 No significant change in appearance of the resection cavity in the right superior temporal gyrus. No significant change in extent of surrounding T2/FLAIR high signal. The cavity measures 23 x 20 mm, previously 23 x 18 mm. Linear as well as nodular areas of contrast enhancement along the posterior and anteromedial margins of the cavity are not significant changed. Restricted diffusion and intrinsic T1 shortening along the posterior surgical cavity wall are unchanged and compatible with posttreatment change. Dynamic susceptibility-weighted contrast-enhanced imaging shows no significant increase in relative cerebral blood flow in in the tissues surrounding the surgical cavity.The ventricular system remains mildly enlarged. Ex vacuo focal enlargement of the posterior body of the right lateral ventricle is also unchanged. Minimal periventricular T2 hyperintensity is unchanged nor the few tiny scattered foci of deep frontal white matter T2 hyperintensity. Major intracranial vessels are patent. The right parietal craniotomy flap and a minimal underlying extra-axial fluid are unchanged. There is bilateral lens replacement. The orbits are otherwise unremarkable. The paranasal sinuses and mastoid air cells are clear.
Compared to the previous examination of July 29, 2015, there is no evidence of interval disease progression.
