 There are 5 enhancing masses, 3 within the supratentorial brain, 2 within the infratentorial cerebellum:*Left lateral occipital lobe, heterogeneous enhancement, 23 mm AP x 19 mm transverse x 20 mm craniocaudal.*Left temporal occipital junction, homogeneous enhancement, 8 x 8 x 8 mm.*The right cerebellar hemisphere, heterogeneous enhancement, 35 mm AP x 37 mm transverse x 33 mm craniocaudal.*Left cerebellar hemisphere, heterogeneous enhancement, 35 mm transverse x 3 mm AP x 29 mm craniocaudal.*Tiny nodular enhancement right frontal lobe (image 25, series 1101)Significant vasogenic edema and mass effect is noted within the cerebellar hemispheres resulting in deformation and partial effacement of the fourth ventricle. The third and lateral ventricles are enlarged with T2 hyperintense findings suggesting transependymal CSF resorption from early hydrocephalus. Note is made of what appears to be bilateral, connatal cysts with right frontal horn coarctation. Additionally, there are few foci of T2 hyperintensity in the white matter, especially involving the right caudate head.The cerebellar tonsils are in normal position. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear.
1.There are 5 enhancing masses, 3 within the supratentorial brain, 2 within the infratentorial cerebellum, most suggestive of metastatic disease.2.Significant vasogenic edema and mass effect is noted within the cerebellar hemispheres resulting in deformation and partial effacement of the fourth ventricle.3.Findings suggestive of early hydrocephalus with lateral and third ventricle enlargement and a suggestion of CSF resorption.
