“…The CT angiography also showed a sensitivity ranging from 64% to 100%, and the specificity ranged from 82% to 95% . Both CT angiography and MR angiography can effectively visualize vertebral artery dissection; however, CT angiography can be performed rapidly, and it allows simple reconstruction of the dissection artery in an acute setting . Recently, it was shown that using the heavily T1‐weighted sequence on MRI could increase the reliability of detection of intramural hematoma compared with using the T1‐fat saturation method, which could improve the accuracy of vertebral artery dissection diagnosis .…”

Background This study aims to investigate the etiology and prognosis of spinal cord infarction (SCI). Methods Over a period of 16 years, we retrospectively analyzed 31 patients with SCI. Demographic features and symptom presentations were carefully documented. Etiology‐specific MRI features, such as the length and distribution of the lesions and owl’s eyes sign, were recorded and analyzed to determine their associations with the clinical signs/symptoms. Results In total, seven patients had aortic or vertebral artery dissections. We divided the patients with SCI into two groups: those with or without vessel dissection. Among SCI patients, the onset age was younger, and the proportion of patients with long‐segment lesions and posterior pattern involvement on axial view was higher in the group with dissection than in the group without dissection (all P < 0.05). The lesions were frequently located in the upper cervical or lower thoracic‐lumbar regions, and the lengths of the lesions were associated with 1‐month outcomes, suggesting that artery dissection may contribute to the longitudinal and posterior extension of SCI. In contrast, among patients without dissection, the range of longitudinal extensions of in spans of vertebral bodies was broader (range, 1–8). A higher proportion of patients had focal pain adjacent to the lesion (P = 0.05) and a poorer 1‐month outcome (P = 0.04) in the long‐segment lesion group than in the short‐segment lesion group. Conclusions A detailed history and the use of modern imaging tools may help clinicians search for vessel dissection and other etiologies, evaluate the spatial extension of lesions in SCI, and predict prognosis.

“…The second part (intraforaminal) is more or less fixed to the cervical vertebra and the third part (V3) is mobile with loops; both are highly susceptible to VAD 3 4 6. A variety of risk factors have been reported, including history of mechanical trauma, labor or delivery, recent infection, and rheumatoid diseases 3–5 7.…”

“…Risk factors for VAD are trauma, autoimmune diseases, infections, abrupt movements of the head, sporting activities, manual treatment of the neck, metabolic bone diseases, and congenital anomalies 2 3. Among these risk factors, traumatic atlantoaxial dislocation is assumed to be the most common cause while congenital anomaly of the atlantoaxial joint has been reported rarely.…”

We report an extremely rare case involving a posterior arch anomaly of the atlas, causing a vertebral artery dissection (VAD) induced posterior circulation stroke. A 16-year-old girl was admitted to hospital because of new onset dizziness. VAD related multiple infarction in the posterior circulation was revealed. The congenital posterior arch anomaly of the atlas, along with instability of the atlantoaxial joint, were discovered accidentally during follow-up. This is the first case of ischemic stroke related to atlantal posterior arch aplasia and atlantoaxial instability. Although rare, it reminds us that investigation of the craniovertebral junction should be considered when stroke occurs in young patients.

“…The classic triad is described as headache, Horner's syndrome and cerebral ischemia, including transient ischemic attacks (TIAs), which are present in about 30% of cases. 22 Vertebral arterial dissection may present with occipital headaches and symptoms suggestive of brainstem or posterior circulation infarction. 23 Vascular imaging is paramount in diagnosis, and although digital subtraction angiography is considered the gold standard, vascular imaging with CTA or MRA are both acceptable techniques in the emergency department setting.…”

Headache is seen in the emergency room (ER) on a daily basis and is a vague symptom, which can be a part of many different types of conditions and diseases. Although most people who come to the ER will have a benign headache, it is important to make sure that dangerous causes of headache are ruled out. There are a number of features that may alert someone to a secondary cause of headache. This article highlights two specific secondary headache syndromes, including carotid dissection and reversible cerebral vasoconstriction syndrome. It also broadly points out other possible causes of secondary headache. The last section focuses on a common primary headache that presents to the ER, migraine and its treatment.
