Male, 54 years old, with stage IV melanoma and known brain metastases, reevaluate disease status. Numerous scattered lesions are demonstrated throughout the brain and cerebellum compatible with treated metastatic foci. All of these lesions induce strong susceptibility artifact, and a few show intrinsic T1 hyperintensity. None demonstrates any significant or convincing enhancement, and none is associated with significant parenchymal edema. No new lesions are suspected.Evidence of prior right parietal craniotomy is again seen with encephalomalacia in the underlying brain parenchyma, unchanged. Confluent periventricular white matter T2 hyperintensity is unchanged and may be related to prior therapy. No significant edema or mass effect is detected. No acute intracranial hemorrhage is seen. The ventricular system is stable and within normal limits for size.
Numerous lesions are redemonstrated compatible with treated metastatic foci. On comparison with the prior examination, there has been no significant interval change. Specifically, no new or growing lesions are suspected.
