Patient with gun shot to chest. What would you call the finding indicated by the arrow?
Pulmonary laceration
-The lung parenchyma has elastic recoil. When there is a laceration, the lung parenchyma retracts creating a cavity (sometimes with an air fluid level).
-laceration is surrounded by hemorrhage (contusion) with an associated small hemothorax.

Patient had cardiac arrest 3 days ago. What is this?
Cortical Laminar Necrosis
-Occurs when the brain is derived of nutrients (hypoxia, ischemic event, hypoglycemia, increased demand such as status epilepticus)
-Gyriform hyperattenuation on non-con CT and T1 hyperintensity on MRI. In very early stages can restrict diffusion. Can calcify in chronic stages
-Signal characteristics are from denatured proteins in dying cells in the vulnerable cortical layers, not hemorrhage.
