Neoplasm of uncertain behavior, unspecified [D48.9], Reason for Study: ^Reason: brain mets History: metastatic thymic NE tumor with LE weakness Multifocal various sized skull lesions showing low T1, high or iso T2 with enhancement on Gad enhanced T1 images. There is no definitive evidence of adjacent inner or outer table invasion of each lesion nor associated scalp soft tissue mass. Constellation of these findings indicate possible multifocal skull metastasis.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. 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.
1. Multifocal various sized skull lesions suggesting multifocal metastatic lesions as described above. 2. No evidence of acute ischemic or hemorrhagic lesion. No intra axial abnormal enhancement.
