(👀 , 👅 and the 🧠)

The movement of the eyes and tongue is controlled by 𝗙𝗼𝘂𝗿 pure motor cranial nerves.
- The oculomotor (𝘾𝙉 III).
- The trochlear (𝘾𝙉 IV).
- The abducens (𝘾𝙉 VI).
- The hypoglossal (𝘾𝙉 XII).

* All four neuclei are located in the midline.
* All four nerves embrologicaly are somatic motor origin.
* All are pure motor and voluntary movement.

All are connected through internal fibers for better coordination of the eyes and tongue movement.

Cerebral arteriovenous malformation (𝗔𝗩𝗠) AVM Embolization: Pre- and Post-Treatment Angiographic Comparison

The left panel demonstrates a grade II cerebral AVM consisting of multiple 𝗠𝗖𝗔 feeding arteries, a compact nidus, and an early opacified draining vein, indicating high-flow arteriovenous shunting and absence of a normal capillary bed.
- Such hemodynamic stress predisposes to rupture and intracranial hemorrhage.

- Endovascular embolization was performed via superselective microcatheterization of the arterial feeders, followed by controlled injection of 𝗢𝗻𝘆𝘅 18—a low-viscosity ethylene-vinyl alcohol copolymer formulation—allowing deep nidus pe*******on and cohesive filling while minimizing reflux.

- The right panel, obtained post-embolization, reveals near-complete angiographic obliteration of the nidus and restoration of normal cerebral venous drainage patterns.

This illustrates the efficacy of liquid embolic agents in achieving durable flow reduction and preparing the lesion for potential surgical resection or stereotactic radiosurgery.

A carotid–cavernous fistula (CCF) 𝗮𝗻𝗱 𝗰𝗼𝗻𝗷𝘂𝗻𝗰𝗶𝘃𝗮𝗹 𝗰𝗼𝗿𝗸𝘀𝗰𝗿𝗲𝘄 !

- Abnormal connection between the carotid arterial system and the cavernous sinus, leading to high-flow shunting of arterial blood into the venous system.
- This elevated venous pressure causes congestion of the orbital veins, resulting in classic ocular findings such as:
* pulsatile proptosis
* chemosis
* conjunctival arterialization, often described as “𝗰𝗼𝗿𝗸𝘀𝗰𝗿𝗲𝘄” vessels.
^ These twisting, engorged conjunctival vessels reflect the high-flow state and impaired venous drainage seen in CCFs.

Brain Medial view of the deep structures - The 𝗔𝗻𝘁𝗲𝗿𝗶𝗼𝗿 𝗖𝗵𝗼𝗿𝗼𝗶𝗱𝗮𝗹 𝗔𝗿𝘁𝗲𝗿𝘆 (AChA) and the 𝗛𝗛𝗛 𝘀𝘆𝗻𝗱𝗿𝗼𝗺𝗲

Dissection demonstrates the anterior choroidal artery (AChA) arising from the internal carotid artery (ICA).
The AChA courses posterolaterally beneath the 𝗨𝗻𝗰𝘂𝘀, supplying the following:
1- Optic tract.
2- Posterior limb of the internal capsule.
3- Globus pallidus.
4- Lateral geniculate body.
5- Chroid plexus.

Classic 𝗔𝗖𝗵𝗔 𝗦𝘆𝗻𝗱𝗿𝗼𝗺𝗲 "𝗛𝗛𝗛" (Triad):
- described by Foix and Charcot-

1. Contralateral 𝗛emiplegia – corticospinal fibers in the posterior limb of the internal capsule.
2. Contralateral 𝗛emisensory loss – damage to thalamocortical sensory fibers traversing the same region.
3. Contralateral 𝗛omonymous hemianopia – from ischemia of the optic tract or lateral geniculate body.
