Somnolence [R40.0] / Unspecified convulsions [R56.9], Reason for Study: ^Reason: edema or bleeding? History: somnolence. Redemonstration of posterior raising evaluation surgery for right corpus callosum. At least 3 round to ovoid shaped parenchymal lesion with the surrounding edema are seen. These lesions show restricted diffusion which is unchanged since prior scan. There are central as well as the periportal susceptibility effect of those lesions indicate blood products or hemorrhage.Mild effacement of right lateral ventricle frontal horn is seen.There is no evidence of midline shift or ventriculomegaly.There is no evidence of new acute ischemic or hemorrhagic lesion.The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Post LASER ablation status of right corpus callosum as described above.2. No significant interval change of MR characteristics of those lesions since prior scan as described above.3. No evidence of new acute ischemic or hemorrhagic lesion.
