Grade 2 astrocytoma diagnosed in 2009, status post RT/TMZ Again seen are postsurgical changes of prior left parietal craniotomy with biopsy tract extending into the left superior frontal gyrus. There is no significant change in appearance of masslike FLAIR hyperintensity involving the posterior aspect of the left superior frontal gyrus with additional also unchanged FLAIR hyperintensity involving the left precentral gyrus and extending deeper into the left hemispheric periventricular white matter. There is no significant enhancement. Multiple foci of susceptibility effect in the left frontal lobe remain unchanged.Again seen is a right posterior falcine dural based mass compatible with a meningioma and measures 16 x 14 x 17 mm in the AP by TR by CC dimensions and unchanged allowing for sampling error. The mass appears to encroach on the superior sagittal sinus. Additional nonspecific focus of FLAIR hyperintensity in the right superior frontal gyrus is unchanged. No significant intracranial mass effect, midline shift, or herniation. No hydrocephalus or extra-axial collections. Benign-appearing focus of enhancement involving the right frontal calvarium also remains unchanged. No suspicious calvarial lesions are appreciated.
1. Compared to 6/11/2014, there is unchanged appearance of the nonenhancing, expansile mass centered at the posterior aspect of the left superior frontal gyrus consistent with known low-grade glioma. No evidence of tumor progression.2. Stable right posterior falcine meningioma.
