Planning for stereotactic brain biopsy. Brain lesion. Enhanced head CT:75 cc of Omnipaque 350 was administered for this study.Enhanced axial 1 mm CT images of the entire brain were obtained for presurgical planning brain biopsy.Examination demonstrates diffuse lower density of bihemispheric white matter likely result of prior therapy. Multiple periventricular irregularly-shaped highly suspected calcific lesions similar to prior MRI examination from 8 -- 5 -- 11. There is suggestion of subtle enhancement of these lesions as well. There are no non-infused CT images for confirmation of calcification however the very high density of these lesions is highly suspected of calcification. Review of prior head CT from 5 -- 12 -- 08 demonstrated no calcification. Findings could represent posttreatment changes of patient's known lymphoma. Recommend non-infused head CT for further evaluation. When compared with prior recent MRI there is no appreciable change.
Multiple irregularly-shaped and highly suspected calcific lesions similar to prior MRI. Subtle enhancement of these lesions is present in. Please see above comments.
