Metastatic prostate cancer with brain lesion: assess for disease status. There is a peripherally enhancing ovoid lesion with susceptibility effect and intrinsic T1 hyperintensity centrally, which measures up to 15 mm. There is no evidence of acute intracranial hemorrhage or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
A peripherally enhancing ovoid lesion with susceptibility effect and intrinsic T1 hyperintensity centrally, which measures up to 15 mm is nonspecific. The lesion may represent a previously hemorrhagic process, perhaps related to an underlying vascular tumor and less likely a metastasis, given that prostate cancer rarely metastasizes to the brain parenchyma. FOllow up imaging may be useful.
