New metastatic breast cancer in the brain: altered mental status. There is an irregular, heterogeneously enhancing mass along the left superior frontal convexity, which measures up to approximately 6 cm in length and 2 cm in thickness. There is associated diffuse thickening and hyperenhancement of the adjacent dura. There is extensive vasogenic edema in the underlying let frontal lobe. There is no evidence of acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no mild midline shift, but no herniation. The major cerebral flow voids are intact. There are multiple irregular lytic and sclerotic foci in the calvarium and right mandibular condyle, and perhaps in the partially imaged upper cervical spine. There is mild maxillary sinus mucosal thickening. The orbits are grossly unremarkable.
1. An irregular, heterogeneously enhancing mass along the left superior frontal convexity, which measures up to approximately 6 cm in length and 2 cm in thickness likely represents a dural-based metastasis. 2. Multiple bone metastases.
