title: Scintigraphic depiction of non-ossifying fibromas and the role of SPECT/CT.
abstract: Non-ossifying fibromas (NOF) are a benign entity of the developing bone, relatively common in children and young adults. Their location is most frequently metaphyseal. They are usually asymptomatic (unless associated to a fracture) and have a self-limited behavior, with spontaneous regression through a sclerotic consolidation. Plain X-ray is the main imaging tool for its diagnosis. However, an unclear X-ray may lead to further imaging studies. We present the case of a 17-year-old male with back pain and lower limb dysmetria referred for a bone scintigraphy to complete the diagnostic and assess disease extension and the subsequent MRI evaluation.
