 BRAIN: There are unchanged postoperative findings related to suboccipital craniotomy for resection of a right cerebellar mass. There is minimal unchanged T2 hyperintensity within the right cerebellar hemisphere surrounding the resection cavity and no abnormal enhancement. There is no evidence of acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is moderate paranasal sinus mucosal thickening that is new since the prior exam including the maxillary, ethmoid, and sphenoid sinuses. SPINE: The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. There is unchanged increased T1 and T2 hyperintensity throughout the central vertebral body bone marrow most compatible with posttreatment effects and increased yellow marrow. There is no significant spinal canal stenosis. The spinal cord displays normal signal and morphology with the conus terminating at L1-L2. There is no evidence of intraspinal mass or abnormal enhancement. The paravertebral soft tissues are unremarkable. There is asymmetric mild enlargement of the right renal pelvis and ureter, not present on the 2/9/2015 exam but similar to the 11/10/2014 exam.
1. Unchanged posttreatment findings without evidence of tumor recurrence within the head or spine.2. Nonspecific moderate paranasal sinus mucosal thickening that is new since the prior exam.3. Nonspecific mild asymmetric enlargement of the right renal pelvis and ureter that was not present on the 2/9/2015 exam but is similar to the 11/10/2014 exam. Findings can be correlated with renal ultrasound as clinically indicated.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
