Resumen

Objetivo: El objetivo de este estudio fue evaluar la capacidad de la tomografía computarizada (TC) para diferenciar entre el bazo accesorio intrapancreático (IPAS) del tumor neuroendocrino pancreático (PanNET).

Métodos: Dos radiólogos evaluaron retrospectivamente ocho IPAS y doce PanNET en la cola del páncreas. Los lectores asignaron un diagnóstico a cada examen y evaluaron la presencia o ausencia de nueve hallazgos tomográficos que podrían ayudar en el diagnóstico.

Resultados: El lector 1 presentó una sensibilidad de 0,83 y una especificidad de 1; el lector 2, una sensibilidad de 0,78 y una especificidad de 0,86. Tres de los nueve hallazgos de la TC resultaron estadísticamente significativos en los IPAS: la lesión presente en la superficie dorsal del páncreas, la lesión que mostraba el mismo realce que el bazo en la fase venosa, y el realce heterogéneo en la fase arterial.

Conclusiones: La TC permite diferenciar entre IPAS y PanNET con buena especificidad y sensibilidad. El IPAS refleja el realce del bazo y suele localizarse a lo largo de la superficie dorsal del páncreas.
