RESUMO
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
Los fibromas no osificantes (NOF) son entidades benignas del hueso en desarrollo, relativamente frecuentes en niños y adultos jóvenes. Su localización más habitual es la metáfisis de los huesos largos, suelen ser asintomáticos (excepto si se asocian a una fractura) y normalmente se autolimitan, regresando espontáneamente mediante una consolidación esclerosante. La radiografía simple es la principal herramienta para su diagnóstico. Sin embargo, una radiografía dudosa puede llevar a la realización de otras pruebas de imagen. Presentamos el caso de un chico de 17 años con dolor de espalda y dismetría de miembros inferiores, remitido para la realización de una gammagrafía ósea con la finalidad de completar el diagnóstico y evaluar la extensión de la afectación, y la posterior valoración mediante RM
