Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: Metastatic Breast with brain lesion to L cerebellar;s/p WBRT 2008-2009 History: headaches, balance issues Redemonstration of the left cerebellar hemisphere which suggests metastatic lesions. Multifocal susceptibility lesions within bilateral frontal lobes and multifocal nodular and somewhat linear enhancing lesions are again seen and unchanged in their number and MR configuration.Previous craniotomy with underlying left frontal lobe encephalomalacia does not show any significant interval change since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable except ex vacuo changes of the left lateral ventricle frontal horn. 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. No change of left cerebellar enhancing lesion (13.7mm x 14.7mm) since prior scan.2. Other multiple enhancing lesions on the left frontal lobe as well as bifrontal susceptibility lesions do not show any significant interval change since prior scan.3. No change of postoperative change of the left frontal craniotomy site.
