Female, 58 years old, with unspecified convulsions, status post laser ablation. Compared to 3/25/2016, there has been slight further evolution of postsurgical changes in the medial right temporal lobe related to prior depth electrode placement and laser ablation. There is susceptibility effect related to chronic blood products involving the right hippocampus with slight retraction/evolution since prior. Minimal surrounding FLAIR hyperintensity is seen which may represent gliosis. No significant parenchymal edema or mass effect is appreciated. Mild global parenchymal volume loss including of the left hippocampus again seen. No extra-axial collections. No hydrocephalus. Aside from postsurgical changes, calvarium and extracranial soft tissue structures are grossly unremarkable.
1. Slight evolution of postsurgical changes related to depth electrode placement and laser ablation of the right hippocampus. Chronic blood products in the right hippocampus are again seen with slight evolution.2. Please note patient had a minor contrast extravasation as detailed in the technique section and post gadolinium images could not be obtained. Patient may return for postgadolinium sequences following placement of a new IV line.
