5.8 (AP) x 3.4 (Tran) x 2.9 (cc) cm rim-enhancing mass within the anterior inferior left temporal fossa which appears to have a dural tail extending along the surface of Meckel's cave, suggesting that this is an extra-axial dural-based mass with probable intra-axial extension in the left temporal lobe. The mass demonstrates heterogenous predominantly isointense signal on T2 weighted imaging and is mildly hypointense on T1 weighted imaging. There is some reduced diffusion within the within the solidly enhancing components of the mass, compatible with hypercellular tumor. Transosseous extension of enhancement into the infratemporal fossa and into the deep aspect of the temporalis muscle with bony changes better seen on the CT. Scattered punctate foci of susceptibility artifact consistent with hemorrhage.
Associated vasogenic oedema and mass effect with deviation of the left middle cerebral artery anteriorly, minimal effacement of the left lateral ventricle and unchanged minimal midline shift to the right by approximately 5 mm with slight compression of the left cerebral peduncle and minimal left uncal herniation.
