Abstract
BACKGROUND Mycotic aneurysms represent a rare type of intracranial aneurysm. Treatment options usually consist of coiling, clipping, or liquid embolization. Data regarding outcomes after flow diversion of mycotic aneurysms are sparse. OBJECTIVE To present a single-center case series regarding our experience with FD as definitive treatment for ruptured mycotic aneurysms initially treated with coil embolization. METHODS We retrospectively reviewed a prospectively maintained database of all cerebrovascular procedures performed at a single institution between 2017 and 2021 for cases that used FD for the management of intracranial mycotic aneurysms. Prospectively collected data included patient demographics, medical history, rupture status, aneurysm morphology, aneurysm location, and periprocedural complications. The main outcomes included neurological examination and radiographic occlusion rate on cerebral digital subtraction angiography. RESULTS Three patients with 4 ruptured mycotic aneurysms that were initially treated with coil embolization were identified that required retreatment. The aneurysms were located along the middle cerebral artery bifurcation (n = 2), posterior cerebral artery P1/2 junction (n = 1), and basilar artery apex (n = 1), which all demonstrated recurrence after initial coil embolization. Successful retreatment using flow diverting stents was performed in all 3 patients. At the last angiographic follow-up, all aneurysms demonstrated complete occlusion. No patients suffered new periprocedural complications or neurological deficits after FD. CONCLUSION Flow-diverting stents may be an effective treatment option for intracranial mycotic aneurysms that are refractory to previous endovascular coiling. Future studies are warranted to establish the associated long-term safety and clinical efficacy.

Abstract
PURPOSE Endovascular treatment (EVT) has become a major option in management of infectious intracranial aneurysms (IIAs) complicating infective endocarditis. We report a retrospective, single-center series of consecutive patients with IIAs treated by EVT. METHODS Patients were included from January 2009 to July 2020. IIAs were diagnosed on DSA. Each patient underwent a neurological assessment before and after EVT and was followed up by imaging within 15 days of EVT. Safety was assessed on the evolution of NIHSS score. A minor stroke was defined as a worsening of NIHSS < 4 points. Efficacy was defined as the absence of hemorrhagic event during cardiac surgery and the exclusion of the IIA on control imaging. RESULTS Sixty-two IIAs (30 ruptured) were diagnosed in 31 patients. Fifty-six IIAs were diagnosed on the first DSA and 6 on the early control exploration. EVT was achieved in 55 IIAs by parent artery occlusion with glue in 52 distal IIAs and coils in 3 proximal IIAs. IIAs were located in 90.9% of cases on a fourth-division branch of a cerebral artery. The neurological examination remained unchanged in 29 patients (93.5%), and 2 patients suffered minor stroke. EVT was performed before cardiac surgery in 20/22 patients. All treated IIAs were excluded on follow-up imaging. No hemorrhage was observed during cardiac surgery or in the aftermath. Seven (11.3%) unruptured IIAs were not embolized. CONCLUSION EVT of IIAs by occlusion of the parent artery is effective in preventing rupture and carries no significant neurological risk.

Abstract
Basilar artery dissections are rare events which present with subarachnoid hemorrhage (SAH), brain ischemia, and usually have a fatal outcome. Few case reports of mycotic dissections are published in literature. We report a case of a young male who underwent surgical treatment for post-traumatic CSF rhinorrhea. He presented 3 years later with signs of bacterial meningitis. During medical management with antibiotic therapy, he developed basilar artery aneurysm in a span of 2 days, had subarachnoid hemorrhage and deteriorated. CSF culture grew alpha hemolytic streptococci. Despite medical management, he developed brain stem infarcts and succumbed. This report highlights a rare fatal complication of mycotic dissecting aneurysm of the basilar artery following meningitis, which developed acutely in hospital, while on treatment. Antibiotic therapy had not altered the course of disease. It is advisable to investigate for presence of ruptured mycotic aneurysms or dissection in cases of bacterial meningitis leading to SAH.

Abstract
OBJECTIVE Intracranial infectious aneurysms (IIAs) are a rare clinical entity without a definitive treatment guideline. In this study, we evaluate the treatment options of these lesions based on our own clinical experience and review the current knowledge of therapy as portrayed in the literature. METHODS We conducted a single-center retrospective analysis of all patients with an IIA and performed a systematic review of the literature using the MEDLINE database. We undertook a comprehensive literature search using the OVID gateway of the MEDLINE database (1950-October 2015) using the following keywords (in combination): 'infectious', 'mycotic', 'cerebral aneurysm', 'intracranial aneurysm'. 1,721 potentially relevant abstracts were identified and 63 studies were selected for full review. The studies were analysed regarding ruptured versus unruptured aneurysms, aneurysm localization and treatment, as well as clinical and radiological outcome. RESULTS Our institutional series consisted of 6 patients (median age 57 [32-76]) treated between 2011 and 2015. All patients presented with ruptured IIAs located on the middle cerebral artery (MCA, 5 patients) and anterior cerebral artery (ACA, 1 patient). Five patients were treated by clipping and resecting the aneurysm, 1 patient underwent coiling. All patients received antibiotic therapy and 1 patient died. We further identified 814 patients (median age 35.5 [0-81]) in 63 studies. Locations of the aneurysms were mentioned in 55 studies. The most frequent locations of the aneurysms were: MCA (63.5%), posterior cerebral artery (14%), ACA (9.0%) and others (13.5%). Treatment for IIAs was described in 62 studies: antibiotic treatment (56.1%), a combination of antibiotics and surgery (20.9%) or antibiotics and endovascular treatment (23.0%). Outcome was mentioned in 82.4% of the patients with a mortality rate of 16.8%. An evaluation of treatment outcome was limited due to the heterogeneity of patients in the published case series. CONCLUSION Antibiotic therapy of patients with IIA is mandatory. However, due to the complexity of the disease and its accompanying comorbidities, a general treatment algorithm could not be defined. Analogous to non-mycotic aneurysms, further treatment decisions require an interdisciplinary approach involving neurosurgeons, interventionists and infectious disease specialists.

Abstract
Peripheral mycotic aneurysms (PMAs) are a relatively rare but serious complication of infective endocarditis (IE). We conducted the current study to describe and compare the current epidemiologic, microbiologic, clinical, diagnostic, therapeutic, and prognostic characteristics of patients with symptomatic PMAs (SPMAs). A descriptive, comparative, retrospective observational study was performed in 3 tertiary hospitals, which are reference centers for cardiac surgery. From 922 definite IE episodes collected from 1996 to 2011, 18 patients (1.9%) had SPMAs. Because all SPMAs developed in left-sided IE, we performed a comparative study between 719 episodes of left-sided IE without SPMAs and 18 episodes with SPMAs. We found a higher frequency of intravenous drug abuse, native valve IE, intracranial bleeding, septic emboli, multiple embolisms, and IE diagnostic delay >30 days in patients with SPMAs than in patients without SPMAs. The causal microorganisms were gram-positive cocci (n =10), gram-negative bacilli (n = 2), gram-positive bacilli (n = 3), Bartonella henselae (n = 1), Candida albicans (n = 1), and negative culture (n = 1). The median IE diagnosis delay was 15 days (interquartile range [IQR], 13-33 d) in the case of high-virulence microorganisms versus 45 days (IQR, 30-240 d) in the case of low- to medium-virulence microorganisms. Twelve SPMAs were intracranial and 6 were extracranial. In 10 cases (8 intracranial and 2 extracranial), SPMAs were the initial presentation of IE; the remaining cases developed symptoms during or after finishing parenteral antibiotic treatment. The initial diagnosis of intracranial SPMAs was made by computed tomography (CT) or magnetic resonance imaging in 6 unruptured aneurysms and by angiography in 6 ruptured aneurysms. The initial test in extracranial SPMAs was Doppler ultrasonography in limbs, CT in liver, and coronary angiography in heart. Four (3 intracranial, 1 extracranial) of 7 (6 intracranial, 1 extracranial) patients treated only with antibiotics died. Surgical resection was performed in 7 (3 intracranial, 4 extracranial) and endovascular repair in 4 (3 intracranial, 1 extracranial) patients; all of them survived. In conclusion, we found that SPMAs were a rare complication of IE that developed only in left-sided IE, and especially in native valves. Intracranial hemorrhage, embolism, multiple embolisms, and diagnostic delay of IE were more common in patients with SPMAs. The microbiologic profile was diverse, but microorganisms of low-medium virulence were predominant, and had a greater delayed diagnosis of IE than those caused by microorganisms of high virulence. SPMAs were often the initial presentation of IE. The most common location of SPMAs was intracranial. Noninvasive radiologic imaging techniques were the initial imaging test in intracranial unruptured SPMAs and in most extracranial SPMAs. Surgical and endovascular treatments were safe and effective. Endovascular treatment could be the first line of treatment in selected cases. Mortality was high in those cases treated only with antibiotics.

Abstract
Infective endocarditis is a serious disease of the endocardium of the heart and cardiac valves, caused by a variety of infectious agents, ranging from streptococci to rickettsia. The proportion of cases associated with rheumatic valvulopathy and dental surgery has decreased in recent years, while endocarditis associated with intravenous drug abuse, prosthetic valves, degenerative valve disease, implanted cardiac devices, and iatrogenic or nosocomial infections has emerged. Endocarditis causes constitutional, cardiac and multiorgan symptoms and signs. The central nervous system can be affected in the form of meningitis, cerebritis, encephalopathy, seizures, brain abscess, ischemic embolic stroke, mycotic aneurysm, and subarachnoid or intracerebral hemorrhage. Stroke in endocarditis is an ominous prognostic sign. Treatment of endocarditis includes prolonged appropriate antimicrobial therapy and in selected cases, cardiac surgery. In ischemic stroke associated with infective endocarditis there is no indication to start antithrombotic drugs. In previously anticoagulated patients with an ischemic stroke, oral anticoagulants should be replaced by unfractionated heparin, while in intracranial hemorrhage, all anticoagulation should be interrupted. The majority of unruptured mycotic aneurysms can be treated by antibiotics, but for ruptured aneurysms, endovascular or neurosurgical therapy is indicated.

Abstract
The authors report a rare case of cerebral hyperperfusion syndrome (HPS) following the excision of a mycotic aneurysm with superficial temporal artery-to-middle cerebral artery (STA-MCA) bypass. A 74-year-old woman with infective endocarditis presented with progressive cerebral infarction and subarachnoid hemorrhage due to a mycotic aneurysm, which was excised with a STA-MCA bypass. Postoperatively, the patient developed HPS that was considered to be exacerbated by a previous ischemic event. Therefore, cerebral hemodynamics should be evaluated before bypass surgery to prevent subsequent hyperperfusion.

Abstract
Mycotic aneurysms may arise in the setting of many local or systemic infections. Those of the intracranial circulation are especially worrisome due to their potential to compress vital neural structures and their propensity for rupture with consequent hemorrhage. Mycotic aneurysms of the intracavernous internal carotid artery (ICA) represent an exceedingly rare clinical entity, described in less than fifty published cases. Typically presenting as a cavernous sinus syndrome with signs and symptoms of the underlying infection, they are often missed initially, with diagnosis and treatment commencing for the triggering infection or confused with cavernous sinus thrombophlebitis, which may be additionally coexistent, confounding timely diagnosis of the aneurysmal disease. Compared to non-mycotic aneurysms of the intracavernous ICA, which typically have a benign course, the infectious etiology of the mycotic variety increases their tendency to rupture, precludes surgical clipping as a viable treatment option, and requires institution of prolonged antibiotic therapy prior to definitive intervention. Their critical location, friability, and propensity to occur bilaterally result in an unpredictable risk of rapid neurological decline and death, making the timing and specific nature of treatment a unique dilemma facing the treating physician. This review seeks to discuss the natural history of and management strategies for mycotic aneurysms of the intracavernous ICA with special emphasis on the role, safety, and efficacy of endovascular therapies.

Abstract
A 51-year-old man with a history of injection drug use presented to the emergency roomwith fevers, chills and headaches. Five months earlier, he had undergone bioprosthetic aortic valve replacement for infective endocarditis owing to Corynebacterium auricumosum involving a bicuspid aortic valve. Blood cultures obtained during current hospitalisation grew Haemophilus parainfluenzae and patient underwent a transesophageal echocardiogram that revealed a large mitral valve vegetation. Owing to persistent headache and right lower extremity weakness, MRI of the brain was performed which demonstrated multifocal, acute infarctions secondary to septic embolisation. He was initiated on parenteral antibiotics and experienced no further neurological setbacks. After 2 weeks of antibiotic therapy, he underwent bioprosthetic aortic and mitral valve replacement, aortic root debridement and replacement, and reconstruction of the intravalvular fibrosa without complication. He was discharged to a skilled nursing facility to complete six more weeks of intravenous ceftriaxone.

Abstract
OBJECTIVE
Although infectious complications of endovascular aneurysm treatment are in general rare, platinum coil therapy for patients with ruptured cerebral aneurysms and active bacteremia could be expected to carry increased risk. The literature on the timing and safety of endovascular treatment in this setting, however, is limited. In this report, the authors present a case of aneurysmal subarachnoid hemorrhage and active bacteremia in which intravenous antibiotics and early endovascular therapy were successfully used. A review of the literature is also provided.
CLINICAL PRESENTATION
A 79-year-old woman presented with Hunt-Hess grade 4, Fisher grade 3 + 4 subarachnoid hemorrhage. Blood cultures obtained on admission revealed gram-positive cocci, which later proved to be coagulase-negative Staphylococcus.
INTERVENTION
Intravenous cefepime and vancomycin were begun soon after admission. A right posterior communicating artery saccular aneurysm was identified on diagnostic cerebral angiography and was treated with bare platinum coils 28 hours after antibiotic therapy was initiated. An extended course of vancomycin was completed. No intracranial infectious complications were noted at 34-month clinical and radiographic follow-up.
CONCLUSION
This is the first case report to document the efficacy and safety of early endovascular coil embolization of a ruptured saccular cerebral aneurysm presenting in the context of active bacteremia. Review of the available literature suggests that a similar strategy for ruptured infectious aneurysms may also be safe. Further validation of this approach for both saccular and infectious aneurysms, however, is required.

Abstract
The histopathological characteristic of intracranial microbial aneurysm (MA)-infectious aneurysm is the presence of infection and destruction of the walls of the vessels. It can occur in the setting of predisposing infections that spread by endovascular mechanism (e.g., infective endocarditis) or extravascular mechanism (e.g., meningitis). MA is probably a better term than mycotic, infectious, or infective aneurysm as a wide variety of bacteria, fungi, mycobacteria, and virus can cause MA. Typically MAs are multiple, distal, and fusiform aneurysms, but the angiographic and clinical presentations can vary widely. The most common presentation of MA is intracranial bleed. CT angiography, MR angiography, or Digital subtraction angiography can be deployed to detect MA. By combining the clinical findings, imaging, and angiographic findings, it is possible to arrive at a correct diagnosis in most instances. MAs carry higher risk of rupture and fatal bleed when compared to other aneurysms. The treatment options include antimicrobial therapy, surgery, and endovascular therapy. The management strategy is based on large case series rather than controlled trials. All MA should receive appropriate antibiotic therapy. Ruptured MA with mass effect would require surgery in most situations, while those without mass effect and in non-eloquent locations could also be managed by endovascular therapy. Unruptured MA could be managed according to the size, location, and risk of bleeding-by antibiotic therapy, surgery, or endovascular therapy. Monitoring the resolution of the MA under antibiotic therapy by serial CT angiography is another option, but it carries higher risk of bleeding. Treatment of the underlying predisposing infection is an important component of therapy.

Abstract
BACKGROUND Intracranial infectious aneurysms (IA) are infrequent, but can be fatal. OBJECTIVES To compare the clinical profile of IAs associated with intravascular/systemic infection like infective endocarditis with that associated with local infections like meningitis, orbital cellulitis and cavernous sinus thrombosis. METHODS We analysed all cases of IA, treated in this Institute from 1976 to 2003, in order to identify prognostic factors. RESULTS There were 25 persons (mean age 24.8+/-17.3 years, males 17) with 29 IA (carotid circulation 19, vertebrobasilar circulation 10). Headache (83%) and fever (67%) were the most common presenting symptoms. In contrast to noninfectious aneurysms, intracerebral haemorrhage (60%) and focal signs were more common than subarachnoid haemorrhage (7%) with IA. Sources of infection were cardiac (10), meningitis (12), orbital cellulitis (2) or uncertain (1). Infective agents included bacteria (18), fungi (4), and tubercle bacilli (3). Fifteen IA were distal and 14 were proximal. IAs associated with meningitis were proximal (75%) while those associated with cardiac diseases preferentially involved carotid territory and were distal (p=0.013). The overall mortality was 32%. Survivors were younger than those who expired (p=0.015). Of the sixteen patients treated medically, seven recovered (44%), others (56%) had treatment failure (three died and six required surgery later). Another five patients underwent early surgery (one died). Mortality of IA was significantly higher with meningitis, fungal aetiology and vertebrobasilar location. CONCLUSIONS IAs associated with local infections like meningitis had different clinical profile as compared to IAs associated with intravascular/systemic infections like infective endocarditis.

Abstract
BACKGROUND Despite advances in medical, surgical, and critical care interventions, infective endocarditis remains a disease that is associated with considerable morbidity and mortality. The continuing evolution of antimicrobial resistance among common pathogens that cause infective endocarditis creates additional therapeutic issues for physicians to manage in this potentially life-threatening illness. METHODS AND RESULTS This work represents the third iteration of an infective endocarditis "treatment" document developed by the American Heart Association under the auspices of the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease, Council on Cardiovascular Disease of the Young. It updates recommendations for diagnosis, treatment, and management of complications of infective endocarditis. A multidisciplinary committee of experts drafted this document to assist physicians in the evolving care of patients with infective endocarditis in the new millennium. This extensive document is accompanied by an executive summary that covers the key points of the diagnosis, antimicrobial therapy, and management of infective endocarditis. For the first time, an evidence-based scoring system that is used by the American College of Cardiology and the American Heart Association was applied to treatment recommendations. Tables also have been included that provide input on the use of echocardiography during diagnosis and treatment of infective endocarditis, evaluation and treatment of culture-negative endocarditis, and short-term and long-term management of patients during and after completion of antimicrobial treatment. To assist physicians who care for children, pediatric dosing was added to each treatment regimen. CONCLUSIONS The recommendations outlined in this update should assist physicians in all aspects of patient care in the diagnosis, medical and surgical treatment, and follow-up of infective endocarditis, as well as management of associated complications. Clinical variability and complexity in infective endocarditis, however, dictate that these guidelines be used to support and not supplant physician-directed decisions in individual patient management.

Abstract
Giant mycotic pseudoaneurysms of the vertebral artery are extremely rare. Their management is technically challenging because of the distorted anatomy and intimate relation to the lower cranial nerves. We present a rare case of a 7-year-old boy referred to us by a pediatrician who was treating him for bacterial endocarditis. The pulsatile swelling measured 10 x 5 cm and was located in the left suboccipital triangle. The skin over the swelling was tethered to the underlying pulsatile swelling, suggesting prerupture syndrome. A contrast angiogram revealed a pseudoaneurysm from the third part of the left vertebral artery. Vegetations were seen on the tricuspid valve on echocardiography. Two-step surgery was performed under the cover of antibiotics. Excision of the aneurysm was done after ligation of the third part of the vertebral artery. The postoperative period was uneventful, and there was no neurologic deficit. Repeat magnetic resonance angiogram revealed no residual pseudoaneurysm. The histopathologic examination of the specimen was suggestive of mycotic aneurysm of left vertebral artery.

Abstract
INTRODUCTION mycotic intracranial aneurysms are a rare complication of infectious endocarditis. We report four cases of patients with endocarditis, complicated by an acute stroke, revealing a mycotic intracranial aneurysm. PATIENTS AND METHODS four men (aged range 24 to 63 year old) were admitted for endocarditis, complicated by ischemic stroke in two cases and hemorrhagic stroke in the two other cases, including one with subarachnoid hemorrhage. Neuroimaging disclosed a mycotic cerebral aneurysm in all four cases. DISCUSSION we will discuss the natural history and the management of mycotic intracranial aneurysm based on a review of the literature and our experience. Three therapeutic options are possible: medical treatment, surgery and endovascular embolisation. CONCLUSION management of mycotic intracranial aneurysms is still controversial, frequently requiring a multidisciplinary strategy with priority given to endovascular interventions.

Abstract
Abstract
OBJECTIVE AND IMPORTANCE:
Infectious (mycotic) aneurysms that do not resolve with medical treatment require surgical obliteration, usually requiring sacrifice of the parent artery. In addition, patients with mycotic aneurysms frequently need subsequent cardiac valve repair, which often necessitates anticoagulation. Three cases of awake craniotomy for microsurgical clipping of mycotic aneurysms are presented. Awake minimally invasive craniotomy using frameless stereotactic guidance on the basis of computed tomographic angiography enables temporary occlusion of the parent artery with neurological assessment before obliteration of the aneurysm.
CLINICAL PRESENTATION:
A 56-year-old woman presented with progressively worsening mitral valve disease and a history of subacute bacterial endocarditis and subarachnoid hemorrhage 30 years previously. A cerebral angiogram revealed a 4-mm left middle cerebral artery (MCA) angular branch aneurysm, which required obliteration before mitral valve replacement. The second patient, a 64-year-old woman with a history of rheumatic fever, had an 8-mm right distal MCA aneurysm diagnosed in the setting of pulmonary abscess and worsening cardiac function as a result of mitral valve disease. The third patient, a 57-year-old man with a history of fevers, night sweats, and progressive mitral valve disease, had an enlarging left MCA angular branch aneurysm despite the administration of antibiotics. Because of their location on distal MCA branches, none of the aneurysms were amenable to preoperative test balloon occlusion.
INTERVENTION:
After undergoing stereotactic computed tomographic angiography with fiducial markers, the patients underwent a minimally invasive awake craniotomy with frameless stereotactic navigation. In all cases, the results of the neurological examination were unchanged during temporary parent artery occlusion and the aneurysms were successfully obliterated.
CONCLUSION:
Awake minimally invasive craniotomy for an infectious aneurysm located in eloquent brain enables awake testing before permanent clipping or vessel sacrifice. Combining frameless stereotactic navigation with computed tomographic angiography allowed us to perform the operation quickly through a small craniotomy with minimal exploration.

Abstract
Intracavernous carotid mycotic aneurysms are rare and management is dictated by clinical presentation. This case involved a patient presenting with a symptomatic expanding proximal internal carotid artery aneurysm treated with antibiotics and balloon occlusion but with thromboembolic complications resulting in a fatal outcome. Points of discussion include difficulties faced in reaching a diagnosis, management options for mycotic aneurysms and the rationale in this case for choosing endovascular rather than surgical treatment. The use and limitations of trial balloon occlusion are discussed as well as complications of vessel occlusion, in particular thromboembolism. Also discussed is the importance of surveillance imaging and the impact of sepsis on overall management.

Abstract
A 21-year-old woman with severe mitral valve regurgitation due to infectious endocarditis was transferred to our institute in a deep coma with intracerebral hemorrhage and acute subdural hematoma. She had no history of head injury. Brain computed tomography revealed left frontoparietal intracerebral hematoma and adjacent acute subdural hematoma that were evacuated on the day of admission, but the distal middle cerebral artery (MCA) aneurysm remained undetected. Follow-up cerebral angiography demonstrated the distal MCA aneurysm, which had enlarged by 25% at 2 weeks following the first operation. The aneurysm originated from a branch of the angular artery and was successfully resected on Day 22. Histological examination of the aneurysm section showed no infectious nature, but the final diagnosis was infectious intracranial aneurysm based on the presence of infectious endocarditis.

Abstract
OBJECTIVE The purpose of this study was to better define the management of intracranial infectious aneurysms. METHODS We present a retrospective review of the management of 16 patients with intracranial infectious aneurysms. The mean follow-up period was 86 months. RESULTS None of the patients had a rehemorrhage during antibiotic treatment. The mortality and long-term outcome from ruptured intracranial infectious aneurysms may be better than previously thought. There was no significant difference in long-term outcome between patients with single or multiple infectious aneurysms or between patients who underwent surgical resection and those who were treated only with antibiotics. CONCLUSION Operative treatment should be pursued for patients with ruptured infectious aneurysms. Patients with unruptured intracranial infectious aneurysms should be observed during antibiotic therapy and followed up with cerebral angiography. Surgical resection should be considered if the aneurysm enlarges and the patient's general medical condition allows general anesthesia to be tolerated.

Abstract
Central nervous system infections in injection drug users are often devastating in terms of excess morbidity and mortality. In injection drug users with infective endocarditis, embolization from infected valvular vegetations may cause cerebral infarction, intracranial hemorrhage, and the formation of brain abscess. Focal intracranial infections (i.e., brain abscess and spinal epidural abscess) may occur in the absence of infective endocarditis, resulting from bacteremia that seeds the brain or epidural space. Antimicrobial therapy, combined with surgical intervention, may be essential to improve outcome from these neurologic complications. Toxin-mediated diseases (especially tetanus and wound botulism) are also seen in injection drug users. Inoculation of Clostridium spp at injection sites may lead to toxin generation and disease. Clinicians must maintain a high level of suspicion for these diagnoses in injection drug users.

Abstract
Cases of subarachnoid haemorrhage (SAH) as a presenting feature or soon after initiation of antibiotics in infectious endocarditis (IE) have been reported. However, most had documented mycotic aneurysms as the source of haemorrhage. Reports of IE associated with SAH of unclear source are rare. A case of SAH associated with IE is reported. We also reviewed our data set on neurological complications of IE at Mayo Clinic Rochester from 1980 to 1996 for additional cases. In addition to the index case, we identified seven cases of SAH amongst 489 patients (1%) with IE for a total of eight cases. In six patients, initial cerebral angiography, magnetic resonance angiography or autopsy did not show aneurysm or other aetiology for the SAH. A mycotic aneurysm was noted in one case and the other patient had an unruptured mycotic aneurysm of the tip of basilar artery. SAH was located in the basal cistern in two patients, sylvian fissure in three, and hemispheric sulci in three. SAH is an uncommon complication of IE, and in the setting of IE a specific cause, such as mycotic aneurysm, may not be identified.

Abstract
INTRODUCTION Cerebral hemorrhages due to rupture of mycotic aneurysms are rare but severe complications of infective endocarditis. We report two cases with a good outcome. EXEGESIS The first patient presented with a parieto-occipital hematoma which occurred in the course of a relapsing infective endocarditis due to Streptococcus mitis. She fully recovered after neurosurgical treatment. In the second case, a right frontal hematoma revealed two mycotic aneurysms and an infective endocarditis due to Streptococcus gordonii. Motor weakness partially recovered after antibiotic therapy and angiography demonstrated complete resolution of aneurysms. CONCLUSION Ruptured mycotic aneurysms are poor prognosis factors in infective endocarditis. Adapted antibiotic therapy is the first-intent treatment. Neurosurgery is indicated when hematomas are poorly tolerated and in cases requiring anticoagulant therapy.

Abstract
PURPOSE To evaluate the endovascular treatment (EVT) of mycotic aneurysms (MAs). MATERIALS AND METHODS Clinical and radiologic data of 18 MAs treated with EVT were retrospectively reviewed. There were 14 patients (11 men, three women), ranging in age from 28 to 64 (mean age, 44 years). All patients had endocarditis and positive blood culture. The aneurysms were located within the distal cerebral circulation (n = 13) or in the circle of Willis (n = 5). There were 12 ruptured aneurysms and six unruptured aneurysms. Distal or fusiform aneurysms were treated by means of parent vessel occlusion. Proximal saccular aneurysms were selectively treated. RESULTS Endovascular treatment was successful for all aneurysms. No aneurysm bled after embolization during clinical follow-up. Follow-up angiograms obtained in 11 of 14 patients 6 months to 2 years after the procedures showed stable occlusions. Transient complications occurred in two cases, with worsening of hemiparesis and quadrantanopia. Five patients underwent surgical cardiac valve replacement within 1 week of EVT without neurologic complications. The late clinical outcome was normal neurologic status (n = 9) or permanent disability that was related to the initial stroke (n = 5). CONCLUSION EVT is a reliable and safe technique that should be considered at the time of diagnosis of cerebral mycotic aneurysms.

Abstract
Infective endocarditis can often involve the nervous system, resulting in stroke, intracerebral hemorrhage, infectious aneurysm formation, cerebral abscess, and spinal epidural infection. Many of these problems require neurosurgical attention. Modern advances in neuro- surgical critical care, computerization, instrumentation, and radiologic imaging have affected the treatments available to patients with neurosurgical manifestations of infective endocarditis. This paper is a brief overview of the contemporary management of neurosurgical complications of infective endocarditis.

Abstract
OBJECTIVE To implement an algorithm for and assess multimodality (medical, endovascular, and microsurgical) treatment of patients with infectious intracranial aneurysms. METHODS Twenty patients with 27 infectious aneurysms were treated during a 10-year period. Bacterial endocarditis was the most common cause (65%). Most aneurysms presented with rupture (75%), and the middle cerebral artery was the most common location (70%). RESULTS Five patients were treated endovascularly, with direct coiling for three patients and parent artery occlusion for two patients. Ten patients (15 aneurysms) were treated surgically, with 6 aneurysms being trapped/resected, 2 trapped/bypassed, 4 clipped, and 3 wrapped. Five patients were treated medically. Treatment-associated neurological morbidity was observed for two patients (10%), and two patients died (10%). Good outcomes were observed for 16 patients (80%). CONCLUSION Factors that guide management decisions for these patients include aneurysm rupture, hematomas with increased intracranial pressure, and the eloquence of brain tissue supplied by the parent artery. Patients with unruptured infectious aneurysms are initially treated medically, with antibiotics and serial angiography. Patients with ruptured aneurysms that are not associated with hematomas and that do not involve eloquent vascular territory are treated endovascularly. Patients with ruptured aneurysms are treated surgically when there is a hematoma or the risk of ischemic complications in eloquent territory. Therefore, endovascular therapy is the first option for patients in stable condition with ruptured aneurysms; surgical therapy is the first option for patients in unstable condition with ruptured aneurysms and the second option for patients in stable condition who experience failure of endovascular therapy. Medically treated patients with enlarging or dynamic unruptured aneurysms also require direct surgical or endovascular intervention. Favorable patient outcomes can be achieved with this multimodality management.

Abstract
AIM This study is an analysis of angiographic findings in 17 patients with infective aneurysms who presented with intracranial haemorrhage and reviews the management and outcome in the context of the existing literature. MATERIALS AND METHODS A retrospective study of infective aneurysms in 17 patients was carried out. Cranial angiography was performed in all patients. The location, size and outline of aneurysms were analysed. Ten patients were managed conservatively and six patients underwent surgery for the ruptured infective aneurysms and were followed up for a period of 35.8 months and 23 months, respectively. RESULTS Twenty-two aneurysms were identified (five unruptured) in 17 patients. Twenty aneurysms (90. 9%) were distal in location and two (9.1%) proximal. Sixty percent were in the posterior circulation with 55% in the posterior cerebral artery (PCA) territory, 27.3% in the middle cerebral artery (MCA) territory and 9.1% in the anterior cerebral artery (ACA) territory. Fourteen aneurysms were small (3-5 mm) and eight were medium sized (6-9 mm). 72.7% of aneurysms had irregular outline and 27.3% regular outline. Out of the 10 ruptured aneurysms managed conservatively, eight resolved. One patient died, presumably due to rebleed, and one had infarction due to parent vessel thrombosis. Six aneurysms were surgically managed with good results. Of the five unruptured aneurysms one was surgically managed and the remaining four conservatively managed patients did not bleed during follow-up. CONCLUSION Patients with ruptured infective aneurysms fared well with medical management and the outcome in this series is better than that reported in literature. Patients on conservative management, however, need closer monitoring with angiographic follow-up. Active management is required with enlarging or persisting aneurysms.

Abstract
A case is reported of a brain abscess and an intracranial mycotic aneurysm associated with infective endocarditis caused by streptococcus intermedius. A 60-year-old man with a history of fever presented aphasia and right hemiparesis. A computed tomographic scan of the head revealed a low-density area with ring enhancement in the left parietal lobe consistent with a brain abscess. An angiography demonstrated an aneurysm on the distal branch of the middle cerebral artery compatible with a mycotic aneurysm. Doppler echo cardiography showed severe mitral regurgitation by chordal ruptures. The brain abscess and intracranial mycotic aneurysm were resolved under appropriate antibiotic therapy for eight weeks. Then, the mitral valve was reconstructed by replacement of the chordae tendineae with expanded polytetrafloroethylene suture and annuloplasty. The patient had no neurologic deficit except for paresthesia in the right hand, and had no mitral regurgitation at discharge.

Abstract
Less than 10% of all aneurysms affecting the arterial cerebral circulation are mycotic in nature. They occur in the setting of bacterial endocarditis and are the cause of considerable morbidity and mortality of affected patients. In selected cases surgery may play a curative role in the treatment plan. These aneurysms frequently arise in distal arterial branches, and their localization during surgery may at times prove laborious. We report the case of a mycotic aneurysm of a distal branch of the anterior cerebral artery surgically treated with the help of angiographic stereotactic localization. Stereotaxy should thus be regarded as a pertinent adjunct in selected cases of surgical treatment of distal mycotic cerebral aneurysms.

Abstract
We report three patients with bacterial intracranial aneurysms treated by the endovascular approach: two presented with sudden severe neurological deficits after a diagnosis of endocarditis; the other had suspected vasculitis. CT showed an intracerebral haematoma in all cases; angiography revealed bacterial aneurysms of distal branches of the middle cerebral artery in one. Because of the patients' condition and the location of the aneurysms, endovascular treatment was considered the fastest and safest treatment. Hyperselective catheterisation of the parent branch, close to the aneurysm, was performed with a microcatheter. A small amount of glue was injected to occlude both the aneurysm and a short segment of the diseased vessel. Follow-up angiography revealed occlusion of the aneurysm in all cases. One patient recovered completely; one recovered over some months, with neurological deficit due to the haematoma. The third patient suddenly worsened and died 9 days after treatment for a contralateral haematoma, due to rupture of a new bacterial aneurysm of the middle cerebral artery. Endovascular occlusion of the aneurysm and parent vessel may be an alternative to surgery in selected, severe cases of deep or distal bacterial intracranial aneurysms.

Abstract
Intracranial mycotic aneurysm is a rare complication in patients with infective endocarditis occurring in about 2% to 10% of cases. Although the risk of rupture is about 1.7%, it is usually a catastrophic event with a fatality rate of 80%. Neurological deficits secondary to cortical involvement are common, given the frequency of intralobar hemorrhage. We report two cases of intracerebral hemorrhage caused by ruptured intracranial mycotic aneurysms. Both had involvement of the right frontoparietal lobes with resultant left hemiparesis, left homonymous hemianopia, and impairments of cognition and perceptual function. Despite intensive rehabilitation, their functional outcomes were less than satisfactory as they needed assistance in self-care activities and mobility on discharge.

Abstract
The Steiner-Lindquist laser intra-operative guidance method is described and its application in the surgical treatment of mycotic aneurysm is presented. Three illustrative cases of distal middle cerebral artery aneurysms are reported. The authors argue that all ruptured mycotic aneurysms should be treated surgically. The laser-guided stereotactic approach is presented as simple, flexible and reliable method to improve safety and accuracy of the operation in these cases. In our experience it compares favorably with previously described stereotactic techniques.

Abstract
Solid granulomas and aneurysms caused by Aspergillus of the central nervous system are rare. A fungal aneurysm is usually situated proximally on the intracranial vessels and is often fatal. We report a case in which a ruptured aneurysm arose from the distal portion of the left posterior inferior cerebellar artery (PICA) in the course of treatment for chronic meningitis forming a granuloma at the left pyramis. After biopsy of the granuloma, he presented subarachnoid hemorrhage caused by a saccular PICA aneurysm. Histologic examination of the aneurysmal wall and the granuloma revealed infection with Aspergillus hyphae. The literature regarding the management of aspergillotic aneurysm is reviewed.

Abstract
The aim of this study was to evaluate the role of endovascular treatment for intracranial mycotic aneurysms. The clinical and angiographic features of three patients with endocarditic vegetation (two with Streptococcus viridans and one with Staphylococcus) were reviewed retrospectively. Patients were selected for this treatment according to the clinical setting and aneurysm location. In two cases, selective catheterization of a distal middle cerebral and posterior cerebral artery branch with a microcatheter followed by superselective amobarbital testing of the parent vessel was preliminary to the occlusion of that vessel with autologous clot or glue. The third patient was treated by selective occlusion of the aneurysm by intra-aneurysmal placement of platinum minicoils. Two patients presented with intracranial hemorrhage and in one the lesion was found on computerized tomography. All three aneurysms had been excluded from the circulation at the 6-month follow-up review. The only complication from the procedure, despite the septic nature and distal localization, was balloon deflation in one patient, who was successfully retreated with coils. Endovascular embolization is indicated in patients who are at risk of hemorrhage and cannot undergo the standard procedure. The superselective amobarbital test allows selection of patients who will tolerate distal vessel occlusion. This endovascular procedure represents a safe and effective treatment for these lesions.

Abstract
BACKGROUND AND PURPOSE Patients with infective endocarditis may develop intracranial mycotic aneurysms. Whether these patients should undergo cerebral angiography followed by prophylactic surgery if an aneurysm is detected is an unresolved question. METHODS We estimated the probability of survival 12 weeks after the diagnosis of infective endocarditis on the basis of data available in the literature. RESULTS For a 40-year-old female patient with right-sided hemiplegia, the 12-week survival is estimated to be 83.75% without angiography and 83.65% with angiography; the specific mortality of intracranial mycotic aneurysms is relatively small but increases by 40% (from 0.25% to 0.35%) if angiography is performed. The risk of aneurysm rupture in infective endocarditis and the mortality from rupture appear to be the most important factors that affect the analysis. CONCLUSIONS Cerebral angiography should not be performed routinely in patients with infective endocarditis. Specific subgroups in whom such a policy might be beneficial have not yet been identified.

Abstract
Seventeen patients were treated for 28 documented cerebral mycotic aneurysms. Initial neurological symptoms were attributable to aneurysm rupture in only 7 patients, and in 3 of them symptoms did not suggest subarachnoid hemorrhage. Six patients presented with embolic infarction and 1 with meningitis; in 3 patients it was uncertain if aneurysm rupture occurred. Four patients had rupture of at least one aneurysm while receiving appropriate antibiotic treatment and another had rupture at the conclusion of therapy. Of 20 aneurysms followed angiographically or with computed tomography during medical treatment, 10 became smaller or disappeared and 10 remained unchanged or enlarged, 1 with fatal rupture. Eight ruptured aneurysms were surgically excised; 2 of the patients with ruptured aneurysms died and 2 had residual aphasia or cognitive impairment. All 4 patients whose only surgery was for an unruptured aneurysm made uneventful recoveries. Recognizing the retrospective and anecdotal nature of our data and the differing views of previous investigators, we recommend: (1) that careful neurological examination, computed tomography, and (unless contraindicated) lumbar puncture be performed on any patient with endocarditis; (2) that those with neurological abnormalities not attributable to systemic toxicity, including pleocytosis in the cerebrospinal fluid or apparent infarction on computed tomographic scans, undergo four-vessel cerebral angiography; (3) that single accessible mycotic aneurysms in medically stable patients be promptly excised, with individualization of multiple or proximal aneurysms; and (4) that repeat angiography be performed at the conclusion of antibiotic therapy in patients requiring long-term anticoagulation.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We describe a patient who developed bilateral cavernous sinus septic thrombosis secondary to a suppurative lesion on the left cheek. Despite clinical improvement, left oculomotor symptoms recurred suddenly. A carotid artery aneurysm within the cavernous sinus was diagnosed by means of magnetic resonance imaging and confirmed by digital angiography. Follow-up angiograms showed an initial decrease in the aneurysm size, with subsequent enlargement. A latex contrast-filled balloon was successfully placed within the aneurysm, preserving the carotid parent artery blood flow. Our case illustrates the usefulness of the detachable balloon technique in the treatment of bacterial aneurysms of the cavernous sinus as an alternative treatment to carotid artery ligation.

Abstract
A case of intracavernous aneurysm secondary to septic cavernous sinus thrombosis demonstrating sequential dynamic angiographic changes is reported. Serial angiograms of a 32-year-old man with septic cavernous sinus infection revealed a normal study, stenosis, recovery of stenosis, and aneurysmal formation. Superficial temporal-middle cerebral artery anastomosis and internal carotid artery ligation were performed because of progressive ophthalmoplegia. Neurological deficit rapidly disappeared. Anigiographic changes and surgical treatment of septic cavernous sinus thrombosis are discussed.

Abstract
A case is reported in which a mycotic aneurysm of the supraclinoidal portion of the internal carotid artery formed as the result of suprasellar infection following transsphenoidal surgery. The source of infection was thought to be a maxillary sinusitis. The aneurysm was treated with systemic antibiotic therapy and disappeared 4 months after the operation. Repeated angiography showed the whole course from the formation to the disappearance of the aneurysm and was valuable in the treatment of intracranial mycotic aneurysms.

Abstract
A case of repeated intracranial aneurysmal rupture occurring despite successful treatment of infective endocarditis is reported. While the valvular source of emboli was eradicated and serial angiograms documented no further aneurysms after resection of the primary lesion, the formation and rupture of multiple septic aneurysms occurred 9 months later in the opposite hemisphere. A relationship to damage of the cerebral vasculature by immune complexes is suggested as one possible explanation for this unusual occurrence. This implies that some patients with infective endocarditis may be at permanent risk for the formation and rupture of mycotic intracranial aneurysms, despite successful treatment of the primary cardiac lesion.

Abstract
Analysis of 17 patients with infective endocarditis and intracranial hemorrhage yielded several different mechanisms of bleeding. Nine of 15 (60%) symptomatic intracranial hemorrhages occurred within 48 hours of admission and 3 more (20%) after hospital discharge. In 7 patients with Staphylococcus aureus endocarditis, symptomatic intracranial hemorrhage occurred within 48 hours of admission and resulted from septic arteritis in all 3 examined pathologically. Secondary hemorrhagic transformation (hemorrhagic infarction) was asymptomatic in 2 nonanticoagulated patients but was associated with clinical worsening in 2 anticoagulated patients. Anticoagulation potentially contributed to intracranial hemorrhage in 4 of the 17 patients (24%). Proven mycotic aneurysms were present in only 2 patients (12%), 1 of whom presented with massive, fatal intracranial hemorrhage. Mycotic aneurysms amenable to surgery are uncommon and underlie only a fraction of intracranial hemorrhages in infective endocarditis.
