Epidural and Subdural Hematomas, and Subarachnoid Hemorrhage Mnemonic

These three types of brain bleeds are the highest yield to be able to recognize on board exams. Additionally, you definitely do not want to miss these on any patient.

In my studies, I always seemed to have trouble keeping the first two straight (epidural and subdural). I came up with this mnemonic to help me, and hopefully it will help you too.

EpIdural looks like an Ellipse and has a lucId interval.  

SuBdural is caused by Bridging vein rupture. The hemorrhage looks long and thin like a bridge. Bridges cross over areas like the hemorrhage crosses over suture lines.

SuBArachnoid is caused by Berry Aneurysm rupture. They cause a “Bad Ass” headache (aka “worst of life”).
