Intravenous leiomyomatosis (IVL) is defined as a benign smooth muscle tumor, growing within systemic veins. IVL with intracaval and intracardiac extension has rarely been reported in radiological and oncological journals. The present study describes 2 cases of IVL extending from the inferior vena cava to the right atrium and ventricle, and discusses the imaging findings and differential diagnos...

Intravascular large B-cell lymphoma (IVL) is a rare type of extranodal diffuse large B-cell lymphoma (DLBCL), which often infiltrates the central nervous system (CNS) during the clinical course. Cerebral hemorrhage in patients with CNS lymphoma at presentation is rare. Herein, we describe a case of secondary CNS lymphoma with intratumoral hemorrhage, which was suggested as IVL from autopsy find...

Introduction: Au Gabon, le dépistage des lésions précancéreuses et cancéreuses du col de l'utérus n'est pas systématique. La vulgarisation de ce dépistage suppose l'utilisation d'un test efficace et adapté aux réalités locales. Méthodes: L'objectif de cette étude était de comparer les performances du frottis cervico-vaginal (FCV) conventionnel et de l'inspection visuelle à l'acide acétique (IVA...

Intravascular lymphomatosis (IVL) is a rare angiotrophic large cell lymphoma producing vascular occlusion of arterioles, capillaries, and venules. Antigenic phenotyping shows that these lymphomas are mostly of B cell type, and less commonly T cell or Ki-1 lymphomas. The central nervous system and skin are the two most commonly affected organs; patients usually present with progressive encephalo...

BACKGROUND Intravascular lymphoma (IVL) is an uncommon disease characterized by atypical lymphoid cells growing inside the lumina of small vessels. The diversity of clinical presentation due to possible involvement of multiple organs often complicates its diagnosis. CASE REPORT Here, we report on a case of IVL with rapidly progressive dementia and Coombs-negative hemolytic anemia. Interesting...

Intravenous leiomyomatosis (IVL) is a rare benign tumor of the uterus mesoderm, which can spread via the vein, from the micro-vein to the inferior vena cava, and even to the right atrium. IVL was first described this disease in 1896 and the first presented case of IVL with right atrium extension in the autopsy was described in 1907. On rare occasions, the tumors may extend into the regional and...

Intravascular lymphoma (IVL) is a rare entity of extranodal large cell lymphoma. Most cases of IVL are B-cell phenotype, with a few cases of T-cell or NK-cell origin. To our knowledge, only 5 cases of intravascular cytotoxic T-cell lymphoma with sufficient phenotype studies have been reported so far. Here, a case of intravascular cytotoxic T-cell lymphoma initially occurred in epididymis in a 6...

PURPOSE Intravascular lymphomatosis (IVL) is rare and usually goes undiagnosed until the time of autopsy because of its protean neurological manifestations. CASE REPORT In this report, we describe two women who developed rapidly recurrent strokes within one to two months. In both cases, brain magnetic resonance imaging showed progression of bilateral cerebral infarcts, and histopathology from...

Although Particle Swarm Optimization (PSO) has demonstrated competitive performance in solving global optimization problems, it exhibits some limitations when dealing with optimization problems with high dimensionality and complex landscape. In this paper, we integrate some problem-oriented knowledge into the design of a certain PSO variant. The resulting novel PSO algorithm with an inner varia...

Calcium plate fracture is a mechanism of Intravascular Lithotripsy (IVL). Using IVUS, POBA studies from the early 1990’s demonstrated separation between calcium – noncalcium junction (i.e., “debonding”). Importance debonding has not been evaluated in modern era IVL. We hypothesize that significantly contributes to improved compliance IVL treated calcified vessels and evaluate contribution intim...
