Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: Pt w/ breast CA and brain mets. History: brain mets s/p SRS. 28 years Female (DOB:3/26/1988)Reason: Pt w/ breast CA and brain mets. History: brain mets s/p SRS.PROVIDER/ATTENDING NAME: RIMAS V. LUKAS RIMAS V. LUKAS Comparing to prior scan, there are nodular and somewhat linear enhancing lesions especially on the right cerebellar hemisphere, one at the inferior aspect and another at the superior aspect. Both are measured about 1 to 2 mm in diameter. There are not associated with surrounding edema. Comparing to prior scan, the mass size has been significantly decreased.Supratentorially, there is no identifiable enhancing lesion on today's scan.The CSF spaces are appropriate for the patient's stated age with no midline shift. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids of major intracranial vasculature are present.The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact. Opacification of the left maxillary sinus with mucosal thickening on the right maxillary sinus are seen.
1. Significant interval decrease of the size of the posterior fossa, especially on the right cerebellar hemispheric metastatic lesion since prior scan.2. Nonvisualization of previously seen enhancing metastatic lesion supratentorially.3. No evidence of acute ischemic or hemorrhagic lesion. No other abnormal enhancing lesion is seen.
