Abstract

The purpose of this article is to evaluate the role of contrast-enhanced ultrasound in the characterization of non-traumatic focal splenic lesions.

Focal splenic lesions are less common than in other abdominal organs like the liver. Conventional ultrasound and Doppler ultrasound have a limited role in the characterization of splenic lesions, resulting in many of them unspecified.

Contrast ultrasound is an accessible, cheap, and safe technique which can help in the immediate characterization of lesions incidentally detected in the ultrasound examination, being a good alternative to others imaging techniques.

We review in detail the technique and the main indications. We also analyze imaging findings and enhancement pattern by using representative case of the main splenic lesions for both benign (epithelial cyst, cystic lymphangioma, hemangioma, hamartoma, infarction, sclerosing angiomatous nodular transformation, abscesses, sarcoidosis), and malignant (lymphoma, metastasis) and its pathological correlation in some cases.

Resumen

El objetivo del artículo es evaluar el papel de la ecografía con contraste en la caracterización de las lesiones focales esplénicas no traumáticas.

Las lesiones focales esplénicas son poco frecuentes en comparación con las hepáticas. La ecografía convencional y la ecografía doppler tienen un papel limitado en la caracterización de las lesiones esplénicas, resultando muchas de ellas inespecíficas. La ecografía con contraste es una técnica accesible, barata y segura que puede ayudar en la caracterización inmediata de las lesiones detectadas incidentalmente en el examen ecográfico, siendo una buena alternativa a otras técnicas de imagen.

Revisamos en detalle la técnica empleada, los fundamentos y principales indicaciones. También analizamos los hallazgos de imagen y el patrón de realce mediante casos representativos de las principales lesiones esplénicas tanto benignas (quiste epitelial, linfangioma quístico, hemangioma, hamartoma, infarto, transformación angiomatosa nodular esclerosante, abscesos, sarcoidosis), como malignas (linfoma, metástasis) y su correlación anatomopatológica en algunos casos.
