"Crazy coworker stabbed her at her house." (Liver laceration with active bleeding, hemopneumothorax.) [Chest] [Hepatobiliary] [CT]

41 year old female who was stabbed through her right inframammary fold (aka under her right breast).

CT through 3 sequential phases shows a linear laceration through the right lobe of the liver. There is a small focus of contrast extravasation that enlarges over time, eventually spilling out of the liver into the peritoneal cavity. These findings are consistent with an AAST grade IV liver injury.

Oh, the knife also apparently went through the liver and diaphragm, into the chest cavity, because she also had a hemopneumothorax.

Her blood counts were trended and were stable, so she didn't need surgery for the liver laceration. She did have a chest tube placed for the pneumothorax.
