Grade 2 Astrocytoma

Findings:

Noncontrast CT images demonstrate a somewhat wedge shaped focus of low attenuation in the left frontal lobe with mild expansile characteristics suggested. The low attenuation is well defined. On the MRI images, a nonenhancing expansile mass is visible in this region which causes marked expansion of the middle frontal gyrus. Minimal FLAIR hyperintensity is seen along the margins of the lesion inferiorly.
