Malignant Glioma can appear as a complex cystic
structure as noted on the left
Pictured at left is a
low grade glioma ( Pilocytic Cerebellar Astrocytoma) with noncontrast CT
on the left and axial T2- weighted MRI on the right.)

note that a glioblastoma (above) looks
more necrotic (gray area in the center, which contains dead or necrotic cells
|
|
A grade 3 glioma (sometimes called anaplastic astrocytoma) will have less necrosis in the center (compared to a grade 4 or glioblastoma) but still look more abnormal (more enhancement) than a low grade (grade 1 or grade 2) . Low grade gliomas often recur, and at the time of the recurrence are higher grade (see pic of grade 1 that at the time of recurrence was grade 3) another low grade oligodendroglioma with anaplastic features on MRI here and course calcifications on CT here |
Unfortunately a year and a half of drug therapy has not reduced the size of the tumor. In fact, it has grown significantly since the last MRI. The optic nerve is being compressed. It should be flat at the bottom. Without surgery she would lose her sight as the tumor grows. If it begins to bleed internally the tumor will grow very rapidly and Kirsten will be left permanently blind.
