 There are postoperative findings related to right parietal and temporal craniotomy for metastasectomy. There is hyperintense T2 signal abnormality in the treatment bed, which appears similar to prior. There are no areas of abnormal enhancement to suggest recurrence. There is encephalomalacia in the left parietal and occipital lobes, left basal ganglia and corona radiata, and right cerebellar hemisphere. There is ex vacuo dilatation of the left lateral ventricle. There are scattered foci of hyperintense T2 signal abnormality within the periventricular and subcortical white matter, which likely represent chronic small vessel ischemic disease. A punctate focus of susceptibility artifact in the left cerebellar hemisphere is compatible with a microhemorrhage. There is no acute infarct. There is mild fluid signal intensity within the right mastoid air cells. There are bilateral lens implants.
1. Post-treatment findings without evidence of recurrent or new intracranial metastases.2. Chronic infarcts in the left parietal and occipital lobes and left basal ganglia and corona radiata.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
