Summary
A rare persistent primitive trigeminal artery was found in a patient with transient neurological symptoms and cleidocranial dysostosis. This finding highlights potential associations between vascular anomalies and genetic conditions.
Area of Science:
- Neuroscience
- Vascular Neurology
- Genetics
Background:
- Transient neurological deficits can mimic stroke but may arise from various underlying causes.
- Persistent primitive trigeminal artery is a rare congenital vascular anomaly.
- Cleidocranial dysostosis is associated with an increased risk of cerebral aneurysms and potential vascular anomalies.
Purpose of the Study:
- To report a case of transient neurological symptoms associated with a persistent primitive trigeminal artery in a patient with cleidocranial dysostosis.
- To discuss the potential link between genetic conditions like cleidocranial dysostosis and cerebrovascular anomalies.
Main Methods:
- Case presentation of a 29-year-old woman with acute neurological symptoms.
- Diagnostic work-up including computed tomographic angiography (CTA).
Main Results:
- The patient experienced transient right-sided weakness, numbness, and dysarthria.
- CTA revealed a persistent primitive trigeminal artery, a rare variant.
- Work-up excluded stroke and dissection.
- The patient had a history of migraine and cleidocranial dysostosis.
Conclusions:
- Persistent primitive trigeminal artery, though rare, should be considered in the differential diagnosis of transient neurological events.
- Cleidocranial dysostosis may be associated with a higher prevalence of circle of Willis anomalies, warranting careful vascular evaluation.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:14Cranial Nerves: Types Part I
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.

01:22Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

01:19Veins of Head and Neck
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
