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 Intravesical bacillus Calmette-Guerin (BCG) is used in the treatment and prophylaxis of carcinoma in situ of the urinary bladder and for the prophylaxis of primary or recurrent stage Ta and T1 papillary tumors following transurethral resection. Significant systemic complications are rare but have been reported. CASE REPORT We describe this case of Mycobacterium bovis psoas abscess and worsening abdominal aortic aneurysm following BCG therapy for bladder cancer. A 76-year-old male presented with a fever of a few days...

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...

We report a 31 year old woman presented with three months history of large untreated parapharyngeal abscess and bleeding from the mouth. On evaluation chest CT scan identified the abscess extending down to the superior mediastinum and multiple small lung abscesses. Echocardiography showed tricuspid valve insufficiency. Patient was brought to the operating room (OR) and intra-operatively it was found that she had multiple large mycotic pseudoaneurysms of the internal jugular vein and right brachiocephalic veins...

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...

Treatment of mycotic aortic aneurysms (MAA) composes a particularly difficult challenge. Open repair (OR) has been considered the gold standard, despite lack of evidence supporting its superiority compared with the emerging alternative endovascular aortic repair (EVAR). This review discusses the pros and cons of EVAR for MAAs by dissecting the three largest publications on MAAs, and concludes that there has been a paradigm shift in treatment of MAAs for the benefit of EVAR.

INTRODUCTION: Mycotic aneurysms are a serious complication of infective endocarditis with increased risk of intracranial hemorrhage. Patients undergoing open heart surgery for valve repair or replacement are exposed to anticoagulants, increasing the risk of aneurysm bleeding. These patients may require endovascular or surgical aneurysm treatment prior to heart surgery, but data on this approach are scarce. METHODS: Retrospective review of consecutive patients with infectious endocarditis and mycotic aneurysms treated endovascularly with Trufill n-butyl cyanoacrylate (n-BCA) at the Cleveland Clinic between January 2013 and December 2015...

Infected or mycotic aneurysms (MA) of the aorta and adjacent arteries are rare and difficult to treat. We report a unique case of a Salmonella serotype enteritidis-induced rapidly expanding aortic and iliac pseudoaneurysm during pre-operative work-up. Based on the presented case, we postulate that the agressive nature of Salmonella Enteritidis MA should not be underestimated. If postponed intervention is chosen and the patient is managed conservatively with antibiotic therapy to create a window of definitive diagnosis one should consider close follow-up imaging to observe progression of the pseudo aneurysm...

In the words of Sir William Osler: "There is no disease more conducive to clinical humility than aneurysms of the aorta". Here, we describe a case of a primary fistulous tract between a pseudoaneurysm sac and a portion of the mid thoracic esophagus leading to massive extravasation of blood causing hemorrhagic shock in a 71-year-old female.

We report the case of a patient with ICA mycotic pseudo-aneurysm secondary to Lemierre's syndrome, urgently treated. A 75 years old man presented to E.R. with a left swelling lesion of the neck and complaining left visions lost since that morning, fever, hypotension and dyspnoea. Since fifteen days before developing symptoms, he had sore throat and odynophagia treated with a broad coverage of antibiotic therapy for presumed streptococcal pharyngitis. Preoperative CTA images revealed a circular lesion, involving the common carotid artery, carotid bulb, and the proximal part of the internal and external carotid arteries...

18F-FDG-PET may be useful to diagnose complications of endocarditis in difficult cases. We report the case of a young patient who had endocarditis and a painful leg. FDG PET/CT showed hypermetabolism in the leg and duplex ultrasound suggested an inflammatory aneurysm at the site of the hypermetabolism. The combination of FDG-PET/CT and duplex ultrasound is useful to diagnose mycotic aneurysm in the setting of bacterial endocarditis.

Spontaneous subarachnoid hemorrhage (SAH) as the presenting feature of infective endocarditis (IE) is rare. It has classically been described in association with the rupture of intracranial mycotic aneurysms (ICMA). Here we describe a very rare case of non-aneurysmal spontaneous SAH in a patient with IE. The patient originally presented with a headache and low-grade fever. Neuroimaging including computed tomography (CT) and magnetic resonance imaging (MRI) of the head revealed SAH. She was eventually diagnosed with streptococcus gallolyticus (formerly streptococcus bovis) IE...

A 74-year-old man with a history of mitral valve repair was referred to our hospital with fever and diagnosed with mitral valve endocarditis involving occlusion of the superior mesenteric artery. Bacterial cultures showed Staphylococcus lugdunensis. Despite antibiotic therapy, orthopnea ensued due to valve destruction. Emergency mitral valve replacement was performed. Computed tomography on postoperative day 10 revealed a rapidly expanding mycotic aneurysm of the superior mesenteric artery. Aneurysmectomy was undertaken...
