Abstract

A 58-year-old woman, with a history of acute myeloid leukemia in complete response, was referred to the emergency department of our hospital for loss of consciousness. A brain MRI showed an intracranial mass suggestive for either primary brain tumor or brain metastasis. 18 F-FET PET/CT revealed increased uptake of the lesion. Metastasis from acute myeloid leukemia was diagnosed after brain biopsy. Whole-body 18 F-FDG PET/CT did not demonstrate other abnormal foci of 18 F-FDG accumulation, whereas brain lesion had an uptake slightly below the adjacent brain.
