 A 7 x 7 mm intensely enhancing lesion is noted in the left precuneus with surrounding vasogenic edema causing mild sulcal effacement (series 12, image 42). An additional intensely enhancing lesion is visualized in the peripheral right inferior temporal gyrus measuring 6 x 6 mm (series 12, image 103). There is also mild surrounding vasogenic edema which causes mild sulcal effacement at this level. These lesions are compatible with small metastases. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. No diffusion-weighted abnormalities are identified. 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.No evidence of acute ischemia or intracranial hemorrhage.2.Subcentimeter enhancing lesions in the left parietal and right temporal lobes consistent with metastatic disease. There is surrounding vasogenic edema and mild local mass effect.
