We report a very rare case of mitral valve dissection and aortic-left ventricular tunnel caused by possible autoimmune vasculitis. We suspected Behcet's disease in this patient. There was no obvious clinical evidence of infective endocarditis. Echocardiography is the diagnostic tool of choice to recognize valvular dysfunction, related pathology, and possible complications. The patient may require immunosuppressive therapy due to the high likelihood of recurrence in the perioperation period.

We report the clinical details, imaging findings, and management for a 39-year-old female presenting with recurrent episodes of pain in abdomen due to systemic lupus erythematous vasculitis associated with spontaneous isolated inferior mesenteric dissection. Spontaneous mesenteric artery dissection is an uncommon cause of mesenteric ischemia. Symptomatic spontaneous isolated inferior mesenteric artery (IMA) dissection is a rare condition, and its association with systemic lupus erythematosus is not previously described in the English literature...

INTRODUCTION: Takayasu aortitis is a well known yet rare form of large vessel vasculitis. Also known as pulseless disease, occlusive thromboaortopathy, and Martorell syndrome, is a chronic inflammatory aortitis. Vessel inflammation leads to wall thickening, fibrosis, stenosis, and thrombus formation. METHODS: A 64-year-old woman was referred to emergency for lack of pulse in the upper and lower limbs and changes in heart rate. AngioRMN revealed dissection of the ascending aorta while in PET, intense uptake of FDG-F18 involving ascending, crossa, descending thoracic and abdominal segments of the aorta, was evident urgent surgical correction occurred...

OBJECTIVE: The objective of this video article is to provide education about the similarities and differences between vasculitis and rare, acute aortic pathologic findings so that an appropriate diagnosis can be made in a timely manner, especially for patients with life-threatening aortic pathologic findings. CONCLUSION: Although they are rare, acute aortic pathologic findings, such as aortic dissection and intramural hematoma, can have radiographic characteristics similar to those of vasculitis, which can make it challenging to discern between these vastly different diagnoses without the use of properly timed imaging studies...

Cocaine, a natural alkaloid derived from the coca plant, is one of the most commonly used illicit drugs. Cocaine abuse causes systemic adverse effects like stroke, myocardic infarction, arterial dissection, vascular thrombosis and rhabdomyolysis. Cocaine use is, also, associated with renal complications such as acute kidney injury, vasculitis, acute interstitial nephritis, chronic kidney disease, malignant hypertension with thrombotic microangiopathy. Acute kidney injury may or may be not associated to rhabdomyolysis...

Vessel wall magnetic resonance imaging (VW-MRI) is a modern imaging technique with expanding applications in the characterization of intracranial vessel wall pathology. VW-MRI provides added diagnostic capacity compared with conventional luminal imaging methods. This review explores the principles of VW-MRI and typical imaging features of various vessel wall pathologies, such as atherosclerosis, dissection, and vasculitis. Radiologists should be familiar with this important imaging technique, given its increasing use and future relevance to everyday practice...

Polymyalgia rheumatica (PMR) represents the most common inflammatory rheumatic disease of the elderly. It is characterized by synovitis of proximal joints and extra-articular synovial structures, along with chronic high-grade systemic inflammation. PMR is closely related to giant cell arteritis (GCA), a large-vessel vasculitis that involves the major branches of the aorta, particularly the extracranial branches of carotid artery including temporal arteries. It is currently believed that PMR and GCA may represent different manifestations of the same disease process...

INTRODUCTION: Segmental arterial mediolysis (SAM) is a rare nonatherosclerotic, noninflammatory vasculopathy causing arterial wall necrosis that leads to strictures, dissections, and aneurysms, particularly in medium-sized abdominal arteries. Awareness of SAM is important because, unlike vasculitides, immunosuppressive treatment may worsen the disease process. CASE: A 58-year-old man with multiple medical comorbidities presented with acute epigastric pain and a right incarcerated inguinal hernia that was interpreted as showing bowel strangulation on computed tomography...

Intracranial vessel wall magnetic resonance (MR) imaging has gained much attention in the past decade and has become part of state-of-the-art MR imaging protocols to assist in diagnosing the cause of ischemic stroke. With intracranial vessel wall imaging, vessel wall characteristics have tentatively been described for atherosclerosis, vasculitis, dissections, Moyamoya disease, and aneurysms. With the increasing demand and subsequently increased use of intracranial vessel wall imaging in clinical practice, radiologists should be aware of the choices in imaging parameters and how they affect image quality, the clinical indications, methods of assessment, and limitations in the interpretation of these images...

The prospects for complement-targeted therapy in ANCA-associated vasculitis have been enhanced by a recent clinical trial in which C5a receptor 1 (C5aR1) inhibition safely replaced glucocorticoids in induction treatment. C5aR1 primes neutrophils for activation by anti-neutrophil cytoplasmic antibody (ANCA) and is therefore required in models of glomerulonephritis induced by anti-myeloperoxidase antibody. Although humoral and cellular autoimmunity play essential roles in ANCA-associated vasculitis, a role for C5aR1 in these responses has not been described...

Spontaneous coronary artery dissection (SCAD) is an emerging and rare cause of acute coronary syndrome and sudden cardiac death. While it was previously reported among young females with fibromuscular dysplasia, new literature indicates that this condition could occur in older populations. Polyarteritis nodosa (PAN) causes systemic necrotizing vasculitis which typically affects small to medium-sized muscular arteries and could affect the coronary arteries. A few case reports of PAN causing acute coronary artery disease have been reported in the literature...

Idiopathic carotidynia (IC) is a rare and poorly understood syndrome consisting of unilateral neck pain, tenderness, and increased pulsations over the affected carotid bifurcation. A growing body of evidence supports the hypothesis that IC is a distinct clinicopathologic entity with characteristic imaging features. We report the case of a 34-year-old Caucasian male presenting with intense unilateral neck pain in the emergency setting. Computed tomography and ultrasonography revealed fusiform eccentric thickening of the ipsilateral carotid bifurcation without vessel narrowing...

Over the last decades, the importance of inflammatory processes in pediatric stroke have become increasingly evident. Ischemia launches a cascade of events: activation and inhibition of inflammation by a large network of cytokines, adhesion and small molecules, protease, and chemokines. There are major differences in the neonatal brain compared to adult brain, but developmental trajectories of the process during childhood are not yet well known. In neonatal stroke ischemia is the leading pathophysiology, but infectious and inflammatory processes have a significant input into the course and degree of tissue damage...

The authors have analyzed the causes of ischemic stroke (IS) in more than 600 young patients examined in the cerebrovascular department of the Neurological Research Center (Moscow) during the period 2003-2016 years. It has been suggested that a wider use of high-resolution MRI and T1 weighted db-fs images as well as intracranial CTA will help to verify more often intracranial dissection and primary cerebral vasculitis that will result in a decrease of cryptogenic IS frequency.

BACKGROUND: So-called juvenile stroke, i.e., stroke in a person aged 18 to 55, affects approximately 30 000 persons per year in Germany and is thus an important cause of mortality and permanent morbidity. The spectrum of causes of stroke is broader in this age group than in older patients and is also differently distributed. METHODS: This review is based on pertinent publications retrieved by a selective search in PubMed and on current guideline recommendations...

RATIONALE: Medial medullary infarction accounts for less than 1% of brain infarctions, and medial medullary infarctions is very rarely caused by antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. PATIENT CONCERNS: We report the case of a 76-year-old man at low risk of arteriosclerosis who presented with disorders on the left side including gaze-evoked nystagmus, paralysis of the extremities, pyramidal signs, sensory disturbance, and dysesthesia. Brain magnetic resonance imaging also showed right medial medullary infarction...
