“…An der Arteria vertebralis ist besonders häufig der Abschnitt V3 oberhalb und unterhalb des ersten Halswirbels (C1) betroffen (▶ Abb. 2B) [9], die Segmenteinteilung der Arteria vertebralis ist in ▶ Abb. 3 und der Infobox "Segmente der Arteria vertebralis" dokumentiert.…”

“…In the vertebral artery, section V3 above and below the first cervical vertebra (C1) is particularly frequently affected (▶ Fig. 2B) [9]; the segmental division of the vertebral artery is documented in ▶ Fig. 3 and the "Segments of the vertebral artery" information box.…”

“…Zwei Formen der Immunvaskulitis können sich an den großen extrakraniellen Gefäßen manifestieren und mit Ultraschall nachgewiesen werden: Takayasu-Arteriitis und Riesenzellarteriitis. In den typischen Fällen zeigt das Gefäß eine lange, homogen echoarme, konzentrische Wandverdickung, die zu einer Lumeneinengung führt [9]. Das Gefäß ist auch geringgradig nach außen erweitert.…”

Section: Großgefäß-vaskulitisunclassified

“…Two forms of immune vasculitis may manifest in the large extracranial vessels and be detected by ultrasound: Takayasu arteritis and giant cell arteritis. In typical cases, the vessel shows a long, homogeneously hypoechoic, concentric wall thickening leading to lumen narrowing [9]. The Allerdings handelt es sich dann ebenso wie bei der Fensterung um einen stabilen Zustand, der keine Behandlung mit Antikoagulanzien oder Thrombozyten-Funktionshemmern wie bei einer akuten Dissektion erfordert.…”

Spontaneous dissection of brain-supplying cervical arteries, which also includes findings after minor injuries, is one of the main causes of ischaemic strokes in young adults. Strokes due to dissection are usually due to arterio-arterial embolism. They are rarely the first symptom of dissection because an intraluminal thrombus must first develop. Therefore, early diagnosis of dissection can contribute to stroke prevention – through immediate therapy with anticoagulants or antiplatelet drugs. This article describes the diagnostic criteria and typical findings of spontaneous dissection, in which no dissecting membrane is to be expected as in aortic dissection. Traumatic dissections following blunt or penetrating injuries also present with different findings. Examiners should be aware of possible differential diagnoses whose ultrasound image may mimic a dissection. A frequently occurring but avoidable cause of misdiagnosis is idiopathic carotidynia. Ultrasound also enables differentiation between dissection and vasculitis or carotid web and detection of normal variants such as fenestration of the vertebral artery. Further possibilities for misdiagnosis may arise in the presence of a variant of the ascending pharyngeal artery or in extracranial vasospasm. The different imaging techniques for the detection of a dissection are complementary, as false-negative findings occur with all techniques; no method serves as the gold standard. In any case, ultrasound can make an important contribution to the detection of a dissection, and it is worth knowing the diagnostic criteria.

The second part of this continuing medical education article focuses on sonographic assessment of the salivary glands, cervical paraganglioma, angioma, esophagus, extra cranial blood vessels and the temporomandibular joint. The currently available minimally invasive therapeutic options (e. g. sialendoscopy, lithotripsy, therapeutic duct lavage and extracapsular dissection) for salivary gland disease presuppose a precise imaging modality. Modern ultrasound is able to meet this challenge, making additional imaging a rare necessity. Regions of the neck with a difficult topography (esophagus and hypopharynx) can often be successfully portrayed sonographically. Furthermore, ultrasound enables functional evaluation of swallowing in the cervical parts of the esophagus in dysphagia patients. In addition to the branchial cleft anomalies and lymph nodes discussed in part 1, paraganglioma, angiomatosis and neurogenic tumors are important differential diagnoses of solid lesions of the neck. Finally, venous and arterial alterations of the extracranial vessels of the neck relevant to clinical routine are depicted, as are pathological conditions of the temporomandibular joint relevant to the otorhinolaryngologist.
