Spine vascular lesions like brain include spinal cord stroke, malformation such as venous or angioma, cavernous malformation, arteriovenous fistula. Embryogenesis of is the basic principle to understand spine. This study aims report serial cases with review lesions. MR angiography techniques contrast injection may reflect direction flow epidural veins describe site arterial feeders. Serpiginous...

Vascular lesions of the head and neck include vascular neoplasms, vascular malformations, and hypervascular lesions, derived from nonvascular soft-tissue elements. We retrospectively evaluated magnetic resonance imaging and computed tomography images of vascular lesions located in the head and neck. Twelve patients (seven males, five females) aged 1-68 years (mean age, 35.25 years) were include...

background: linear endoscopic ultrasonography (eus) is a proven modality for the diagnosis and treatment of different gastrointestinal lesions. the aim of this study was to describe the role of eus-fna in the evaluation of pancreatic and submucosal lesions. materials and methods: over a 1-year period, in a prospective descriptive study, patients referred to naft hospital, underwent linear eus. ...

During the past few decades, there have been significant advances in the understanding of spinal vascular lesions, mainly because of the evolution of imaging technology and selective spinal angiography techniques. In this article, we discuss the classification, pathophysiology, and clinical manifestations of spinal vascular lesions other than DAVFs and provide a review of the endovascular appro...

Intravascular papillary endothelial hyperplasia (IPEH) is an uncommon benign vascular disease characterized by endothelial cell proliferation and papillary formation within the lumen of blood vessels arising from an organizing thrombus. The occurrence of this uncommon lesion is about 2% of all vascular tumors. IPEH mostly occurs in the 5th decade of life, and there is no gender or age predilect...

F acial vascular malformations can cause dental emergencies that result in fatal or life-threatening and disfiguring situations. 14 Dentists must be aware of the clinical manifestations of these lesions in order to prevent iatrogenically related accidents and to minimize potential spontaneous crises for the patient. Effective treatment depends on the type and location of vascular lesion. Litera...

BACKGROUND This article reviews the anatomy, connections, and functions of the thalamic nuclei, their vascular supply, and the clinical syndromes that result from thalamic infarction. SUMMARY OF REVIEW Thalamic nuclei are composed of 5 major functional classes: reticular and intralaminar nuclei that subserve arousal and nociception; sensory nuclei in all major domains; effector nuclei concern...

BACKGROUND Kawasaki disease (KD) is the most common systemic vasculitis of unknown etiology in children, and can cause the life-threatening complication of coronary artery aneurysm. Although a novel treatment strategy for patients with KD-caused vascular lesions is eagerly awaited, their molecular pathogenesis remains largely unknown. c-Jun N-terminal kinase (JNK) is a signaling molecule known ...
