Complex coronary artery disease with severe calcification can be challenging to treat, a higher risk of procedural complications and major adverse cardiac events. Intravascular lithotripsy (IVL) is pioneering technology for the treatment critically calcified coronaries. IVL utilizing localized pulsatile sonic pressure waves at low provides novel approach lesion preparation severely plaques. The...

IVL is characterized by a propensity for intravascular tumor cell proliferation. Premortem diagnosis of IVL is difficult because of its nonspecific clinical, laboratory, and imaging manifestations. This study examined cerebral MR imaging patterns of IVL and their changes with and without chemotherapy. Nine of 11 patients studied presented with abnormal findings. We define 5 patterns of abnormal...

Intravascular lymphoma (IVL) is a rare disease characterized by the proliferation of lymphoma cells in the lumen of the small blood vessels. Although early diagnosis of IVL is important to prolong survival of the patients, its atypical symptoms and clinical course often delay its diagnosis. More than half of the patients are diagnosed at autopsy. We report a 68-year-old man who presented with t...

BACKGROUND Intravascular lymphomatosis (IVL) is an uncommon systemic disease characterized by occlusion of small vessels by malignant lymphomatous cells. Central nervous system involvement usually presents as subacute encephalopathy, dementia, seizures, or multifocal cerebrovascular events. OBJECTIVE To increase awareness about IVL, an uncommon cause of neurological disease. DESIGN This is ...

A 65-year-old woman was admitted to our hospital for the evaluation of rapidly progressive renal dysfunction with serum creatinine of 2.7 mg/dl and urinary protein of 1.5 g daily. C-reactive protein (CRP) was 0.1 mg/dl. Kidney-limited intravascular large B-cell lymphoma (IVL) localized to the glomerular capillaries was diagnosed because the intraglomerular cells were positive for CD20 and CD79a...

Objective Intravenous leiomyomatosis (IVL) is a rare and aggressive tumor type that has the potential to extend into inferior vena cava (IVC) susceptible be misdiagnosed neglected. Despite its clinical significance, there paucity of research focused on specific manifestations IVL ultrasonography. Therefore, this study aims systematically analyze ultrasound features augment diagnostic accuracy. ...

Vestibular damage can induce locomotor abnormalities in both animals and humans. Rodents with bilateral vestibular loss showed vestibular deficits syndrome such as circling, opisthotonus as well as locomotor and exploratory hyperactivity. Previous studies have investigated the changes in the dopamine system after vestibular loss, but the results are inconsistent and inconclusive. Numerous evide...

The aim of this study is to investigate the imaging features of intravascular leiomyoma (IVL) involving the heart and the imaging techniques in the diagnosis of this disease. The imaging features of contrast-enhanced computed tomography (CT), the clinical data and the pathological data of a case of IVL involving the right atrium were retrospectively analyzed and the literatures were reviewed. A...

This report documents a case of intravascular lymphoma (IVL) with increased regional cerebral blood flow (rCBF) disclosed at I-123 IMP single-photon emission CT (IMP-SPECT). A 73-year-old woman with IVL had high rCBF disclosed by IMP-SPECT before chemotherapy; rCBF was normal after one course of CHOP (cyclophophamide, vincristine, doxorubicin, and prednisone) chemotherapy. During her clinical c...
