Abstract

This paper reports a useful application of 11C-methionine positron emission tomography (PET) in the detection of iatrogenic secondary tumor seeding in the biopsy track after a stereotactic biopsy in a metastatic brain tumor patient. Considering that gadolinium-enhanced magnetic resonance image (MRI) does not always offer definitive discrimination of tumoral enhancement with biopsy-related contrast enhancement, 11C-methionine PET may be a good diagnostic method for detection of iatrogenic secondary tumor seeding after stereotactic biopsy for a metastatic brain tumor, which usually needs prompt local treatment.
