A case is reported of a patient with nocturnal myoclonus and weakness of the left arm in whom a round defect was seen in the arch of C2 on the left side. Vertebral angiogram revealed that this was caused by an anomalous course of the vertebral artery and not by an aneurysm. A similar location of this foramen was found in nine of 100 cases reviewed.

A case of occipital artery originating from the vertebral artery.

Anomalies of the vertebral artery (VA) and its branches are rare but critical in neurovascular procedures. In a 38-year-old female, digital subtraction angiography revealed an anomalous origin of the occipital artery (OA) from the V3 segment of the left VA, with a tortuous course supplying the neck and scalp. Below the OA's origin, the suboccipital artery of Salmon arose, bifurcating into two branches.

Article Synopsis
- - The study focuses on a rare case where a patient's left vertebral artery originates from the left external carotid artery, highlighting its embryological background.
- - The case involved a 55-year-old male with sepsis who underwent CT and CT angiography, revealing a unique vertebral artery anatomy, while his right vertebral artery was underdeveloped (hypoplastic).
- - The findings indicate that such anatomical variations are usually asymptomatic but are important for medical professionals to recognize for accurate diagnosis and effective treatment planning.

Article Synopsis
- Neurosurgery in a semi-sitting position has benefits for some procedures, but it can increase the risk of venous air embolism, especially in patients with specific heart defects.
- Two young patients with congenital heart defects were evaluated using transesophageal echocardiography to identify potential right-to-left shunts before undergoing surgery for vestibular schwannoma.
- Perioperative echocardiography is crucial for detecting potential complications and determining if a semi-sitting position is safe, but surgical teams must be prepared for rapid response if significant air entry occurs.
Anatomic variation of the vertebral artery: a case involving a persistent first intersegmental artery at C1-C2.

Department of Otolaryngology, Shenzhen Longgang Otolaryngology hospital& Shenzhen Otolaryngology Research Institute, No. 3004, Longgang Avenue, Shen Zhen City, 518172, Guangdong Province, China.
Background: We observed a rare anatomical variation of a persistent first intersegmental vertebral artery in the C1-C2 region in an elderly Chinese male cadaver at Changzhi Medical College. In this case, the vertebral artery, rather than passing through the transverse foramen of the atlas, exits the transverse foramen of C2 and enters the spinal canal at the lower portion of the C1 posterior arch. The original transverse foramen of C1 was filled with connective tissue.

Purpose: To describe a case of an anomalous posterosuperior course of the V3 segment of the right vertebral artery (VA) that penetrated the occipital bone (wall of the jugular foramen).
Methods: A 33-year-old healthy woman underwent cranial magnetic resonance (MR) imaging and MR angiography from the upper cervical to the intracranial region using a 3-Tesla scanner to screen for asymptomatic brain lesions, including cerebrovascular diseases.
Results: MR angiography showed no pathological arterial lesions such as aneurysms; however, there was an anomalous posterosuperior course of the V3 segment of the right VA.
