A 79 year old stumbled and sustained a minor head injury 2 weeks ago. He has become increasingly confused, drowsy and unsteady. He has a GCS of 13. He takes warfarin for Afib. What is the most likely dx?

The key is D. Subdural hematoma. [In elderly head injury usually leads to subdural hematoma

even if head injury is minor or trivial and extradural hematoma in elderly is extremely uncommon even

in more severe head injury. Warfarin is also a risk factor for subdural hematoma from a minor trauma.

Management: 1st line: Evacuation by barr hole craniostomy. 2nd line: Craniotomy if the clot is

organized. Up to 3 weeks burrhole may be possible but longer than this clot is mostly organized and Flap

craniotomy is usually required].
