Female, 61 years old, with assess for compulsive disorder, preoperative planning exam for laser fiber placement. Bilateral T2 hyperintense foci are redemonstrated adjacent to the frontal horns of the lateral ventricles representing sequelae of prior laser ablation. As before, the focus on the right is more conspicuous than the focus on the left. However, there has been no significant interval change in the size or morphology of these lesions. On postcontrast images, there is minimal enhancement at the left focus but no convincing enhancement on the right. Brain parenchymal morphology is otherwise unremarkable. No abnormal fluid collections are seen. Ventricular size and morphology are unchanged.
Expected findings are seen compatible with prior laser ablation adjacent to the bilateral frontal horns.
