Presentation
Headaches and seizures.
Patient Data
There is an abnormal poorly enhancing well defined intra-axial lesion in the cortical and subcortical white matter of the left frontoparietal lobes. The lesion is seen as hypointense on T1W, hyperintense on T2W, and FLAIR with areas of water restriction on DWI.
Perilesional edema is noted.
No evidence of necrosis, hemorrhage, or calcification is seen in the lesion.
Mild mass effect is seen in the form of effacement of the underlying cortical sulci.
Few high signal foci in T2 and flair sequences at subcortical and periventricular white matter of both cerebral hemispheres depict microvascular ischemic events.
Post-treatment changes as craniotomy, area of malacia changes surrounded by gliosis along with left frontoparietal lobes are seen.
No obvious enhancing component at the site of surgery due to residual or recurrence of the known brain tumor is depicted.
A few high signal foci in T2 and flair sequences at subcortical and periventricular white matter of both cerebral hemispheres depict microvascular ischemic events.
The tumor was resected and the pathology report was compatible with low-grade glioma.
Case Discussion
The patient underwent resection of the left frontoparietal lesion and histopathology was compatible with low-grade glioma.
