Early cerebral venous drainage at embryo 21 mm long, changed from primary head sinus to newly formed dorsal venous sinuses. Dural covering is incomplete at this stage and tentorium cerebelli is formed soon.

Pituitary region anatomy. Picture I stumbled upon in and old presentation of mine for medical students. Basic, but liked it so thought I'd share. Love it when you can see the oculomotor nerves coursing through the cavernous sinus. #anatomy #radiology #pituitary #brain #USMLE

The #BrachialPlexus is a complex web of nerves which control the upper limb. All the information on controlling tone, complex movements, touch, pain and temperature regulation run back and forth through these nerves. All of these functions can be disrupted by injury.

External ventricular drains (EVDs) are one of the most common procedures in neurosurgery… And having to troubleshoot said EVDs that stop working (usually in the middle of the night) is ALSO common, though not always intuitive 📟🫠

Nice depiction of the 3⃣ clival divisions & their #neurovascular relationship: 🙂

✅ Upper = Sella turcica to Dorello’s canal.

✅ Mid = Inferior border of sphenoidal sella to level of the choana.

✅ Lower = Extends to the CCJ.

Think you know brain vascular anatomy? How many brain vascular circles do you know?

Everyone knows the Circle of Willis, but few know its venous counterpart: Venous Circle of Trolard, important in dural AVF

Can you see the polygon on top of a❤️? #medtwitter #neurotwitter #meded

#MorcosChallenge This is a petroclival meningioma. Petroclival meningiomas arise from petroclival fissure&grow medial to CN5. In comparision, petrous face meningiomas arise lateral to CN5, making petroclival meningiomas more operatively challenging #neurosurgery Eva Wu Journal of Neurosurgery
