ABSTRACT
Rhabdomyosarcoma is the most common soft-tissue sarcoma in children; it can appear in any part of the body. Its biological behavior varies widely, and despite the absence of specific clinical or radiological characteristics, rhabdomyosarcoma should be taken into account in the differential diagnosis of solid tumors in children. This review focuses primarily on the imaging findings and anatomical distribution of the histological subtypes of childhood rhabdomyosarcoma and secondarily on the differential findings in histological studies.

El aneurisma de la vena ácigos es extremadamente raro, y cuando se localiza en el trayecto de una cisura pulmonar accesoria plantea un reto diagnóstico ya que puede confundirse con tumores originados en la pleura accesoria, como el tumor fibroso pleural solitario o el mesotelioma. El diagnóstico se debe hacer idealmente mediante métodos incruentos como la TC o RM con técnica angiográfica en varias fases, evitando así una intervención quirúrgica innecesaria. El caso presentado es excepcional dado que se trata del primero publicado en el que coinciden ambas situaciones clínicas, una cisura accesoria de la ácigos con un aneurisma venoso en ella (AU)
The saccular aneurysm of the azygos vein is an extremely rare condition, which when located in the path of an accesory pulmonary fissure, becomes a diagnostic challenge because it can be mistaken for tumors arising from the accesory pleura, like solitary fibrous tumor of the pleura or mesothelioma. The diagnosis should ideally be done by non-invasive methods such as CT or MR angiographic technique in multiple phases, thus avoiding unnecessary surgical intervention. This case is exceptional because, to our knowledge, it is the first to report both concomitant clinical situations, an aneurysm of the azygos vein in the pathway of its accessory fissure (AU)
