An approximately 3 x 5.8 x 3.3 cm ovoid poorly enhancing altered signal intensity lesion involving the right inferomedial temporal lobe, involving part of amygdala, hippocampus and the uncus with minimal perilesional vasogenic edema \u2013 represents low grade diffuse astrocytoma (WHO grade I to II)
The lesion demonstrates T2-FLAIR mismatch at the central portion \u2013 which may suggest an IDH-mutant 1p\/19q non-codeleted diffuse astrocytomas
No evidence of significant mass effect or mid line shift.<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"
