 There is a mass in the right temporoparietal lobe measures 4.0 x 4.5 cm in transaxial view and approximately 3.1 cm in craniocaudal view. There is a surrounding vasogenic edema with mass effect and compression of the right frontal horn, right occipital horn and the right temporal horn. There is also compression of the brainstem, and the edema extends to the right basal ganglia, right external capsule and the right cerebral peduncle. There is approximately 3.6 mm leftward midline shift. The mass has heterogenous T2/FLAIR hyperintensity with faint central T1 hypointensity associated with restricted diffusion and has homogenous thick peripheral enhancement. The center of the mass is not enhancing suggestive of central necrosis. There is right-sided uncal herniation.In addition, there is a small satellite enhancing lesion in the right temporal lobe that measures 8 x 8 mm in transaxial view and 7 mm in craniocaudal view with no definite edema that surrounds this mass. However, in the right aspect of these enhancing lesion there is a confluent edema that is contiguous with the edema over the large mass.There is no evidence of hemorrhage.
1.There is a mass centered in the right temporal lobe associated with mass effect and uncal herniation which has a necrotic appearance. It is associated with a small satellite lesion in the right temporal lobe. Differential considerations include primary neoplasm of the brain as well as metastatic disease.2.Right-sided uncal herniation.
