Assessment of rhabdoid brain tumor by F-18 FDG PET, C-11 methionine PET and MRI.
A 28-year-old man with headache, nausea, and decreased vision had a left parieto-occipital tumor demonstrated by MRI. Postradical resection and histology showed a solid mass containing rhabdoid cells, 10% positive for Ki-67. After completing chemotherapy and radiotherapy treatment, follow-up MRI revealed possible tumoral recurrence. Cerebral F-18 FDG PET revealed no pathologic uptake, and C-11 methionine PET showed a pathologic low uptake. These findings suggested recurrence of a mild-grade aggressiveness tumor, which was confirmed by a second neurosurgical resection.
