Figure 4.

A 63-year-old female with left frontal glioblastoma multiforme (previously treated); baseline scans (a), follow-up scans (b). Baseline single photon emission computed tomography-computed tomography revealed abnormal radiotracer uptake in the right parafalcine frontal lobe, which disappeared in the follow-up scan after receiving chemotherapy. Magnetic resonance imaging revealed an enhancing lesion in the same area, which became less enhancing in the follow-up scan. The patient subsequently deteriorated and died 13 months after the baseline scans. Positron emission tomography-computed tomography could not detect any abnormality in both the baseline and follow-up scans. Fused single photon emission computed tomography-magnetic resonance imaging shown for corroboration
