Fatal Intracranial Hemorrhage after Intravenous Thrombolytic Therapy for Acute Ischemic Stroke Associated with Cancer-related Nonbacterial Thrombotic Endocarditis
Nonbacterial thrombotic endocarditis (NBTE) is associated with hypercoagulability in patients with inflammatory states such as cancer and autoimmune diseases. Cardiac vegetations caused by NBTE often lead to life-threatening systemic thromboembolism that most frequently affects the brain, spleen, and kidneys. A 54-year-old woman diagnosed with ovarian cancer suddenly developed back pain and left hemiparesis. Although intravenous alteplase (rt-PA) therapy was administered to treat hyperacute ischemic infarction detected by magnetic resonance imaging, intracranial hemorrhage occurred in the left hemisphere several hours late...

Low NIHSS score large vessel occlusion caused by infective endocarditis treated with thrombectomy
A 24-year-old woman had undergone dental treatment 3 weeks before and had a mild fever for a week. She presented to the emergency department with the chief complaint of weakness in the right upper limb after waking up. She had mild paralysis of the right upper limb (National Institutes of Health Stroke Scale [NIHSS] score 1). Head magnetic resonance imaging (MRI) showed scattered infarcts in the left frontal and parietal lobes and left internal cerebral artery (ICA) occlusion (Fig. 1A, B). Cerebral angiography showed that the left ICA was occluded immediately after its origin (Fig.

Determinants of Cerebral Lesions in Endocarditis on Systematic Cerebral Magnetic Resonance Imaging: A Prospective Study Clinical Sciences
Conclusions— Systematic cerebral MRI frequently detects ischemic lesions and microbleeds during acute IE. The high sensitivity of MRI shows that each millimeter increase in vegetation length is associated with a 10% increase in the rate of ischemic lesions. Conversely, microbleeds are associated only with prosthetic IE in this study. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00144885.

Prediction of early postoperative cerebral hemorrhage in infective endocarditis patients using magnetic resonance imaging
Conclusion The combination of T2*-weighted MRI and DWI may be useful to evaluate the risk of IE patients developing major postoperative cerebral bleeding.

Clinical Associations of Cerebral Microbleeds on Magnetic Resonance Neuroimaging
Susceptibility-weighted and gradient-recalled echo T2* magnetic resonance imaging have enabled the detection of very small foci of blood within the brain, which have been termed “cerebral microbleeds.” These petechial intraparenchymal hemorrhages have begun to emerge as diagnostically and prognostically useful markers in a variety of disease states. Severe hypertension and cerebral amyloid angiopathy are perhaps the best established microhemorrhagic conditions from neuroimaging literature; however, many others are also recognized including cerebral autosomal dominant arteriopathy, subcortical infarcts, and leukoencepha...

Drainage of cerebral abscesses prior to valve replacement in stable patients with acute left-sided infective endocarditis.
We present a case of a 46 year old male patient who presented to our clinic with mitral valve IE caused by coagulase negative staphylococcus. Although under correct antibiotic treatment, he continued to be feverish and started to present unspecific neurological symptoms (amnesia, confusion, asthenia and general malaise). The cerebral magnetic resonance imaging (MRI) revealed multiple cerebral abscesses. Because the patient was hemodynamically stable we decided to address the cerebral abscess first and the cardiac lesion second. The patient made a full recovery after undergoing antibiotic treatment and surgical procedures o...

Neurologic outcomes of preoperative acute silent cerebral infarction in patients with cardiac surgery.
CONCLUSION: Patients with preoperative ASCI showed excellent postoperative neurologic outcomes. Preoperative ASCI was not a risk factor for postoperative neurologic deterioration. PMID: 25551071 [PubMed]

Non-Bacterial Thrombotic Endocarditis in a Patient with Rheumatoid Arthritis.
Authors: Choi JH, Park JE, Kim JY, Kang T Abstract Rheumatoid arthritis (RA) is frequently associated with various extra-joint complications. Although rare, thromboembolic complications are associated with high morbidity and mortality. We experienced a very rare case of nonbacterial thrombotic endocarditis (NBTE) and subsequent embolic stroke in a patient with RA. A 72-year-old male with a 15-year history of RA suddenly developed neurologic symptoms of vomiting and dizziness. Brain magnetic resonance imaging revealed recently developed multiple cerebellar and cerebral lacunar infarctions. Echocardiography showed a ...

Cerebral Infarcts by Nonbacterial Thrombotic Endocarditis Associated with Adenomyosis: A Case Report
We report a case of multiple embolic cerebral infarcts associated with nonbacterial thrombotic endocarditis (NBTE) in a patient with adenomyosis. The patient presented with dysarthria, left perioral sensory change, and left-hand weakness. Magnetic resonance imaging revealed multiple vascular territory infarctions involving the bilateral cerebellum and the right precentral gyrus. Magnetic resonance angiography was normal. d-Dimer, carbohydrate antigen (CA) 19-9, and CA125 levels were elevated. Abdominal and pelvic computed tomography with iodine contrast enhancement revealed a huge adenomyosis with left ovarian cyst.

Combined brain/heart magnetic resonance imaging in systemic lupus erythematosus.
Authors: Mavrogeni S, Koutsogeorgopoulou L, Dimitroulas T, Markousis-Mavrogenis G, Boki K, Katsifis G, Vartela V, Kallenberg CG, Kolovou G, Kitas G Abstract Cardiovascular disease (CVD) in systemic lupus erythematosus (SLE) and neuropsychiatric SLE (NPSLE) have an estimated prevalence of 50% and 40% respectively and both constitute major causes death among SLE patients. In this review, we propose a combined brain/heart magnetic resonance imaging (MRI) for SLE risk stratification. The pathophysiologic background of NPSLE includes microangiopathy, macroscopic infarcts and accelerated atherosclerosis. Classic brain MR...

Nonbacterial Thrombotic Endocarditis Related to Adenocarcinoma of the Uterine Cervix
We report a 66-year-old female patient who presented with acute onset of visual loss with relative afferent pupillary defect, hemineglect, hemihypesthesia, and apraxia. Magnetic resonance imaging of the brain demonstrated different stages of ischemic stroke in different vascular territories, suggesting cardiogenic embolism. Past history was significant for advanced-stage adenocarcinoma of the uterine cervix under chemoradiation treatment. On echocardiogram, vegetation at the aortic valve was observed. With the absence of evidence of infectious endocarditis, diagnosis of nonbacterial thrombotic endocarditis was made, and th...
