How durable is your knowledge of dural lesions?
How’s your knowledge base of the skull base?
Know the difference between petroclival & petrous face? Middle fossa & middle sphenoid wing? Clinoid & clivus?
Here is a map of skull base meningiomas. How many do you know?
Recognizing a lesion is only the first step. Communication is the next step.
If you can’t accurately communicate where a lesion is located, then you have only done have your job.
When it comes to skull base meningiomas, high risk lesions are the medial lesions:
🔸Clinoid
🔸Cavernous sinus
🔸Tuberculum sellae
🔸Medial/incisural tentorium
🔸Clivus
I think of a cone coming up from the foramen magnum encompassing these lesions that I call the “cone of risk”!
Hopefully, this anatomy of skull base dural lesions with stay with you for the duration!
