Malignant neoplasm of ovary [183.0] / Secondary malignant neoplasm of brain and spinal cord(198.3) [198.3] / Other malignant neoplasm without specification of site [199.1], Reason for Study: ^Reason: Ovarian cancer with brain mets post radiation therapy. Overall metastatic lesions' maximum diameter and enhancing portions have been decreased since prior scan.Specifically, the right frontal lobe dural metastatic lesion shows significant size reduction of lenticular shaped metastatic lesion which now remained linear dural enhancement.The right frontal lobe middle frontal gyrus rim enhancing lesion shows significantly reduced enhancing portion since prior scan.Other parenchymal lesions including left frontal lobe just lateral aspect of left lateral ventricle frontal horn, right periventricular white matter lesion just outside of the right lateral ventricle occipital horn, and right cerebellar hemisphere all show decreased size since prior scan.There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and 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.
Interval decrease size of enhancing portion as well as size of dural and multiple brain parenchymal metastatic lesions as described above.No evidence of new enhancing lesion.No evidence of acute ischemic or hemorrhagic lesion.
