70 year-old female with metastatic breast cancer presenting with drowsiness and decreased concentration. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. There is redemonstration of abnormal low T1 signal abnormality with consequent enhancement in the medial right parietal bone which is largely unchanged (measuring 57 mm in both the axial and coronal plane). There is no underlying suspicious dural or parenchymal enhancement.Major flow-voids are preserved.Sella and orbits are grossly within normal limits. A small amount of fluid is visualized bilaterally within the maxillary sinuses. The remaining paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1. Unchanged abnormal right parietal bone marrow signal is consistent with metastasis.2. There is no evidence for brain metastases.
