Figure 1 SISCOM results. (A) SISCOM with preictal-injection SPECT shows hyperperfusion on the tumor lesion located at the left inferior-basal temporal area, ipsilateral midbrain, and thalamus. 99mTc-ECD injection was completed at 11s before the seizure began. (B) SISCOM with ictal-injection SPECT shows hyperperfusion at the ipsilateral amygdala-hippocampus, basal ganglia and pons. The 99mTc-ECD injection was completed at 25s out of a 47s seizure duration. (C) SISCOM with ictal-injection SPECT shows hypoperfusion at the tumor lesion and adjacent temporal lobe tissues. (D) A three-dimensional rendering view of the patient's brain MRI and tumor (blue color). *White arrows indicate the location of the tumor.
