Abusive head trauma is one of the most common causes of fatal head injuries in children less than 2 years of age. An intracranial pathology can exist even in the setting of a normal physical exam. A delay in the diagnosis of abusive head trauma can have serious life-threatening consequences on the child, as well as potential opportunities for maltreatment in the future.

Educational Goals / Teaching Points
To review traumatic subdural hematoma as well as various morpho-structural patterns of shearing injuries and thrombosis of intracranial bridging veins.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
1. Pathophysiology and imaging of traumatic subdural hematoma 2. Pathophysiology and imaging patterns of bridging vein thrombosis: a. Tadpole sign b. Simple tubular shape c. Lollipop sign d. Negative lollipop sign e. Positive compression sign f. Venous thrombosis secondary to trauma g. Rupture of the bridging vein

In abusive head trauma, there is a traumatic injury to the bridging vein with either partial or complete tear. This can secondarily result in thrombosis at the terminal end of the bridging vein with blood clots seen adjacent to the bridging vein. This work serves as a summary of patterns of imaging features of intracranial venous injury of AHT to facilitate familiarity and early detection of abusive head trauma in the pediatric population.
