definite change in size of the tumor involving the left cavernous sinus/Meckel's cave.4.Pineal region tumor is stable to minimally increased in size.5.Right occipital/C1 foramen tumor is unchanged.
