Clinical question: Metastatic prostate and renal cancer, evaluate brain lesions. Signs and symptoms: As above. Pre and post enhanced brain MRI:Examination redemonstrated few scattered tiny enhancing metastatic lesions in the parenchyma and superficially of bilateral cerebral hemispheres. There is no convincing evidence of any interval change in the size or number of lesions since prior exam. Also similar to prior exam none of the lesions demonstrate any appreciable surrounding edema or mass effect.Small foci of calvarial enhancement also remains nearly identical to prior study.Unremarkable cerebral cortex, cortical sulci, ventricular system and CSF spaces and maintained midline.Unremarkable images through the orbits and including axial fat sat post enhanced series.Paranasal sinuses and bilateral mastoid air cells demonstrate normal pneumatization signal pattern.
1.No evidence of an acute or new findings since prior study.2.Stable tiny scattered metastatic lesions in size and number without evidence of edema or mass effect.3.Stable small foci of calvarial enhancement since prior exam.
