Parafalcine melanoma metastases: headaches There are post-treatment findings related to laser ablation of a right superior frontal gyrus with interval evolution of the signal characteristics of the hemorrhage within the lesion and the adjacent lesion with surrounding subarachnoid hemorrhage and vasogenic edema. The small nodule within the bilateral occipital lobes and right precentral gyrus are better depicted on the prior MRI with contrast. There are a few scattered foci of nonspecific T2 hyperintensity in the cerebral white matter. There is no midline shift or herniation. There is no evidence of acute infarction. The ventricles and basal cisterns are normal in size and configuration. The skull, orbits, and scalp soft tissues are unchanged.
1. Post-treatment findings related to laser ablation of a right superior frontal gyrus with interval evolution of the hemorrhage within the lesion and the adjacent subacute hematoma or hemorrhagic metastasis with surrounding subarachnoid hemorrhage and edema, although assessment is limited by the lack of intravenous contrast. 2. Other subcentimeter intracranial metastases are better depicted on the prior MRI with contrast.
