MRI: Changes secondary to radiation treatment. Signal
enhancement in the region of the tumor bed is suspicious for tumor
recurrence. Thallium SPECT: Intense focus of thallium
uptake in deep right temporal lobe. Tc-99m HMPAO SPECT:
Hyperemia corresponding to Tl-201 uptake in temporal lobe. There is a
second focus of hyperemia in the left anterior temporal cortex
without corresponding Tl-201 uptake.
Impression
Metastatic tumor focus. Anterior temporal hyperemia
may represent silent seizure focus.
