Statistics

Aneurysm of the azygos vein is a rare cause of mediastinal mass that is normally detected radiologically in asymptomatic patients. In some cases a diagnosis is made by noninvasive methods, such as computed tomography and magnetic resonance. However, in the present case imaging revealed what appeared to be a solid mass. When the mass had been excised by thoracotomy, the histopathologic diagnosis was aneurysm of the azygos vein.

Key words:
Azygos vein
Aneurysm
Mediastinal mass

El aneurisma de la vena ácigos es una causa muy infrecuente de masa mediastínica y habitualmente se trata de un hallazgo radiológico en pacientes asintomáticos. Aunque en algunas ocasiones se puede llegar al diagnóstico por métodos no invasivos, como la tomografía computarizada y la resonancia magnética, en nuestro caso la imagen obtenida se asemejaba a una masa sólida. Se intervino a la paciente mediante toracotomía y se procedió a la exéresis de la tumoración. El diagnóstico histopatológico fue de aneurisma de la vena ácigos.

Palabras clave:
Vena ácigos
Aneurisma
Masa mediastínica
