Resumen
Objetivo

Los tumores hepáticos son infrecuentes en la población pediátrica. Entre los más frecuentes se encuentran el hamartoma mesenquimatoso y el sarcoma embrionario indiferenciado, de diferente estirpe, pero con similitudes de imagen. El propósito de este artículo es repasar los hallazgos característicos en las imágenes y sus diagnósticos diferenciales. La ecografía es el método inicial para su estudio. La resonancia magnética y la tomografía computarizada son útiles para una mejor caracterización tumoral y planificación quirúrgica.

Conclusión

El radiólogo debe estar familiarizado con las características de imagen de las diferentes patologías y evaluarlas junto a la edad, antecedentes personales y análisis séricos del paciente.

Abstract
Objective

Hepatic tumors are uncommon in pediatric patients. Among the most common of these uncommon tumors are mesenchymal hamartoma and undifferentiated embryonal sarcoma, which have different origins but similar appearance on imaging studies. This paper reviews the characteristic findings and differential diagnosis of these entities. Ultrasonography is the first-line imaging test to study these tumors. Magnetic resonance imaging and computed tomography are useful for further characterizing the tumors and planning surgery.

Conclusion

Radiologists need to be familiar with the imaging findings of the different disease entities and to evaluate them together with the patient’s age, personal history, and bloodwork.
