Breast cancer, evidence of brain metastasis, follow-up No evidence of acute ischemic or hemorrhage lesion.There are evidences of left frontal craniotomy including left frontal resection site with encephalomalacia and extra axial enhancement.Previously noted left inferior and superior frontal gyrus enhancing lesions appear to be slightly smaller than prior study, however, grossly no significant interval change in terms of MR characteristics and size.Multiple susceptibility artifacts on the left thalamus and right parietal lobe bilateral frontal lobe do not show any significant interval change since prior study.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. Post left frontal craniotomy with resection of tumor, no change since prior scan.2. Previously identified two enhancing nodules on the left frontal lobe superior and inferior gyri, do not show interval change in terms of size and MR characteristics since prior scan.3. No evidence of new ischemic or hemorrhagic lesion. No new abnormal enhancement.
