A variation in the course of the thoracic duct was found in the cervical portion of a male cadaver during routine dissection of the head and neck region for undergraduate students. The thoracic duct, while arching laterally above the clavicle, was coursing posterior to the vertebral vein but anterior to the vertebral artery; it normally passes anterior to both the vertebral vein and artery. To ...

A 35 year old man experienced severe transitory neck pain following a violent sneeze. This was followed by neurological symptoms and signs indicating a left sided upper cervical cord lesion. MRI showed an infarct at this site in the territory of the left posterior spinal artery. This discrete infarct was probably due to partial left vertebral artery dissection secondary to sneezing.

The Graduate School of Medicine at Chiba University is planning to introduce computed tomography (CT) images of donated cadavers to the gross anatomy laboratory. Here we describe an anomaly of the right subclavian artery that was detected by interpretation of CT images prior to dissection. The anomaly was verified to be the right subclavian artery, as the last branch of the aortic arch, by subs...

CONTEXT Cervical artery dissection (CAD) is a common cause of stroke in young adults. There is controversy over whether anticoagulation is superior to antiplatelet therapy in preventing stroke in patients with CAD, although meta-analyses to date have not shown any difference between the two treatments. EVIDENCE ACQUISITION We performed a PubMed search using each of the keywords: "Cervical art...

vertebral artery is the first branch of subclavian artery. it merges with the same artery of the opposite side to form basilar artery and becomes one of the important source of blood supply to the brain. variation in the origin of left vertebral artery was found in 65 year old female during magnetic resonance angiography of the neck vessels. it originated from aortic arch and was longer as comp...

our case was a 48-year-old man with cervical pain radiatingto the upper limbs. imaging showed an intradural tumor with extradural component encasing the vertebral artery.thetumor diagnosed asa neurinomaand had been removed surgically.the post operationmagnetic resonance imagingshowed that the tumor was completely removed andthe vertebral arterywas intact at theentire length.the goal of surgery ...

BACKGROUND AND PURPOSE We sought to determine the clinical and neuroradiological features of intracranial vertebrobasilar artery dissection. METHODS The clinical features and MR findings of 31 patients (20 men and 11 women) with intracranial vertebrobasilar artery dissections confirmed by vertebral angiography were analyzed retrospectively. The vertebral angiography revealed the double lumen ...

The equipment and techniques associated with magnetic resonance imaging (MRI) have rapidly evolved. The development of 3.0 Tesla MRI has enabled high-resolution imaging of the intracranial vessel wall. High-resolution MRI (HRMRI) can yield excellent visualization of both the arterial wall and lumen, thus facilitating the detection of the primary and secondary features of intracranial arterial d...
