Article information

El aneurisma de la arteria subclavia es una entidad clínica infrecuente. Las principales causas son degenerativas y, menos frecuentemente, traumáticas.

Presentamos el caso de un trabajador de un aserradero que en una radiografía rutinaria de tórax mostró una gran masa ubicada en el lóbulo superior derecho. Los distintos estudios de imagen demostraron un aneurisma de 12,2×13,1cm parcialmente trombosado en la arteria subclavia derecha.

En nuestra experiencia, es preciso considerar esta causa de masa pulmonar, sobre todo de forma previa a adoptar actitudes diagnósticas (punción-biopsia) o terapéuticas invasivas, que pueden entrañar un alto riesgo para el paciente.

Subclavian artery aneurysm is a rare condition. The main causes are degenerative disease and, less often, trauma. We report the case of a sawmill worker with a large mass in the upper rigth lobe found in a routine X-ray. Imaging studies revealed the aneurysm to be 12.2x13.1cm, partially thrombosed and located in the rigth subclavian artery.

Our experience suggests that this cause of lung mass should be considered early in the diagnostic process, before undertaking invasive diagnostic (puncture-biopsy) or thera- peutic procedures that might place the patient at risk.

Key words:
