Neuroradiology board review lecture 1 case 8

Neuroradiology board review. This lecture is geared towards the ABR core exam for residents, but it would be useful for review for the ABR certifying exam or certificate of added qualification (CAQ) exam for neuroradiology.

This case shows a right sided hyperdense extraaxial collection on a CT. This collection crosses sutures and has a crescent shape, suggesting a subdural location.

The diagnosis is: subdural hematoma

Subdural hematomas are extraaxial collections of blood which can be spontaneous or seen after trauma. Most commonly they are caused by bridging subdural veins. They have a high mortality and can sometimes require evacuation.
