Una fístula aortoentérica (FAE) es una comunicación aberrante entre la aorta y la pared del tubo digestivo. Se trata de una entidad rara pero con alta mortalidad que requiere, por tanto, un diagnóstico certero y precoz. Se clasifica como primaria si se desarrolla sobre una aorta nativa no intervenida previamente o como secundaria cuando ocurre en un contexto de complicación posquirúrgica de reparación vascular. Todo radiólogo debería saber reconocer los signos directos e indirectos que pudieran sugerir la existencia de una FAE. En este artículo se revisan los tipos de FAE y su correlación clínico-fisiopatológica, así como el algoritmo diagnóstico exponiendo los hallazgos radiológicos típicos en tomografía computarizada
An aortoenteric fistula is an abnormal communication between the aorta and the gastrointestinal tract wall. The high mortality associated with this rare entity means it requires early accurate diagnosis. Aortoenteric fistulas are classified as primary when they develop on a native aorta that has not undergone an intervention and as secondary when they develop after vascular repair surgery. All radiologists need to be able to recognize the direct and indirect signs that might suggest the presence of an aortoenteric fistula. This article reviews the types of aortoenteric fistulas and their clinical and pathophysiological correlation, as well as the diagnostic algorithm, illustrating the most characteristic findings on multidetector computed tomography

Los modelos de formación en radiología varían en la comunidad internacional. Es importante conocer las diferencias y los rasgos comunes entre los distintos países de cara a amoldarse a los cambios venideros y a seguir la tendencia de homogeneización internacional. Realizamos una revisión de los programas de formación de radiología en Europa, EE. UU. y Canadá y algunos países de Latinoamérica, incidiendo en el proceso de selección, la descripción del programa de residencia, la investigación, la obtención del título de especialista, la subespecialización y el mantenimiento de la certificación. Los resultados demuestran que existe una variabilidad significativa entre los distintos países aunque los territorios geográficos continentales tienden a asemejarse (AU)
Different models for training radiologists are used in different countries. Considering the trend toward international homogenization, it is important to know the differences and common traits among different countries to enable us to adapt our programs to future changes. We review training programs in radiology in Europe, the United States, Canada, and some Latin American countries. We focus on the selection process, residency programs, research, certification, subspecialization, and maintaining certification. We found a wide variability among countries, although there are more similarities within continents (AU)

Serous oligocystic or macrocystic adenoma of the pancreas is a very uncommon morphological variant of what was classically termed microcystic adenoma of the pancreas. This is a benign neoplasm; however, its radiological appearance mimicks that of potentially malignant mucinous neoplasms of the pancreas. Therefore, radiologists need to be familiar with this entity to ensure the most appropriate therapeutic management and help to avoid unnecessary surgery.

El adenoma seroso oligoquístico o macroquístico de páncreas es una variante morfológica muy poco frecuente del llamado clásicamente adenoma microquístico de páncreas. Es una neoplasia benigna cuya apariencia radiológica, sin embargo, recuerda a las neoplasias mucinosas de páncreas, con potencial maligno. El radiólogo debe, por lo tanto, estar familiarizado con esta entidad, con el fin de plantear el manejo terapéutico más apropiado y evitar en lo posible cirugías innecesarias (AU)
