Secondary malignant neoplasm of bone [C79.51], Reason for Study: ^Reason: metastatic prostate cancer with skull metastasis History: metastatic prostate cancer Redemonstration of 24 mm x 30.5 mm x 7.7 mm sized left frontal bone sclerotic lesion without evidence of enhancement indicating metastatic sclerotic skull lesion, no change in terms of MR characteristics and size since prior scan. Specifically, there is no evidence of surrounding soft tissue lesion, no evidence of periosteal reaction.There is no evidence of abnormal enhancement.No evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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.
Stable left frontal skull sclerotic metastatic lesion since prior scan.Otherwise unremarkable brain MRI scan.
