RESUMO

INTRODUCCIÓN El granuloma eosinofílico (GE) es una patología infrecuente, sobre todo en adultos, que puede afectar la columna cervical. A pesar de la vasta literatura, esta enfermedad afecta principalmente a la población infantil, y no hay un consenso sobre el manejo en adultos. Con el objetivo de aportar conocimiento respecto a esta patología poco frecuente, se presenta un caso clínico de GE cervical en un paciente de 16 años, a quien se trató de manera conservadora, con buenos resultados y retorno completo a sus actividades. CASO CLÍNICO Un hombre de 16 años, seleccionado de rugby, consultó por dolor cervical axial persistente y nocturno de 6 semanas de evolución, sin trauma evidente. Al examen, destacó dolor a la compresión axial sin compromiso neurológico asociado. Los exámenes de tomografía computarizada (TC) y resonancia magnética (RM) revelaron lesión lítica en el cuerpo de C3 de características agresivas, de presentación monostótica en tomografía por emisión de positrones-tomografía computada (TEP-TC) compatible con tumor primario vertebral. Se decidió realizar biopsia percutánea bajo TC, para definir el diagnóstico y manejo adecuado, la cual fue compatible con células de Langerhans. Al no presentar clínica ni imagenología de inestabilidad ósea evidente o compromiso neurológico, se manejó con tratamiento conservador, inmovilización cervical, analgesia oral, y seguimiento estrecho. A los cuatro meses de evolución, se presentó con una TC con cambios reparativos del cuerpo vertebral y sin dolor, y logró retomar sus actividad habituales. CONCLUSIONES El diagnóstico de GE es infrecuente a esta edad, y se debe plantear entre diagnósticos diferenciales de lesiones líticas agresivas primarias vertebrales. Es necesario el uso de imágenes, y la biopsia vertebral es fundamental para confirmar el diagnóstico. Su manejo va a depender de la sintomatología, del compromiso de estructuras vecinas, y de la estabilidad de la vértebra afectada. El manejo conservador con seguimiento clínico e imagenológico es una opción viable.


INTRODUCTION Eosinophilic granuloma (EG) is a rare, tumor-like lesion, infrequently affecting the cervical spine, particularly in adults. Although vastly described in literature, this pathology mainly affects children, and there is still no consensus on its treatment in older patients. With the goal of contributing to increase the knowledge regarding this infrequent pathology, we present a case of a C3 eosinophilic granuloma in a 16-year-old patient, who was treated conservatively, with good results, including complete return to his previous activities. CLINICAL CASE a 16-year-old male, elite rugby player, presented with a history of persistent neck pain, mainly at night, with no previous trauma. Upon physical examination, he reported neck pain with axial compression of the head, without neurological impairment. Both computed tomography (CT) and magnetic resonance imaging (MRI) scan revealed an aggressive lytic lesion in the C3 vertebral body, a with monostotic presentation on positron emission tomography-computed tomography (PET-CT) compatible with a primary spine tumor. A CT-guided percutaneous biopsy was obtained to establish the diagnosis and provide the proper management. The results were compatible with Langerhans cells. As he presented no symptoms or imaging findings of evident bone instability, as well as no neurological impairment, the patient was treated conservatively, with a cervical brace, oral pain medication and close followup. A CT obtained after four months of treatment showed reparative changes of the C3 vertebral body; at this point, the patient reported no neck pain, so he was able to return to his previous activities. CONCLUSIONS Although an EG is rare at this age, it should be considered in the differential diagnosis of primary vertebral aggressive lytic lesions. Imaging and a vertebral biopsy are paramount to confirm the diagnosis. The treatment modality depends on the symptoms, the involvement of adjacent structures, and the stability of the affected vertebra. Conservative management including clinical and imaging followup is a viable option.

RESUMO

Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in adults. Its prevalence is increasing as a result of population aging. The diagnosis of DCM is often delayed or overlooked, resulting in secondary neurologic morbidity. The natural course of DCM typically presents as a gradual neurological deterioration, with symptoms ranging from muscle weakness to complete paralysis, with variable degrees of sensory deficits and sphincter dysfunction. Magnetic resonance imaging (MRI) and electrophysiological studies allow the assessment of spinal cord function and its structural damage to determine treatment and clinical outcomes. All patients with signs and symptoms consistent with DCM should be referred to a spine surgeon for assessment and tailored treatment. Those patients with mild DCM can be managed non-operatively but require close monitoring and education about potentially alarming signs and symptoms. Surgery is not currently recommended for asymptomatic patients with evidence of spinal cord compression or cervical spinal stenosis on MRI, but they require a structured follow-up. Patients with moderate or severe DCM require surgical decompression to avoid further progression. The objective of this review is to raise awareness of degenerative cervical myelopathy and its increasing prevalence as well as to aid non-surgical healthcare workers for a timely diagnosis and management of this disabling condition.

RESUMO

AO Type C Thoracolumbar fractures are the most complex and unstable spine injuries, with a high frecuency of neurological impairment. The goal of this study is to describe the clinical characteristics, management and outcome in worker’s compensation patients with type C AO thoracolumbar fractures that were surgically treated in our hospital between January 1994 and December 2004. We collected 88 patients, 68 of them had work related accidents. Four patients were discarded because of insufficient data. The median follow up was 58 months. Of the 64 patients evaluated (mean age 35.7 years), 94 percent were men. The most common mechanism of injury was height fall (41 percent). Associated injuries occurred in 80 percent of the patients (23 percent had another spine fracture). Neurological impairment was present in 64 percent, 22 percent had incomplete, while 42 percent had complete impairment. The majority of the patients presented a C3 AO thoracolumbar fracture (50 percent). The average preoperative time was 6 days (range 0-64). The mean time of surgery was 224 minutes (range 80-640). Only 9.3 percent of the patients required a complementary anterior approach. The median hospitalization time was 61 days (6-275) and the mean postoperative rest was 9.8 months (1.4-34). We had 11 acute complications and 6 delayed complications. Return to work occurred in 64 percent of the patients, while 59 percent was compensated. Among the patients presenting partial neurological impairment, 50 percent improved at least one degree in the Frankel scale.


Las fracturas tóracolumbares tipo C de la AO corresponden a las lesiones espinales más complejas e inestables, con una alta incidencia de compromiso neurológico. El objetivo del presente estudio es describir las características clínicas, manejo y evolución de los pacientes accidentados del trabajo, con fracturas tóracolumbares tipo C de la AO, operados en nuestro hospital. Revisamos en forma retrospectiva los casos entre enero de 1994 y diciembre de 2004. Recolectamos 88 pacientes, 68 de los cuales correspondían a accidentados del trabajo. Cuatro casos fueron eliminados por información incompleta. La mediana de seguimiento fue de 58 meses. De los 64 pacientes evaluados (edad promedio 35,7 años),el 94 por ciento eran hombres. El mecanismo de lesión más común fue caída de altura (41 por ciento). Un 80 por ciento de los pacientes presentaron lesiones asociadas (23 por ciento con fractura de columna a otro nivel). Un 64 por ciento ingresó con compromiso neurológico, de los cuales, el 22 por ciento fue parcial y 42 por ciento completo. La mayoría de las fracturas fueron tipo C3 de la clasificación AO (50 por ciento). El tiempo promedio preoperatorio fue de 6 días (0-64). La duración promedio de la cirugía fue de 224 minutos (80-640). Un 9,3 por ciento de los pacientes requirió de una vía anterior complementaria. La mediana de hospitalización fue de 61 días (6-275) y el tiempo promedio de reposo post operatorio fue de 9,8 meses (1,4-34 meses). Hubo 11 complicaciones precoces y 6 tardías. Un 64 por ciento retornó al trabajo y un 59 por ciento fue indemnizado. De los pacientes con compromiso neurológico parcial, un 50 por ciento recuperó al menos un grado en la escala de Frankel.
