Malignant neoplasm of brain, unspecified [C71.9] / Muscle weakness (generalized) [M62.81], Reason for Study: ^Reason: further eval of hemorrhagic mets History: metastatic cancer, worsened LE weakness Evolving multifocal bihemispheric mainly hemorrhagic lesions are seen on today's scan.Right thalamic and right hippocampal lesions' maximum measured diameter of each lesion appear to be decreased and there are evidence of peripheral hemosiderin deposition indicate evolving ICH.However, the right posterior temporal lesion shows development of cystic cavity adjacent to enhancing area the left superior temporal lesion appear to be increased in size since prior scan.There is interval development of right frontal burr hole with ventriculostomy tube inserted into the right lateral ventricle.There is no evidence of acute ischemic lesion.The ventricles, sulci and cisterns are 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. Some hemorrhagic lesions show MR characteristics of evolving ICH with interval decrease in size but some (right posterior temporal and left superior temporal lesions) demonstrate interval increase in size.2. No acute ischemic lesion.3. Stable ventricle size.
