Male, 42 years old, with AVM planning for resection today, previously treated with radiosurgery in 2011. Again seen is a cystic focus with scattered surrounding patchy enhancement within the left post central gyrus, all appearing similar to the prior examination and likely corresponding to the site of the previously treated AVM. The degree of surrounding T2 hyperintensity is also unchanged.No new enhancing or nonenhancing parenchymal lesions are seen. Cerebral morphology is otherwise unremarkable. No new pathologic fluid collections are seen. The ventricles are stable in size. Non-fusion of the cerebellar vermis and nodulus with associated contour asymmetry of the fourth ventricle is unchanged and likely developmental.
Limited examination for surgical planning purposes redemonstrates the treated AVM in the left postcentral gyrus.
