Unique case of oligoastrocytoma with recurrence and grade progression: Exhibiting differential expression of high mobility group-A1 and human telomerase reverse transcriptase

Figure 1 Radiological scans and findings before each surgical resection. A: MRI scans at initial diagnosis suggestive of glioma; B: CT scans at first recurrence showing calcification indicative of oligo-component presence; C: MRI scans just before third surgical intervention; D: CT scans before last resection confirming increased calcification. MRI: Magnetic resonance imaging; CT: Computed tomography.
