71 year-old female with history of CVA in 2006. Breast cancer oblique radiation and now with (unreadable ward), MR presurgical evaluation No evidence of hemorrhage, edema, mass-effect, midline shift or hydrocephalus. A very small area of increased soft tissue density overlapping the ependymal lining of the right trigone is noted this finding measures approximately 6 mm times 7-mm on axial image 15. This finding is not associated with any edema and no definitive enhancement. Further follow-up with an MRI scan is recommended to exclude metastatic lesion.Calvarium, partially visualized paranasal sinuses and mastoid air cells remain within normal limits.
1. Localized increased soft tissue density on the ependymal lining of the trigon of right lateral ventricle is concerning for metastatic lesion and should be further evaluated with an MRI. Please see above comments. 2.Unremarkable CT examination of brain and calvarium otherwise.
