Abstract

Two cases of fibrous dysplasia in the skull base bone appeared hypointense on T₁- and T₂-weighted magnetic resonance imaging, with accumulation of [¹¹C]methyl-L-methionine ([¹¹C]Met) on positron emission tomography (PET). Fibrous dysplasia is a benign bone disorder which is identified by its distinctive radiography, computed tomography, and bone scintigraphy findings. [¹¹C]Met PET may indicate the presence of viable tumor-like cells in fibrous dysplasia.
