Image of Metastasis and Radionecrosis on MRI and Contribution of PET to
the Differential Diagnosis - Case record Liščák R. 1 , Bělohlávek O. 2 , Vymazal J. 3 Oddělení stereotaktické a radiační neurochirurgie, Nemocnice Na Homolce, Praha, 1 |

Summary: Contribution of 18 F-fluorodeoxyglucose PET in neurological diseases including brain tumours is
solution of specific questions, one of which is differentiation of viable tumours after radiosurgery
or radiotherapy from radionecrosis. Authors presented a case report of a patient suffering from
epidermoid lung cancer and brain metastases. While the MRI displayed similar lesions, the 18 FDG
PET clearly showed the differences: the new cerebral metastasis corresponded to the focal increase
of glucose metabolism and histologically verified radionecrosis with an almost identical MR image
corresponded to a decreased glucose metabolism.
