Magnetic resonance imaging and [11C]methyl-L-methionine positron emission tomography of fibrous dysplasia--two case reports.
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.
