摘要：

F-18-DOPA is a promising radiotracer used for both staging and restaging of primary brain tumors based on increased transport via the L-type large neutral amino acid transport system in tumor cells. Adult medulloblastoma is extremely rare. We present a case of 25-year-old man with posterior fossa medulloblastoma treated with surgery followed by chemotherapy and radiotherapy 5 years back, which later developed metastasis to left cerebral lobe treated with gamma knife followed by surgical debulking. Recent F-18-DOPA PET/CT demonstrates recurrence and disease progression on follow-up scan. F-18-DOPA PET/CT is extremely useful for characterizing brain tumors, response assessment, and prognosis.
