Recurrent oligodendroglioma diagnosed with 11C-L-methionine and PET: a case report.
A benign oligodendroglioma was removed in a young patient who had temporal epileptic seizures. He then became free of any fit until 15 months after the operation, when he developed seizures progressively less controlled by therapy. All investigations were normal (including CT scan and MRI) except a PET study which showed a high uptake of 11C-L-methionine in the area of the previous tumor. The second operation revealed that this area was indeed a tumor recurrence. We briefly discuss the potential usefulness of PET for the follow-up of low grade gliomas.
