Female, 49 years old, status post resection of a brain metastasis, status post whole brain RT, surveillance imaging. Postoperative findings are again seen compatible with resection of a tumor from the left frontal lobe. A small area of rim enhancement within the operative bed has further decreased in size. Mild surrounding edema persists.Numerous additional enhancing lesions both supratentorially and infratentorially are seen. A lesion along the posterior medial right temporal lobe has slightly increased in size from prior though it remains smaller than on earlier exams. Two subcentimeter foci of enhancement in the cerebellar vermis, and one slightly more laterally in the hemisphere, are new from prior and were not clearly present on pretreatment exams. A lesion in the left cerebellum is stable to minimally increased in size. A lesion in the left temporal lobe has probably not changed significantly.The above-mentioned lesions produce at most mild local edema. No significant generalized mass effect is seen. No abnormal extra-axial collections are detected. Ventricular size and morphology remain within normal limits. Mucous retention cysts are seen in the maxillary sinuses. A suspected calcified meningioma is redemonstrated at the left vertex along the posterior craniotomy margin.
1.Redemonstration of postoperative findings in the left frontal lobe without evidence of recurrent tumor.2.Multiple enhancing lesions are seen elsewhere supratentorially and infratentorially. When compared to the immediate prior examination, a lesion along the posterior medial right temporal lobe is slightly larger, and three small enhancing lesions in the cerebellum may be new.
