History of metastatic melanoma. MRI brain for RT treatment planning after ventriculostomy: headache. There is no significant interval change in the multiple intracranial metastases with associated vasogenic edema, including within the bilateral cerebellar hemispheres, left middle frontal gyrus, left superior frontal gyrus, and left hippocampal tail. There is confluent T2 hyperintensity surrounding the lesions. There is no evidence of intracranial hemorrhage or acute infarct. The ventricular system is unchanged. There is no midline shift or herniation. There is mild scattered subcortical and confluent periventricular white matter T2 hyperintensity without associated enhancement. The major cerebral flow voids are intact. The orbital contents are grossly unremarkable. However, there is a subcentimeter exophytic cystic lesion in the skin along the left lateral eyelid region, which may represent a hidrocystoma. There is an apical scalp lipoma that measures 7 mm in thickness. There are scattered paranasal sinus retention cysts.
Multiple supratentorial and infratentorial metastases with vasogenic edema, but no midline shift or herniation.
