71 years, Male, urothelial cancer to brain, RT planning. Recent resection of brain metastasis. Examination is limited to sequences for treatment planning. Compared to postoperative MRI dated 4/23/2016, there has been slight evolution of postsurgical changes related to tumor resection in the right frontal lobe. Precontrast T1-weighted images were not obtained with question of minimal residual enhancement along the medial aspect of the resection cavity better assessed previously. There are blood products filling the right frontal resection cavity. Small right extra-axial fluid collection has decreased. Extensive vasogenic edema in the right frontal lobe is again seen and slightly decreased in the interval. Mass effect including partial effacement of the right frontal horn is again seen. There is minimal leftward midline shift. No uncal herniation. No lesions elsewhere in the brain are appreciated.
1. Slight evolution of postoperative changes of resection of right frontal mass. Sequences are limited for treatment planning; better assessed on prior study are findings of no definite evidence of residual tumor with question of minimal residual enhancement along the medial aspect of the resection cavity. No lesions elsewhere in the brain.2. Slight decrease in extensive vasogenic edema in the right frontal lobe.
