Combined (11)C-methionine and 18F-FDG PET imaging in a case of cerebral sparganosis.
A 35-year-old man presented with right lower extremity numbness and weakness. CT demonstrated an irregular left parietal hypoattenuation with a punctuate calcification. MRI revealed a T1 low signal and T2 high signal lesion with extensive surrounding edema. Gadolinium-enhanced MRI showed an irregular enhancing lesion. F-FDG and C-methionine PET both demonstrated high uptake in the left parietal lesion. Lesion SUV was 7.5 for F-FDG and 3.0 for C-methionine. Surgical pathology demonstrated cerebral sparganosis.

Delayed cerebral radionecrosis with a high uptake of 11C-methionine on positron emission tomography and 201Tl-chloride on single-photon emission computed tomography.
A 47-year-old woman, who 2.5 years previously had undergone resection of a malignant astrocytoma of the left temporal lobe followed by radiotherapy, was found to have a mass in the left frontal lobe. This showed high uptake of thallium-201 (201Tl) on single-photon emission computed tomography and 11C-methionine on positron-emission tomography, suggesting recurrent tumour. Histological examination of the resected lesion, however, revealed it to be radionecrosis. This case thus illustrates a diagnostic pitfall in the use of these investigations for distinguishing radionecrosis from recurrent malignant glioma.
