Obsessive-compulsive disorder [F42], Reason for Study: ^Reason: anterior capsulotomy ablation History: ocd Redemonstration of post laser ablation (bilateral anterior capsulotomy) status of the bilateral internal capsule and caudate nucleus head areas demonstrating restricted diffusion, susceptibility artifacts and surrounding edema.The size of those lesions and the extent of surrounding edema and appears to be slightly increased since prior scan.There are intra lesional enhancements, the extent of enhancing portion are bigger than prior scan. There is no other new ischemic or hemorrhagic lesion on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. 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 bilateral LASER ablation status.2. Interval increase in size and extent of post ablation lesions. In particular, the size of restricted diffusion, the size of susceptibility artifacts and the extend of surrounding edema and the Gad enhancing portion since prior scan.3. No other acute ischemic or hemorrhagic lesion is seen.
