Low flow vascular malformation
Loading 
Findings
There is a large relatively well-defined heterogeneous mass along the left posterolateral wall of the chest measuring approximately 12 x 10 x 4 cm. The mass is composed of tissues which are partly isodense to muscle (most of the mass) and partly of fluid density (small component).
The mass is located in the subcutaneous and intermuscular planes, based mostly around the left latissimus dorsi.
There are few phleboliths within the mass. Superiorly the mass extends to the axilla. The mass does not extend into the pleural space. The part that is isodense to muscle appears to be composed of serpiginous structures, likely vascular channels.
On postcontrast images, there is no enhancement during the arterial phase.
On venous phase images, there is opacification of some of the serpiginous structures, with some fluid-contrast level filled pockets.
