Low-Grade Diffuse Astrocytoma

Last Updated: March 27, 2020

Figure 1: T1WI post contrast (left) and axial FLAIR (right) images demonstrate a fairly circumscribed infiltrative lesion involving the cortex and white matter. This low-grade tumor is associated with no appreciable enhancement.

Figure 2: Axial FLAIR (top row left) and coronal STIR (top row right) images demonstrate a poorly-defined infiltrative, hyperintense lesion involving the left temporal lobe, left insula and inferior left frontal lobe. T1WI after contrast administration (bottom) shows no contrast enhancement of this low-grade astrocytoma.
