| Summary: | An 11-year-old boy presented with painful swelling of leg following fracture of tibia. Osteo brous dysplasia (OFD) is an uncommon, benign, non-hereditary bone disorder in which brous tissue develops in place of normal bone that affects the young adults in their rst and second decade of life. Tc-99m MDP whole-body bone scintigraphy revealed increased tracer uptake in dense proximal tibia. On single-photon remission computed tomography-computed tomography (SPECT-CT), radiological features of cortical-based lesion superimposed on abnormal tracer uptake con rmed it to be a monostotic OFD. This case emphasises the role of SPECT-CT and magnetic resonance imaging in detecting osteo brous dysplasia and differentiating it from other benign bone conditions.
Key words: Bone scintigraphy, magnetic resonance imaging, monostotic osteo brous dysplasia, single-photon emission computed tomography computed tomography, tibia
