Abstract
Spinal epidural abscess (SEA) is an abscess that forms between the dura mater and vertebrae. SEA is characterized by back pain and neuropathy associated with fever, of which early diagnosis and treatment are necessary to avoid irreversible neurological sequelae. However, its diagnosis is often difficult because specific symptoms are rarely present in the early stages of the disease. A 25-month-old boy, healthy by nature and free of risk factors, was referred and admitted for fever symptoms only, without back pain or neurological symptoms. We focused on the residual activation of the coagulation-fibrinolytic system, which was contrary to the response to therapy, and were able to establish a diagnosis of SEA. After the initiation of antibiotics, the patient responded well to treatment and made a mild recovery without the need for surgical intervention. To date, there are no reported cases of SEA with only febrile symptoms without localized spinal cord tenderness. SEA is easily overlooked and should be considered in the differential diagnosis of pediatric fever of unknown origin. Although imaging studies have drawbacks, such as radiation exposure and sedation, they should be immediately performed if SEA is suspected.

Abstract
Aspergillus spinal epidural abscess (ASEA) is a rare, life-threatening condition that can cause spinal cord compression with neurologic deficits. The diagnosis of ASEA can be challenging due to the atypical clinical presentation and low prevalence. We describe the successful management of a rare, immunocompetent, 85-year-old male with ASEA at the T12-L1 and L1-L2 levels and present a review of the literature. Based on most case reports and our knowledge, this is a rare presentation of ASEA in a patient without systemic symptoms, leukocytosis, or a history of immunosuppressive status due to chronic steroid use. The patient presented with multiple falls and lower extremity paraparesis with near-complete paralysis of the right lower extremity for a duration of three months. Systemic symptoms of infection were absent and standard lab evaluations were unremarkable. CT imaging identified cord signal changes at the level of T10-T11 and a contrast block at L1 suspicious for spinal stenosis and impingement. During lumbar spine exploration, purulent fluid consistent with an abscess was found in the epidural space. Cultures were forwarded to microbiology and returned with Aspergillus. Postoperatively, Infectious Disease (ID) recommended treatment with voriconazole, cefepime, and vancomycin, which yielded gradual symptom improvement. The successful management of ASEA requires a multidisciplinary approach involving neurosurgeons, infectious disease specialists, radiologists, and physical therapists. Clinicians should be aware of the possibility of ASEA regardless of systemic symptoms, and early diagnosis and prompt treatment with surgical decompression and appropriate antifungal therapy are imperative for successful management.

Abstract
Metastatic epidural spinal cord compression develops in 5-10% of patients with cancer and is becoming more common as advancement in cancer treatment prolongs survival in patients with cancer (1-3). It represents an oncological emergency as metastatic epidural compression in adjacent neural structures, including the spinal cord and cauda equina, and exiting nerve roots may result in irreversible neurological deficits, pain, and spinal instability. Although management of metastatic epidural spinal cord compression remains palliative, early diagnosis and intervention may improve outcomes by preserving neurological function, stabilizing the vertebral column, and achieving localized tumor and pain control. Imaging serves an essential role in early diagnosis of metastatic epidural spinal cord compression, evaluation of the degree of spinal cord compression and extent of tumor burden, and preoperative planning. This review focuses on imaging features and techniques for diagnosing metastatic epidural spinal cord compression, differential diagnosis, and management guidelines.

Abstract
Spinal epidural abscess (SEA) is a rare and potentially devastating neurologic disease that is commonly treated with neurosurgical decompression and evacuation. We describe the case of an 11-month-old immunocompetent infant who presented with a large multiloculated methicillin-resistant Staphylococcus aureus abscess in the left lung apex with likely mediastinal involvement, extending into the epidural space from C7 down to L2 causing cord compression which was successfully treated with percutaneous placement of an epidural drainage catheter and antibiotic therapy. Although there are rare reports of percutaneous drainage of SEAs, to our knowledge, there are no reports of successful use of percutaneous indwelling catheters resulting in the complete resolution of an SEA. Holo-spinal epidural abscess in an infant is an extremely rare disease with limited literature available regarding the best practice for its treatment. Multiple considerations must be taken into account when weighing the different treatment options ranging from surgical decompression to conservative management with antibiotic therapy. We present a unique case of successful treatment with percutaneous epidural drain placement. This provides a reasonable alternative for management in children for whom surgical decompression carries multiple risks for complications both acutely and delayed.

Abstract
Aspergillus spinal epidural abscess (ASEA) is a rare entity that may mimic Pott's paraplegia as it commonly affects immunocompromised patients. We present one institutional case of ASEA with concomitant review of the literature. A 58-year-old female presented with intermittent low back pain for 10 years recently aggravated and with concurrent spastic paraparesis, fever, and weight loss. Emergent magnetic resonance imaging (MRI) showed T11–T12 epidural abscess with discitis and osteomyelitis. After empirical treatment with antibiotics, computed tomography-guided, percutaneous biopsy with drainage was performed, showing granulomatous tubercular-like collection. Antitubercular therapy was initiated, but after 1 month, the patient's condition deteriorated. Repeat MRI showed growth of the spinal epidural abscess with significant cord compression and vertebral osteomyelitis. T11–T12 laminectomy and tissue removal were performed with a posterior midline approach. Tissue histopathology showed necrotic debris colonies of Aspergillus spp. Antifungal therapy was started, and the patient rapidly improved. ASEA may mimic Pott's disease at imaging, leading to immediate start of antitubercular treatment without prior biopsy, leading to severe worsening of patients’ clinical status. Cases of ASEA should be considered at pretreatment planning, opting for biopsy confirmation before treatment initiation so to prevent the occurrence of fatal infection-related complications.

Abstract
Background: Spondylodiscitis caused by Aspergillus spp. is a rare but life-threatening clinical entity. However, a consensus on diagnostic criteria and most effective medical management is still missing. The present study is a review of all published cases of spondylodiscitis caused by Aspergillus spp., in an effort to elucidate epidemiology, patients’ characteristics, andand the medical and surgical treatment options and their effectiveness. Methods: A thorough review of all existing spondylodiscitis cases caused by Aspergillus was performed. Data regarding demographics, responsible fungus, time between symptoms’ onset and firm diagnosis, antifungal treatment (AFT), surgical intervention, andand the infection’s outcome were investigated. Results: A total of 118 Aspergillus spondylodiscitis cases, yielding 119 Aspergillus spp. isolates, were identified in the literature. The patients’ mean age was 40.6 years. Magnetic resonance imaging (MRI) (after its introduction) indicated the diagnosis in most cases (66.7%), while definite diagnosis was established through cultures in the majority of cases (73.7%). Aspergillus fumigatus was isolated in most cases (73; 61.3%), followed by Aspergillus flavus (15; 12.6%) andand Aspergillus nidulans and terreus (7; 5.9%, each). The mean time between symptoms’ onset and diagnosis was 5.7 months. Amphotericin B was the preferred antifungal regiment (84 cases; 71.2%), followed by voriconazole (31; 26.3%), and the mean AFT duration was 6.1 months. The final outcome was successful in 93 cases (78.8%). Furthermore, 77 patients (65.3%) underwent surgery. Conclusions: Spondylodiscitis caused by Aspergillus spp. represents a clinical challenge, requiring a multidisciplinary approach. The present review has shown that prolonged AFT has been the standard of care of the studied cases, while surgical treatment seems to play an important role in selected patents.

Abstract
Spinal epidural space is a real anatomic space located outside the dura mater and within the spinal canal extending from foramen magnum to sacrum. Important contents of this space are epidural fat, spinal nerves, epidural veins and arteries. Due to close proximity of posterior epidural space to spinal cord and spinal nerves, the lesions present with symptoms of radiculopathy and/or myelopathy. In this pictorial essay, detailed anatomy of the posterior epidural space, pathologies affecting it along with imaging pearls to accurately diagnose them are discussed. Various pathologies affecting the posterior epidural space either arising from the space itself or occurring secondary to vertebral/intervertebral disc pathologies. Primary spinal bone tumors affecting the posterior epidural space have been excluded. The etiological spectrum affecting the posterior epidural space ranges from degenerative, infective, neoplastic - benign or malignant to miscellaneous pathologies. MRI is the modality of choice in evaluation of these lesions with CT scan mainly helpful in detecting calcification. Due to its excellent soft tissue contrast, Magnetic Resonance Imaging is extremely useful in assessing the pathologies of posterior epidural space, to know their entire extent, characterize them and along with clinical history and laboratory data, arrive at a specific diagnosis and guide the referring clinician. It is important to diagnose these lesions early so as to prevent permanent neurological complication.

Abstract
Background Spinal epidural abscess (SEA) in children is a rare condition with dangerous sequelae, and with only 22 other cases reported in the literature, treatment algorithms are poorly understood. Quick identification of the classic tried of sepsis, back pain and neurological deficit is critical. Source identification difficult and often cannot be identified. Reported pathogens include varicella-zoster virus, S. aureus, and S pyogenes. Case description We report a case of spontaneous pediatric SEA in a 22-month old female without obvious neurologic deficit, who underwent a T10-11 decompressive laminotomy and evacuation of abscess and subsequent 3-week course of intravenous ceftriaxone for culture positive S. pyogenes Outcome The patient showed marked improvement in symptoms after decompression. 5 weeks postoperatively after transitioning from intravenous ceftriaxone to oral ceftin, the patient redeveloped a deep space infection and was taken back for a repeat debridement. The cultures from this procedure were negative and the patient was discharged on oral clindamycin. Conclusions Pediatric spontaneous SEA is a rare condition and early diagnosis and surgical intervention if indicated can prevent dangerous sequelae. Further studies into the surgical indications for decompression will aid in algorithmic decision making.

Abstract
Objective Vertebral aspergillosis is quite rare conditions, often misdiagnosed, that requires long-term antibiotic therapy, and sometimes, surgical treatments. The present investigations were aimed to investigate the epidemiology, clinical-radiological aspects, treatment protocols, and outcomes of Aspergillus-mediated vertebral osteomyelitis.
Methods A systematic review of the pertinent English literature according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed. The research was conducted on Cochrane library, MEDLINE, PubMed, and Scopus using as search-terms “Aspergillus,” “vertebral osteomyelitis,” “spondylodiscitis,” “spine infection.” A case of vertebral aspergillosis conservatively managed was also reported.
Results Eighty-nine articles were included in our systematic review. Including the reported case, our analysis covered 112 cases of vertebral aspergillosis. Aspergillus fumigatus was isolated in 68 cases (61.2%), Aspergillus flavus in 14 (12.6%), Aspergillus terreus in 4 (3.6%), Aspergillus nidulans in 2 (1.8%). Seventy-three patients (65.7%) completely recovered at the last follow-up evaluation; in 7 patients (6.3%) radiological signs of chronic infection were reported, whereas 32 patients (28.8%) died during the follow-up.
Conclusion This systematic review summarized the state of the art on vertebral aspergillosis, retrieving data on clinical features, diagnostic criteria and current limitations, treatment alternatives, and their outcomes.

Abstract
A 9-month-old healthy female presented during winter to the emergency department with a chief complaint of fever and prominent respiratory symptoms. She was discharged on oseltamivir with a presumptive diagnosis of influenza. She returned to the emergency department 2 days later with continued fever and more upper respiratory symptoms. She was admitted for intravenous hydration to the observation unit with a diagnosis of viral illness (with viral testing that returned positive for adenovirus) and dehydration. When her high fevers continued, bloodwork that was concerning for leukocytosis, elevated inflammatory markers, and elevated alkaline phosphatase was obtained. During her workup for fever, a full body magnetic resonance imaging was performed, which revealed the diagnosis of a C3 to L5 spinal epidural abscess. This case demonstrates the difficulty of making this important diagnosis in a preverbal child presenting with a concurrent virus during winter viral season.

Abstract
BACKGROUND Pediatric spinal epidural abscess is a major suppurative infection of the central nervous system. It is an extremely rare pathology carrying serious risk of permanent neurological sequelae if is not properly treated. METHODS AND RESULTS All the pertinent literature was analyzed, focused on pediatric cases of spinal epidural abscess and its peculiar features. Two illustrative cases are also presented. The first case is that of a 9-year old girl who took medical attention, when she was already paraplegic. Despite prompt surgical evacuation and good neuroradiological outcome and intensive rehabilitation, motor deficits did not recover after surgery. The second case was that of a 14-year old girl who presented with fever, neck pain, and torticollis. Prompt diagnosis, decompressive surgery, and 6 weeks of antibiotics allowed good neurological outcome. CONCLUSIONS The management of spinal epidural abscess includes evacuation of the abscess with decompression of the spinal cord and prolonged antibiotic treatment. The presence of neurological deficit and the delay in the initiation of proper treatment are the two factors that more worsen prognosis.

Abstract
A 12-year-old girl presented with a spinal epidural abscess (SEA), an unusual emergent infectious disease that often requires surgical intervention. Its nonspecific symptoms and rarity in pediatric patients frequently delay the diagnosis until neurologic symptoms develop. This patient had only fever without back pain or neurologic symptoms at the first visit. Whole-body CT later diagnosed a SEA, which was treated by antibiotics only. No neurologic deterioration was observed, and the fever and now-present pain gradually diminished. Early diagnosis of a SEA is important to avoid the development of symptoms. Despite its irradiation to the patient, CT might be useful for providing an early diagnosis in the absence of neurologic symptoms.

Abstract
BACKGROUND CONTEXT Fungal spinal epidural abscess (FSEA) is a rare entity with high morbidity and mortality. Reports describing the clinical features, diagnosis, treatment, and outcomes of FSEA are scarce in the literature. PURPOSE This study aimed to describe the clinical features, diagnosis, treatment, and outcomes of FSEA. STUDY DESIGN This study is designed as a retrospective clinical case series. PATIENT SAMPLE A continuous series of patients with the diagnosis of FSEA who presented at our institution from 1993 to 2016. METHODS We reviewed the electronic medical records of patients with SEA who were treated within our hospital system from 1993 to 2016. We only included SEA cases that were due to fungi. We also reviewed FSEA cases in the English language literature from 1952 to 2017 to analyze the features of FSEA. RESULTS From a database of 1,053 SEA patients, we identified 9 patients with FSEA. Aspergillus fumigatus was isolated from 2 (22%) patients, and Candida species were isolated from 7 (78%). Focal spine pain, neurologic deficit, and fever were demonstrated in 89%, 50%, and 44% of FSEA cases, respectively. Five of nine cases involved the thoracic spine, and eight were located anterior to the thecal sac. Three cases had fungemia, six had long symptom duration (>2 weeks) prior to presentation, seven had concurrent immunosuppression, and eight had vertebral osteomyelitis. Additionally, one case had residual motor deficit at last follow-up, one had S1 sensory radicular symptoms, two suffered recurrent FSEA, two died within hospitalization, and two died within 90 days after discharge. CONCLUSIONS In summary, the classic diagnostic triad (focal spine pain, neurologic deficit, and fever) is not of great clinical utility for FSEA. Biopsy, intraoperative tissue culture, and blood culture can be used to diagnose FSEA. The most common pathogens of FSEA are Aspergillus and Candida species. Therefore, empiric treatment for FSEA should cover these species while definitive identification is pending. FSEA is found in patients with poor baseline health status, which is the essential reason for its high mortality.

Abstract
BACKGROUND Spinal epidural abscess (SEA) is a rare but serious infection in the epidural space along the spinal cord. SEA should be considered in patients with backache, fever, neurological deficits and/or spinal tenderness. Early diagnosis is imperative to prevent permanent neurological sequelae. CASE DESCRIPTION We report a case of lumbar SEA in a 13-year-old girl who was immunocompetent and presented with spinal tenderness, back pain and 4 days of fever. A lumbar magnetic resonance imaging demonstrated an epidural abscess from L3-S1. She had emergent surgical intervention. Cultures grew methicillin-susceptible Staphylococcus aureus. She was also given long-term systemic antibiotics and she made a complete recovery within 2 months. CONCLUSIONS SEA in an immunocompetent pediatric without risk factors is an extremely rare condition. In the English-language literature, there are only 30 reported cases in the past 19 years; our case brings the total to 31. Non-surgical treatment has been successful in both adult and pediatric patients under certain conditions. Still, there exists a risk of deterioration with non-surgical management, even in patients for whom treatment is begun in the absence of neurologic deficits. Tracking neurological deficits in children can be challenging, particularly in young children who are non-verbal and not yet ambulating, and a reliable neurologic examination is a critical component of non-surgical care. In consideration of these facts and the accelerated time frame of deterioration, once neurologic deficits are present, surgery plus systemic antibiotics remains the standard of care for pediatric SEA patients, with each individual case meriting review of the full clinical picture.

Fotaki A, Anatoliotaki M, Tritou I, Tzagaraki A, Kampitaki M, Vlachaki G. Review and case report demonstrate that spontaneous spinal epidural abscesses are rare but dangerous in childhood. Acta Paediatr 2019; 108:28-36. [PMID: 30222897 DOI: 10.1111/apa.14579] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2018] [Revised: 07/03/2018] [Accepted: 09/12/2018] [Indexed: 01/27/2023]
Abstract
AIM A spinal epidural abscess (SEA) is a rare paediatric bacterial infection, with possible devastating neurological sequelae. We explored localisation in the cervical segment, which is unusual, but more dangerous, than other SEAs. METHODS We describe 22 cases (12 male) of paediatric SEAs without risk factors: 21 from a literature search from 2000 to 2017 and a 30-month-old boy with a spontaneous cervical SEA due to Group A Streptococcus. RESULTS The average age was eight years and the symptoms were mainly fever, back pain and motor deficit, with an aetiological diagnosis in 68%. Methicillin-sensitive Staphylococcus aureus was isolated in six patients, methicillin-resistant Staphylococcus aureus in two, Staphylococcus aureus with unknown susceptibility patterns in three and Group A Streptococcus in four. All patients underwent gadolinium-enhanced magnetic resonance imaging and most abscesses were localised in the thoracic and lumbar areas. More than half (59%) underwent surgery to remove pus and granulation tissue and nine were just treated with antimicrobial therapy for an average of 5.3 weeks. Most patients had good outcomes. CONCLUSION SEAs were underestimated in children due to the rarity and spectrum of differential diagnoses. Timely diagnosis, immediate antibiotics, spinal magnetic resonance imaging and prompt neurosurgical consultations were essential for favourable outcomes.

Abstract
Background Here we report a rare case of lumbar spine epidural abscess and facet joint septic arthritis caused by Streptococcus agalactiae, which had spread to the iliopsoas muscles, leading to urine retention. Case presentation A 68-year-old woman with low back pain experienced a sudden onset of bilateral lower limb weakness, it was followed 14 days later by urine retention. At consultation, magnetic resonance imaging and identification of serum β-hemolytic streptococci provided a diagnosis of Streptococcus agalactiae infection. She was started on antibiotics. Despite diminishing signs of inflammation, preoperative MRI showed an epidural mass at T12-L4 compressing the cord and involving the paravertebral muscles as well. Group B beta-hemolytic streptococci were detected in both urine and blood. Because of bilateral lower limb weakness and urine retention, T12-L4 hemilaminectomy was performed. The L3/L4 intertransverse ligament resected and abscess drained. Histopathology revealed that inflammatory cells had invaded the facet joint. Group B beta-hemolytic streptococci were identified, confirming the diagnosis. The patient continued with the antibiotics postoperatively, and her health rapidly improved. Conclusion Lumbar spine epidural abscess and facet joint septic arthritis caused by Streptococcus agalactiae is a clinical emergency, with significant morbidity and mortality especially with delayed diagnosis. A delay in both diagnosis and aggressive treatment can lead to not only severe neurological deficit but also to septicaemia, multiorgan failure, and even death.

Abstract
Spinal epidural abscess is rare in children. Early recognition is important to prevent or minimise neurological complications. We report a case of paediatric spinal epidural abscess. An 8-year-old girl, with a history of poorly controlled atopic eczema over the back of neck, presented with back pain and subsequently fever and worsening backache. Diagnosis was made only after computed tomography. Emergency operation with drainage of the abscess was done and vancomycin was given for 5 weeks. The patient made an uneventful recovery with no neurological complications. Bacteraemia from skin excoriation due to chronic eczema was the presumed aetiology.

Abstract
BACKGROUND Central nervous system (CNS) infections caused by Staphylococcus aureus are uncommon in pediatric patients. We review the epidemiology, clinical features and treatment in 68 patients with a S. aureus CNS infection evaluated at Texas Children's Hospital. METHODS Cases of CNS infection in children with positive cerebrospinal fluid cultures or spinal epidural abscess (SEA) for S. aureus at Texas Children's Hospital from 2001 to 2013 were reviewed. RESULTS Seventy cases of S. aureus CNS infection occurred in 68 patients. Forty-nine cases (70%) were secondary to a CNS device, 5 (7.1%) were postoperative meningitis, 9 (12.8%) were hematogenous meningitis and 7 (10%) were SEAs. Forty-seven (67.2%) were caused by methicillin-sensitive S. aureus (MSSA) and 23 (32.8%) by methicillin-resistant S. aureus (MRSA). Community-acquired infections were more often caused by MRSA that was clone USA300/pvl. Most patients were treated with nafcillin (MSSA) or vancomycin (MRSA) with or without rifampin. Among patients with MRSA infection, 50% had a serum vancomycin trough obtained with the median level being 10.6 μg/mL (range: 5.4-15.7 μg/mL). Only 1 death was associated with S. aureus infection. CONCLUSIONS The epidemiology of invasive of S. aureus infections continues to evolve with MSSA accounting for most of the infections in this series. The majority of cases were associated with neurosurgical procedures; however, hematogenous S. aureus meningitis and SEA occurred as community-acquired infections in patients without predisposing factors. Patients with MRSA CNS infections had a favorable response to vancomycin, but the beneficial effect of combination therapy or targeting vancomycin trough concentrations of 15-20 μg/mL remains unclear.

Abstract
BACKGROUND Lemierre disease is a rare postanginal sepsis caused by the anaerobe Fusobacterium necrophorum. It is associated with a pharyngitis that progresses quickly to thrombophlebitis of the internal jugular vein and metastatic abscesses to pulmonary, soft tissue, articular, and organ systems. It is rarely associated with spinal epidural abscesses. Because of the increasing antibiotic resistance, its incidence is on the rise. METHODS A single-patient case report of an adolescent male who initially presented to our institution for bacteremia and febrile episodes. Over a 1-week course, he developed severe back pain and progressive lower extremity weakness. Advanced imaging revealed an epidural abscess spanning T2-L3 level with extension into the psoas and the paraspinal musculature. Acute management consisted of broad-spectrum intravenous (IV) antibiotics and hemilaminectomy decompression from T2 to L3. The patient completed a 6-week course of IV antibiotics and was followed for a 1-year time period with close clinical follow-up. RESULTS Blood cultures identified the infecting organism as F. necrophorum. The combination of IV antibiotics and acute hemilaminectomy decompression resulted in successful clearance of the infecting organism with normalization of inflammatory markers and cultures. The patient noted immediate and sustained neurological improvement, with return of full motor and sensory function. At the 1-year timepoint, the patient was able to return to sports and no sagittal/coronal imbalance was noted on radiographs. CONCLUSIONS An aggressive case of Lemierre disease with extensive epidural abscess formation and neurological weakness was successfully managed with the combination of IV antibiotics and extensive hemilaminectomies for decompression. The patient exhibited no long-term sequela as a result of either the epidural abscess or of its treatment. LEVEL OF EVIDENCE Level V.

Abstract
Spinal infections are uncommon but significant causes of morbidity and hospitalization in the paediatric population. These infections encompass a broad range of conditions, from discitis to osteomyelitis and spinal epidural and intramedullary abscesses. Paediatric spinal infections can be caused by a range of bacterial, viral, fungal and parasitic agents. Ultrastructural differences of the vertebrae and associated structures result in distinct mechanisms of pathogenesis of spinal infections in children compared to adults. The non-specific nature of symptoms produced by them can cause considerable diagnostic delays. Magnetic Resonance (MR) imaging can facilitate early identification of the disease, and distinguish it from other spinal pathologies. The association of antimicrobial resistant bacterial strains from some of the cases appears worrisome; as is the increasing incidence of Kingella kingae infections causing spinal infections. Rest and immobilization are the general treatment, and prompt initiation of antimicrobial therapy is warranted to ensure optimal clinical outcome. Most patients generally have a good prognosis; however, early identification and prompt initiation of antimicrobial therapy is essential to achieve the best therapeutic response.

Abstract
MR imaging plays an important role in the detection and characterization of several pediatric disease entities that can occur in the emergent setting because of its cross-sectional imaging capability, lack of ionizing radiation exposure, and superior soft tissue contrast. In the age of as low as reasonably achievable, these advantages have made MR imaging an increasingly preferred modality for diagnostic evaluations even in time-sensitive settings. In this article, the authors discuss the current indications, techniques, and clinical applications of MR imaging in the evaluation of pediatric emergencies.

Abstract
A 34-day-old previously healthy boy born full term presented to the emergency department with fever at home (38.1°C), fussiness, and decreased oral intake for 1 day. He was difficult to console at home. He had decreased oral intake without emesis, diarrhea, or a change in urine output. He did not have rhinorrhea, cough, or increased work of breathing noted by parents. He lived at home with his parents and 13-year-old brother, did not attend day care, and had no sick contacts. On examination, he was fussy but consolable. He was febrile to 39.3°C, tachycardic (180 beats per minute), and tachypneic (64 breaths per minute), with mottling and a capillary refill of 3 seconds. The remainder of his examination was normal, without an infectious focus for his fever. A complete blood cell count with differential revealed leukocytosis. A basic metabolic panel was normal. A catheter urinalysis was normal. Cerebrospinal fluid examination yielded pleocytosis, low glucose, and elevated protein. Blood cultures were persistently positive with methicillin-sensitive Staphylococcus aureus, but cerebrospinal fluid cultures remained negative. We present his case, management, and ultimate diagnosis.

Abstract
Spinal epidural abscesses (SEAs) are unusual bacterial infections, with possible devastating neurologic sequelae. Despite abundance of case series in adults, reports in children are scanty. We describe a spontaneous SEA due to methicillin susceptible Staphylococcus aureus (MSSA) in a previously healthy 15-year old male, and we perform a literature review regarding management of pediatric SEAs without risk factors, from 2001 to 2014. We found a total of 12 cases (8 males, average age 9.6 years). Clinical presentation was mainly fever, back pain and elevation of inflammation markers. All cases were initially misdiagnosed. Lumbar puncture was performed in 36% of patients. Etiological diagnosis was obtained in 8 cases. MSSA was isolated in 4 patients, methicillin-resistant S. aureus in 1 patient, and S. aureus with unknown susceptibility patterns in 2 cases. The average of therapy duration was 6 weeks. Patients’ spine was always evaluated by gadolinium-enhanced magnetic resonance imaging; most abscesses were localized at thoracic and lumbar area, without osteomyelitis. In 8 cases, laminectomy and/or abscess drainage were performed in association with medical therapy; 3 cases were successfully treated with antimicrobial therapy only; no data were available in one case. A good outcome was obtained in all patients, except a reported residual headache and paraspinal pain lasting for 3 years. The rarity and the possible differential diagnosis can lead to underestimate SEA occurrence in children without risk factors. It seems therefore essential to maintain a high attention to pediatric SEAs. A prompt diagnosis and adequate therapy are essential prognostic factors for remission.

Abstract
STUDY DESIGN Review of the literature. OBJECTIVE To retrospectively examine the frequency of published fungal infections by species and the treatment algorithms used to eradicate the disease. SUMMARY OF BACKGROUND DATA Fungal infections of the spine present unique challenges to the modern multispecialty treatment team. Although rare in comparison with bacterial infections, fungal infections have been increasing in incidence over the past several decades. Evidences-based practice is limited to referencing smaller case series. METHODS MEDLINE, Scopus, and EMBASE searches were carried out by one of the authors as well as by the research desk at the University of Miami/Calder Memorial Library. We included peer-reviewed articles published between 1948 and September 2010; case reports, series, and reviews were all examined and compiled into a database. RESULTS A total of 130 articles, representing 157 cases, were included in the review. Aspergillus (60 cases, 38.2% of the total) and Candida species (36 cases, 22.9% of the total) were the 2 most common organisms. Surgery was associated with a greater survival rate than medical management alone in patients with Aspergillus (26.9% mortality in surgical patients; 60% in medically treated patients) and Candida (0% vs. 28.6%). Overall mortality was 19.3%. The overall recurrence rate was 7.4%. Amphotericin use was associated with a higher mortality rate than azoles. CONCLUSION Aspergillus is the most common published pathogen in fungal infections of the spine. Recent publications depicting the use of newer antifungal medications such as azoles report higher survival rates. Surgically treated patients in combination with antifungal therapy showed highest frequencies of patient survival in Aspergillus and Candida infections. LEVEL OF EVIDENCE 3.

Abstract
Spinal infections represent a group of rare conditions affecting vertebral bodies, intervertebral discs, paraspinal soft tissues, epidural space, meninges, and spinal cord. The causal factors, clinical presentations, and imaging features are a challenge because the difficulty to differentiate them from other conditions, such as degenerative and inflammatory disorders and spinal neoplasm. They require early recognition because delay diagnosis, imaging, and intervention may have devastating consequences especially in children and the elderly. This article reviews the most common spinal infections, their pathophysiologic, clinical manifestation, and their imaging findings.

Abstract
INTRODUCTION Spinal epidural abscess (SEA) is a very rare condition in pediatric patients. Varicella zoster infection could be a predisposing factor, and SEA should be suspected in patients with signs of secondary bacterial infection and even mild neurological signs. CLINICAL CASE We describe here a case of a 30-month-old girl with a history of remitting varicella infection, diagnosed for a lumbar epidural abscess and sacro-ileitis, secondary to group A Streptococcus (GAS). DISCUSSION This is the third case of SEA from GAS reported in the literature in a pediatric population with varicella infection. We discuss here the clinical presentation and the diagnostic challenges for SEA in childhood through a review of the literature.

Abstract
Spinal epidural abscess (SEA) is a rare condition that requires prompt diagnosis and initiation of treatment for optimal outcome. Treatment generally consists of surgical intervention and systemic antibiotics. We present 1 of the largest cohorts of nontuberculous pediatric SEA in the English literature, emphasizing the outcomes of conservative (ie, nonoperative) management. We retrospectively identified 9 pediatric patients (≤18 years of age) with SEAs at Our Lady of the Lake Children's Hospital from 2002 to 2011. Cases were reviewed for demographic, clinical, diagnostic, and treatment characteristics and outcomes. The diagnosis of SEA was made by MRI in all cases, and methicillin-resistant Staphylococcus aureus (MRSA) was the only identified pathogen, isolated via blood culture in 6 of 9 patients. Although every patient received systemic antibiotics, only 2 had neurosurgical intervention. Four of the 7 patients treated conservatively received computed tomography-guided needle drainage. All patients recovered without significant sequelae. SEA is a potentially fatal illness that necessitates a heightened clinical awareness for diagnosis and treatment. Although official recommendations regarding management in pediatrics are lacking, treatment has generally been surgical decompression and drainage in combination with antibiotics; recent reports have suggested that antibiotic therapy alone may be successful in select patient populations. Although the adult literature has suggested that such management can be trialed in specific situations, only a handful of cases in the pediatric literature have reported this nonoperative approach. We present one of the largest reviews in support of successfully treating SEA with nonsurgical therapy.

Spinal epidural abscess (SEA) is a rare clinical condition among children. Most patients do not present with classical signs. A 13-year-old boy without any predisposing factors presented with paraparesis, bladder and bowel involvement. MRI spine demonstrated an SEA at the C7 and D1 levels on both sides of the midline with cord oedema at the C2-3 to C6 level with minimal marrow oedema in the C6 vertebral body. We treated the patient with antibiotics (ceftriaxone and vancomycin) alone. The patient showed excellent response with only minimal residual gait disturbance at the end of 6 weeks of antibiotic therapy. This is the first paediatric report of complete recovery of a patient at clinical stage 4 following antibiotic treatment alone from India. However, caution should be exercised to closely monitor the patient's recovery as any progression in the neurological state warrants surgery.

Abstract
Vertebral osteomyelitis caused by Aspergillus nidulans is rare and usually affects immunocompromised patients. This report presents a case of thoracic vertebral osteomyelitis with epidural abscesses due to A. nidulans in a 40-year-old immunocompetent female who presented with back pain, numbness and weakness of both lower limbs. Magnetic resonance imaging demonstrated osteomyelitis involving the thoracic (T)1-T3 vertebral bodies with epidural abscesses, resulting in spinal compression. The patient underwent a decompression laminectomy of T1-T3 and debridement of the thoracic epidural inflammatory granuloma. Histopathology revealed fungal granulomatous inflammation. The patient received 6 mg/kg voriconazole every 12 h (loading dose on day 1) followed by 4 mg/kg voriconazole twice daily for 1 month, administered intravenously. The patient returned with recurrent back pain 16 months after initial presentation. A. nidulans was identified by fungal culture and polymerase chain reaction. The patient showed no evidence of recurrence 1 year after a 6-month course of oral voriconazole. The key to the effective treatment of Aspergillus osteomyelitis is not to excise the abscess, but to administer systemic antifungal drug therapy.

Abstract
BACKGROUND In recent years, multiresistant Pasteurella multocida isolates from bovine respiratory tract infections have been identified. These isolates have exhibited resistance to most classes of antimicrobial agents commonly used in veterinary medicine, the genetic basis of which, however, is largely unknown. METHODS Genomic DNA of a representative P. multocida isolate was subjected to whole genome sequencing. Genes have been predicted by the YACOP program, compared with the SWISSProt/EMBL databases and manually curated using the annotation software ERGO. Susceptibility testing was performed by broth microdilution according to CLSI recommendations. RESULTS The analysis of one representative P. multocida isolate identified an 82 kb integrative and conjugative element (ICE) integrated into the chromosomal DNA. This ICE, designated ICEPmu1, harboured 11 resistance genes, which confer resistance to streptomycin/spectinomycin (aadA25), streptomycin (strA and strB), gentamicin (aadB), kanamycin/neomycin (aphA1), tetracycline [tetR-tet(H)], chloramphenicol/florfenicol (floR), sulphonamides (sul2), tilmicosin/clindamycin [erm(42)] or tilmicosin/tulathromycin [msr(E)-mph(E)]. In addition, a complete bla(OXA-2) gene was detected, which, however, appeared to be functionally inactive in P. multocida. These resistance genes were organized in two regions of approximately 15.7 and 9.8 kb. Based on the sequences obtained, it is likely that plasmids, gene cassettes and insertion sequences have played a role in the development of the two resistance gene regions within this ICE. CONCLUSIONS The observation that 12 resistance genes, organized in two resistance gene regions, represent part of an ICE in P. multocida underlines the risk of simultaneous acquisition of multiple resistance genes via a single horizontal gene transfer event.

Abstract
Spinal epidural abscess (SEA) is a rare infection associated with well-established risk factors mainly in adults. We describe an 11-year-old girl without any known risk factors who presented with fever and localized spinal tenderness in the lumbar area and was diagnosed with spinal MRI as suffering from a posterior SEA extending between T11 and L4. She was successfully managed with sequential intravenous and oral antibiotics along with minimally invasive surgery without laminectomy. Methicillin-sensitive Staphylococcus aureus was the responsible pathogen isolated at surgery. Immediate institution of antibiotics, spinal MRI, and well-timed neurosurgical consultation are mandatory for a favorable outcome in cases of SEA in children.

Abstract
Spinal epidural abscess (SEA) is a rare disease in children without predisposing risk factors. Atypical presentations of SEA without the classic triad of fever, back pain, and neurological signs, have previously been described. We report an atypical presentation of an acute SEA in a previously healthy adolescent female. This 15-year-old patient presented with right shoulder pain in the absence of the fever, back pain, or long-tract signs; therefore, the diagnosis of the spinal pathology was delayed. Eventually, a thoracic SEA was identified by gadolinium-enhanced magnetic resonance imaging and treated with surgical decompression followed by intravenously administered antibiotics. The patient's course was complicated by chronic headache. Our experience adds to the literature a case that demonstrates the difficulty in diagnosis of atypical presentations of SEA in previously healthy children. In addition, referred or autonomically mediated pain should be considered in unusual pain presentations. Children with significant extremity or abdominal pain should be considered for the possibility of sympathetically mediated pain syndrome due to a thoracic-level spinal cord lesion such as a SEA.

Abstract
BACKGROUND Spinal epidural abscess (SEA) in children is a rare infectious emergency warranting prompt intervention. Predisposing factors include immunosuppression, spinal procedures, and local site infections such as vertebral osteomyelitis and paraspinal abscess. Staphylococcus aureus is the most common isolate. DESIGN Case report and literature review. FINDINGS A 2.5-year-old boy with tetraparesis was found to have an SEA in the posterior lumbar epidural space with evidence of meningitis and myelitis on MRI spine in the absence of any local or systemic predisposing factors or spinal procedures. Streptococcus pneumoniae was isolated from the evacuated pus. CONCLUSIONS Definitive treatment of SEA is a combination of surgical decompression and iv antibiotics. Timely management limits the extent of neurological deficit.

Abstract
Immunocompromised patients are at high risk of secondary infection associated with high morbidity. In children these complications include fungal osteomyelitis due to continuous infiltration or hematogenous spread. The case of a 4-year-old boy is presented who developed lumbalgia and thigh pain during ongoing chemotherapy for acute lymphatic leukemia. MRI revealed infarct-like lesions in the femur and L5 vertebra, which were biopsied. The histologic diagnosis was consistent with angioinvasive aspergillosis. A multifocal osseous presentation has rarely been described in children and an overview of the literature is presented. Invasive aspergillosis is a rare complication to be considered in children with MRI-detected bony lesions of infarct-like appearance.

Abstract
Spinal epidural abscess is rare in infants and leads to major permanent neurological deficits if the condition is left untreated. Holocord epidural abscess is extremely rare. We report a patient with methicillin-resistant Staphylococcus aureus septicemia presenting with pneumonia, retroperitoneal abscess, and epidural abscess. A 7-month-old previously healthy girl presented with fever, irritability, tachypnea for 4 days and decreased movement of the right lower limb for 1 day. Magnetic resonance imaging of the spine demonstrated an extensive epidural abscess from second cervical to fifth lumbar vertebrae without osteomyelitis or discitis. The epidural abscess was treated with intravenous antibiotics for 6 weeks. At 3 months follow-up, no neurological deficits were present. Only a few case reports of holocord epidural abscess in children have been published. We present a case of conservatively treated holocord spinal abscess in an infant.

Abstract
Invasive aspergillosis is rare in immunocompetent people but contributes to significant morbidity and mortality in immunosuppressed patients. The majority (approximately 80%) of invasive Aspergillus infections is caused by Aspergillus fumigatus. The second most frequent (approximately 15-20%) pathogenic species is Aspergillus flavus and to a lesser extent, Aspergillus niger and Aspergillus terreus. Aspergillus flavus has emerged as a predominant pathogen in patients with fungal sinusitis and fungal keratitis in several institutions worldwide. To date, there has not been any publication exclusively reviewing the topic of A. flavus in the literature. This article reviews the microbiology, toxigenicity and epidemiology of A. flavus as well as describes the clinical characteristics, diagnosis and management of infections caused by this organism.

Abstract
BACKGROUND Appropriate anesthesia for pediatric renal transplantation requires stable intraoperative hemodynamics, optimal perfusion of the newly transplanted kidney and good analgesia during recovery. The aim of this study was to assess the preliminary application, success and safety of combined epidural and general anesthesia in pediatric renal transplantation in a small cohort. METHODS We retrospectively reviewed the anesthesia records of 46 consecutive pediatric patients who received renal transplantation under combined epidural and general anesthesia from January 2003-2007. RESULTS The mean patient age and weight were 13.2 +/- 2.4 years and 25.7 +/- 5.46 kg, respectively. The infused crystalloids, 20% albumin and red blood cell concentrates were 120 +/- 2 mL/kg to achieve a CVP of 13 to 15 mm Hg. Brisk diuresis was observed in all patients. Epidural tramadol (2 mg/kg) provided good postoperative analgesia in 89% patients. 15% patients developed radiological evidence of pulmonary edema, only one required mechanical ventilation for hypoxemia. Minor adverse effects were nausea and vomiting (17.5%) and convulsions (8.5%). No perioperative mortality or major morbidity was recorded. CONCLUSION Epidural anesthesia is a useful adjunct to general anesthesia due to stable intraoperative haemodynamics and good postoperative analgesia.

Abstract
Aspergillus flavus is the second most common Aspergillus spp. causing invasive infections in immunocompromised patients. Extensive prophylactic use of voriconazole (VCZ) in immunocompromised patients may enhance the selection of VCZ-resistant clinical isolates of A. flavus, compromising the effectiveness of this antifungal drug against A. flavus infection. To study triazole resistance, we selected A. flavus isolates in the laboratory showing reduced in vitro susceptibility to VCZ. The cyp51A and cyp51B genes coding for P450 14alpha-sterol demethylases A (CYP51Ap) and B (CYP51Bp) were characterised to examine possible drug target modification-dependent resistance to VCZ in this fungus. High-molecular-weight DNA was isolated from 10 A. flavus isolates showing in vitro resistance to VCZ (minimum inhibitory concentration (MIC) range 4-32 microg/mL) as well as from the drug-susceptible parent isolate X26728 (MIC = 1 microg/mL). The cyp51A and cyp51B genes were cloned and the nucleotide sequences were determined. A comparison of the deduced amino acid sequences of CYP51Ap from 10 VCZ-resistant isolates with that of the drug-susceptible parent showed no amino acid variation in six of the ten isolates. CYP51Ap from isolates Afl-VCZ6 and Afl-VCZ46 showed a K197N change, CYP51Ap from isolate Afl-VCZ114 showed Y132N and T469S changes, whereas that from isolate Afl-VCZ45 showed K197N, D282E and M288L changes. These results suggest that VCZ-resistant A. flavus isolates can be readily isolated in the laboratory under selection pressure. Multiple mechanisms, including drug target modification, may be responsible for the in vitro resistance of A. flavus to VCZ.

Abstract
OBJECTIVE To describe a spinal epidural abscess that originated from cellulitis after moxibustion. METHODS Case report. FINDINGS A 78-year-old woman with diabetes mellitus was diagnosed with tetraplegia due to a cervical spinal epidural abscess extending to the thoracic spinal epidural space. The abscess was caused by osteomyelitis and cellulitis of the right third finger, which had been cauterized repeatedly with moxa. After surgical decompression and drainage of the spinal epidural abscess and comprehensive rehabilitation, motor strength and functional level improved. CONCLUSIONS This case illustrates the risk of spinal epidural abscess in persons with diabetes mellitus who present with focal cellulitis and osteomyelitis.

Abstract
Spondylodiscitis is an unusual diagnosis among children and consequent abscess formation is even rarer. A 6-year-old girl with fever, hip pain, and refusal to walk was evaluated. The neurologic examination was normal. Recurrent joint pain with cold weather, iron for anemia without improvement, and decreased intervertebral spaces raised the use of ceftriaxone, oxacillin, and external immobilization. Hemoglobin sickle cell disease, spondylodiscitis with paravertebral collections, and epidural abscess were documented. She was fully recovered. The treatment was conservative because there was no neurologic deficit. We add to the literature 1 case of spondylodiscitis with epidural abscess that was successfully treated with antibiotics alone.
