Take a look at this really remarkable ultrasound image, not so much for it immediate clinical utility, but for its rarity.

A patient presented with numerous self-inflicted cuts all over the body including bilateral extremities, torso, and neck. Arrived profusely bleeding, and clearly needs to go to the operating theater.

Ultrasound of the right neck reveals the classic appearance of air within the internal jugular vein. This is evident by the hyper-echoic reflections with “dirty” distal shadowing. It is not hypo-echoic as is commonly assumed, because air has a lower ability to conduct sound than tissue or fluid hence it shows up brightly with a “reflective” quality.

They patient under went surgery and did well.
