Radiation-induced medulloblastoma in an adult: a functional imaging study.
We describe functional imaging findings using MRI, 1H-Magnetic resonance spectroscopy and positron emission tomography in a case of radiation-induced medulloblastoma following radiotherapy for pineal gland tumor. MRS showed a prominent choline peak; FDG, 11C-Met and 11C-Choline PET showed a minimal glucose, increased methionine and choline uptake.
