Azygos vein aneurysm is a rare cause of a posterior or paratracheal mediastinal mass. Trauma or conditions causing elevated flow or pressure in the azygos system, such as cardiac failure or cirrhosis of the liver are secondary causes of aneurysm of the azygos vein. We report a case of asymptomatic saccular aneurysm of the azygos vein in a 45-year-old man with blunt minor chest trauma. The azygos...

We report staged embolization and stereotactic radiation in a true adult choroidal vein of Galen malformation. Management dilemmas and their resolutions are also discussed.

The mammalian lung provides a system of airways in which inspired air is brought into intimate contact with the blood. As well as carrying out this essential physiological function, the hollow structure of the lung has enabled investigators to produce casts of the airways, the study of which has helped in the understanding of air movements within the lung. The dependence of higher forms of life...

Vein of Galen malformation (VOGM) is a rare congenital vascular malformation caused by the maldevelopment of its embryonic precursor, the median prosencephalic vein of Markowski. VOGM results in neonatal morbidity and mortality, and premature delivery does not improve the outcome. We report a term female neonate in whom a vein of Galen malformation was diagnosed prenatally at 37 wk of gestation...
