|Patient: 51 year old male|
51-year-old man with long-standing history of seizure activity.
|DDx: DIFFERENTIAL DIAGNOSIS:|
Radiation necrosis, recurrent tumor, low- vs. high-grade brain neoplasm
Minimal FDG uptake within the right mesial temporal lobe that on MRI examination correlates to T2 hyperintense right mesial temporal enlargement, most likely representing low-grade tumor.
General Discussion: FULL HISTORY: |
51-year-old man with long-standing history of seizure activity. His last seizure activity was in June, 2006. An outside institution MRI examination performed on 7-3-06 was suspicious for infiltrating low-grade temporal lobe neoplasm. PET/CT study is requested for evaluation.
The patient underwent right temporal craniotomy for amygdala hippocampectomy and removal of mesial temporal tumor. Pathological examination showed Ganglioglioma; WHO Grade I
