 BRAIN: There are unchanged postoperative findings related to suboccipital craniotomy for resection of right cerebellar medulloblastoma. There is minimal surrounding T2 prolongation surrounding the surgical cavity without significant change. There is no suspicious intracranial enhancement. There is no acute infarct, mass effect, or cerebral edema. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. There are mucus retention cysts in both maxillary sinuses. However, sinus opacification and mucosal thickening has overall markedly decreased from prior examination. The skull and extracranial soft tissues are unremarkable. SPINE: The vertebral body and intravertebral disk height are maintained. The marrow signal is unchanged with increased T1 and T2 signal, likely representing post treatment change. There is no acute fracture or subluxation. The conus medullaris terminates at L1-2. There is no suspicious enhancement within the spine.
Stable postoperative and post treatment findings without recurrent tumor or drop metastases within the spine.
