PURPOSE OF REVIEW: The purpose of this paper is to provide recent insights in management of neurologic complications of left-sided infective endocarditis (IE). RECENT FINDINGS: Cerebral lesions observed in IE patients are thought to involve synergistic pathophysiological mechanisms including thromboembolism, sepsis, meningitis, and small-vessel cerebral vasculitis. Brain MRI represents a major tool for the detection of asymptomatic events occurring in the majority of patients...

Mycotic aneurysm after bacteremia is a rare diagnosis in children and adolescents. We report the case of a previously healthy adolescent who presented with chest pain and fever and who developed a mycotic aneurysm of the aorta after contracting community-acquired, methicillin-resistant Staphylococcus aureus. Early recognition of widening of the patient's superior mediastinum, noted during a comparison of the patient's initial and follow-up chest radiographs, prompted computed tomographic angiography of the chest and led to a timely diagnosis, rapid surgical intervention, and a good clinical outcome...

PURPOSE: Artificial neural networks (ANN) are increasingly applied to complex medical problem solving algorithms because their outcome prediction performance is superior to existing multiple regression models. ANN can successfully identify symptomatic cerebral vasospasm (SCV) in adults presenting after aneurysmal subarachnoid hemorrhage (aSAH). Although SCV is unusual in children with aSAH, the clinical consequences are severe. Consequently, reliable tools to predict patients at greatest risk for SCV may have significant value...

OBJECTIVE/BACKGROUND: Endovascular repair (EVAR) of mycotic aortic aneurysm (MAA) has become an alternative treatment for high risk patients. The aim of this study was to evaluate long-term survival and outcomes. METHODS: Retrospective analysis of 40 consecutive patients with MAAs undergoing EVAR and subsequent intravenous antibiotic treatment between September 2009 and April 2015. Follow-up was truncated on 30 April 2015. Uni- and multivariate logistic regression were used to assess risk factors of adverse outcomes...

BACKGROUND: Diffuse intracranial aneurysmal vasculopathy is a rare condition, previously described in patients with human immunodeficiency virus (HIV) infection. IgG4 related disease (IgG4-RD) is a recognized inflammatory disease of systemic organs, leading to fibrosis of connective tissues. It has also been linked to inflammatory dilating aortic aneurysms, coronary vascular disease, hypophysitis, orbital pseudotumor and pachymeningitis. It has not yet been described as a cause of diffuse intracranial dilating vasculopathy...

BACKGROUND: Mycotic aneurysm is a rare potentially life-threatening complication of infective endocarditis (IE). Little data is available on the management and outcomes of ruptured mycotic aneurysms with large intracerebral hematoma. Few cases have been described on the management of mycotic aneurysm in the presence of life-threatening hematoma and mass effect. CASE DESCRIPTION: We are presenting two cases of ruptured mycotic aneurysm with intracerebral hematoma and impending brain herniation...

Fungal infections of the central nervous system (CNS) frequently occur in immunosuppressed patients. Here, we describe the case of an immunocompetent 64-year-old man who presented with diplopia, right-sided hemiparesis, and a mild headache after cleaning and replacing nesting boxes of wild birds during the preceding months. Lumbar puncture revealed pleocytosis, elevated protein, and lactate levels in the cerebrospinal fluid (CSF). Initial imaging showed ischemia in the left thalamus and an enlargement of the sellar region...

Firstly described in the 19th century by Sir William Osler, the mycotic aneurysm (MA) is a rare entity characterized by an abnormal arterial dilation, which is potentially fatal, and is associated with the infection of the vascular wall. Elderly patients are mostly involved, especially when risk factors like chronic diseases, immunosuppression, neoplasia, and arterial manipulation are associated. The authors report the case of a young male patient diagnosed with an aortic aneurysm of infectious origin in the presence of repeated negative blood cultures...

After an infectious complication caused by bacillus Calmette-Guérin (BCG), consider a dose reduction. Treatment of a mycotic aneurysm with an endostent seems safe; however, continuation of BCG after mycotic aneurysm treatment is not advised.

To prevent life-threatening aortic ruptures, it is important that primary care physicians and urologists are aware of the symptoms of a mycotic abdominal aortic aneurysm, even several months or years after bacillus Calmette-Guérin therapy.

BACKGROUND: Intracranial mycotic aneurysm (IMA) is a rare neurovascular disease and a well-known complication following infective endocarditis. IMAs potentially carry a high mortality risk due to intracranial hemorrhage. Therefore, initial treatment is crucial for IMA patients, but an optimal treatment strategy remains unknown. Herein, we report two cases of IMA patients treated with the current usual modalities, and we provide a comprehensive literature review to propose an optimal initial treatment strategy for IMAs...

A 16-year-old girl was admitted with a 7-month history of recurrent fever, weight loss of 5 kg, and general poor health status. Blood culture was positive with Streptococcus viridans. Transthoracic echocardiography established an aneurysm of the root of left subclavian artery, associated with an aortic coarctation just before the origin of the left subclavian artery with a velocity of 4.8 cm/s. Three-dimensional echocardiography demonstrated the entire inner structure of the aneurysm. Computed tomography reconstruction confirmed the presence of aortic coarctation and mycotic aneurysm, it also revealed an aberrant right subclavian artery...

An 83 year-old-man with left atrial appendage occluder (LAAO) developed Pseudomonas Aeruginosa (PA) infective endocarditis. MRI at day 3 of onset showed distal small infarcts in both middle cerebral arteries and left postero-inferior cerebellar artery territories. MRI at day 6 revealed two sites of convexity subarachnoid hemorrhage (cSAH). MRA and CTA failed to reveal a Mycotic aneurysm. The radiologic findings favor the assumption of necrosis of distal branches of mca or of pial arteries wall. This case present three unusual features: the presence of localized cSAH after initiation of antibiotherapy without mycotic aneurysm being individualized; the late occurrence of infective endocarditis after LAAO implantation; the very rare occurrence of PA in prosthetic infections...

Stroke is the fifth leading cause of death and is responsible for approximately nine percent of all deaths worldwide. Cases of Streptococcus mutans (S. mutans)-induced intracerebral hemorrhage as a result of bloodstream infections have seldom been reported. New reports show that bacteria with specific collagen binding proteins (CBPs), such as the Cnm type produced by S. mutans, may inhibit platelet aggregation and cause bleeding. In this article, we report on a 62-year-old man with a recent history of left frontal intracerebral hemorrhage (ICH) who presented to the emergency department after a fall due to suspected seizure while in rehabilitation...

BACKGROUND: There is no international consensus regarding the optimum management of infected aortae (mycotic aneurysms, infected aortic grafts). Neoaortoiliac reconstruction has advantages over extra-anatomical bypass grafting; however, the use of autologous vein is associated with venous hypertension and compartment syndrome, alternatively cadaveric homografts are associated with high rates of perianastomotic hemorrhage, limb occlusion, and pseudoaneurysm. Arterial repair using xenoprosthetic patches is associated with lower infection rates compared to the use of prosthetic material...
