RESUMEN

Las técnicas de imagen tomográficas, tomografía computarizada (TC) y resonancia magnética (RM) se vienen usando cada vez de forma más frecuente, en sustitución o adición a la radiografía simple, para el estudio del dolor de espalda. El objetivo de este trabajo es realizar una revisión general de las manifestaciones en TC y RM del amplio espectro de enfermedades que pueden ser responsables del dolor generado en la columna vertebral. Este espectro abarca la enfermedad degenerativa, de la alineación vertebral, tumoral, inflamatoria e infecciosa. El conocimiento y la descripción exacta y uniforme de los hallazgos con dichas técnicas suponen un soporte fundamental para la toma de decisiones clínicas en los pacientes con dolor de raquis (AU)

The use of tomographic imaging techniques, computed tomography (CT) and magnetic resonance imaging (MRI), to complement or replace plain-film radiography in the study of spine pain is becoming more and more common. The aim of this paper is to provide a general review of the CT and MRI manifestations of the wide spectrum of lesions that can cause pain in the spinal column. This spectrum includes degenerative disease, malalignment, tumors, inflammatory processes, and infectious processes. Precise knowledge and accurate reporting of the findings at CT and MRI are fundamental for clinical decision making in patients with spine pain (AU)

RESUMEN

La displasia fibrosa (DF) es una enfermedad benigna del hueso relativamente frecuente, en la que existe un trastorno de la maduración del mesénquima óseo con sustitución del tejido lamelar de la cavidad medular de los huesos por un tejido fibroso anómalo. Su diagnóstico a menudo es un hallazgo casual al realizar estudios radiológicos o gammagráficos óseos por otros motivos ya que normalmente es asintomática. En ocasiones puede presentar complicaciones como deformidades, fracturas patológicas y excepcionalmente transformación maligna. El diagnóstico diferencial entre DF y neoplasia maligna puede ser complicado y llevar a un diagnóstico tardío de cuando ya existe degeneración sarcomatosa. En este contexto, la tomografía de positrones con 18F-fluorodesoxiglucosa (PET-FDG) puede ser de utilidad en el seguimiento de esta patología. Presentamos 2 casos de pacientes diagnosticadas de DF con sospecha de malignización de sus lesiones y a las que se les solicitaron estudios complementarios de medicina nuclear(AU)

Fibrous dysplasia (FD) is a relatively frequent benign disease of the bone in which there is a maturation disorder of the bone-forming mesenchyme where the lamellar bone marrow is replaced with abnormal fibrous tissue. Its diagnosis is often an accidental finding when X-ray studies or bone scans are performed for other reasons since it is usually asymptomatic. There may be complications such as deformities, pathological fractures and exceptionally malignant transformation. The differential diagnosis between malignancy and FD can be complicated and lead to late diagnosis when sarcomatous degeneration already exists. In this context, the positron tomography with 18F-fluorodeoxyglucose (FDG-PET) may be useful in the monitoring of this condition. We present two cases of patients diagnosed of FD with suspicion of malignization of their bone lesions who were referred to Nuclear Medicin(AU)

RESUMEN

La introducción de las técnicas de imagen tomográficas, fundamentalmente la tomografía computarizada (TC) y resonancia magnética (RM), ha conllevado una paulatina disminución en las indicaciones de la radiología simple, tanto en el número de pacientes como en la cantidad de proyecciones por paciente. Esto ha podido conllevar una menor atención al estudio y conocimiento de la radiografía simple de la columna vertebral en condiciones normales y patológicas.Sin embargo, la radiografía simple aún sigue siendo ampliamente utilizada en atención primaria y especializada. Por tanto, se mantiene vigente el conocimiento de la anatomía radiológica normal y de las manifestaciones radiológicas de los distintos procesos patológicos que afectan a la columna vertebral y que pueden ser responsables del dolor vertebral.El objetivo de este trabajo es realizar una revisión general de las manifestaciones en la radiografía simple del amplio espectro de patologías que pueden ser responsables del dolor generado en la columna vertebral. Este espectro abarca la patología congénita, traumática, degenerativa, tumoral, inflamatoria e infecciosa (AU)

The introduction of tomographic imaging techniques, fundamentally computed tomography and magnetic resonance imaging, has led to a gradual decrease in the indications for plain-film radiography, resulting in fewer patients studied and fewer projections for each patient. Consequently, plain-film studies of the spine have received less attention and radiologists are less familiar with the typical findings in normal and pathologic conditions of the spine.Nevertheless, plain-film radiography continues to be widely used in both primary and specialized care. Thus, radiologists still need to be aware of the normal radiologic anatomy of the spine and of the radiologic manifestations of the diverse pathological processes that can affect the spinal column and that can cause pain.The aim of this article is to review the manifestations on plain-film radiography of a wide variety of diseases that can cause back pain, including congenital, traumatic, degenerative, tumor-related, inflammatory, and infectious diseases and processes (AU)

RESUMEN

Fibrous dysplasia (FD) is a relatively frequent benign disease of the bone in which there is a maturation disorder of the bone-forming mesenchyme where the lamellar bone marrow is replaced with abnormal fibrous tissue. Its diagnosis is often an accidental finding when X-ray studies or bone scans are performed for other reasons since it is usually asymptomatic. There may be complications such as deformities, pathological fractures and exceptionally malignant transformation. The differential diagnosis between malignancy and FD can be complicated and lead to late diagnosis when sarcomatous degeneration already exists. In this context, the positron tomography with (18)F-fluorodeoxyglucose (FDG-PET) may be useful in the monitoring of this condition. We present two cases of patients diagnosed of FD with suspicion of malignization of their bone lesions who were referred to Nuclear Medicin.
