Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, intractable, without status epilepticus [G40.219], Reason for Study: ^Reason: epilepsy History: seizures There is laser ablation probe inserted through the right occipital burr hole and the tip is located at the right mesial temporal lobe, hippocampus head.MRI with contrast enhancement shows tubular shaped enhancing cavity around the inserted probe indicating tissue with ablated area.There are linear enhancing lesions on the right temporal and occipital lobes indicating prior tracks of previously inserted probes through the right temporal and occipital burr holes. Sulcal effacement of the lateral aspect of the right temporal lobe are seen indicating postoperative changes.The ventricles, sulci and cisterns are unremarkable.
1. Right occipital burr hole approached laser ablation probe located at the right hippocampal head.2. Post enhancement scan shows tubular enhancement around the tip of the probe indicating post ablation changes.3. Additional linear to tubular enhancing areas around the temporal and occipital lobes indicate prior probe insertion track. No postoperative unusual finding.
