Abstract
Description Spinal epidural abscess (SEA), a critical surgical emergency, demands prompt recognition and intervention to prevent severe complications and fatalities. The incidence of SEA is notably increasing, particularly among individuals with diabetes, intravenous drug use, or a history of invasive spinal procedures. Although SEA can manifest through various clinical symptoms, the presence of its classic triad-back pain, fever, and neurological deficits-is noteworthy despite its occurrence in only 10% to 13% of cases. Identifying this triad is vital due to its high specificity for SEA, which is essential to guiding swift diagnostic and therapeutic actions in a condition where early intervention is critical. Magnetic resonance imaging is pivotal in diagnosing SEA, offering unmatched sensitivity and specificity compared to other imaging techniques. Immediate empirical antibiotic therapy and timely neurosurgical consultation, when required, form the foundation of SEA treatment. The prognosis significantly depends on the patient's initial neurological status, underlying health conditions, and the timeliness of their presentation, diagnosis, and treatment initiation. Given the complexity of SEA and the high risk of diagnostic delays, managing this condition involves substantial medicolegal considerations. Enhanced comprehension of SEA is imperative for improving patient outcomes and reducing health care resource burdens. Prompt and accurate diagnosis and appropriate interventions are essential for effectively managing this urgent condition.

Abstract
Introduction Multiple spinal epidual abscesses with multifocal systemic abscess and multiple joint septic arthritis present with a large infective burden resulting in sepsis, systemic inflammatory dysregulation, and multi-organ failure. This requires pre-operative resuscitation and surgery of greater complexity, longer operative duration, and blood loss, creating challenges to surgical management. Case Report A 69-year-old Chinese female presented with multilevel discrete spinal epidural abscesses along the cervical, thoracic, and lumbar spine, alongside concomitant multifocal systemic abscesses and multiple small joint septic arthritis. She received pre-operative resuscitation to restore organ function, reverse acidosis, and coagulopathy, prior tobefore surgical decompression of selected abscesses and joints under a multidisciplinary team. Remaining sites of infection without significant compression were undrained. The patient recovered well with no residual neurological deficits. Conclusion Multifocal infections in critically ill patients require a multidisciplinary team for preoperative resuscitation, joint surgical planning, and prioritiszing surgical interventions to prevent excessive surgical stress to the patient.

Abstract
Background Extensive spinal epidural abscess (SEA) is an exceptional and threatening condition that requires prompt recognition and proper management to avoid potentially disastrous complications. We aimed to find key elements of early diagnosis and rational treatments for extensive SEA. Case presentation A 70-year-old man complained of intense pain in the cervical-thoracic-lumbar spine that radiated to the lower extremity. Laboratory test results revealed a marked increase in all indicators of infection. The spinal magnetic resonance imaging (MRI) revealed a ventral SEA extending from C2 to L4. Owing to the patient's critical condition, laminectomy, drainage, and systemic antibiotic therapy were administered. And the multidrug-resistant Staphylococcus epidermidis was detected in the purulent material from this abscess. Results Postoperative MRI revealed diminished epidural abscess, and the clinical symptoms were dramatically and gradually relieved after two rounds of surgery and systemic antibiotic therapy involving the combination of ceftriaxone, linezolid, and rifampicin. Conclusions A comprehensive emergency assessment based on neck or back pain, neurological dysfunctions, signs of systemic infection, and MRI are important for early diagnosis of extensive SEA. Further, the combination of laminectomy, drainage, and systemic antibiotic therapy may be a rational treatment choice for patients with SEA, especially for extensive abscess or progressive neurological dysfunction.

Abstract
Spinal epidural empyema (SEE) represents a neurological emergency in veterinary medicine, but information on this condition is limited to date. This retrospective case series study describes the clinical and magnetic resonance imaging (MRI) features, and the outcome of conservative or surgical management of SEE in 30 dogs diagnosed with SEE from September 2015 to March 2020 at one referral neurology centre. The most frequent clinical sign was pain 28/30 (93%), and 22/30 (73%) showed neurological signs with ambulatory paraparesis/tetraparesis 15/30 (50%), monoparesis 1/30 (3.3%), non-ambulatory paraparesis 3/30 (10%), or paraplegia 3/30 (10%). MRI was valuable for the diagnosis and in the follow-up. In this group of dogs, 24/30 (80%) were conservatively treated and 6/30 (20%) were surgically treated. The outcome was considered favourable in all dogs: 20/30 (66.6%) achieved full recovery (3 surgically treated and 17 medically treated) and 10/30 (33.3%) dogs had an improvement in the neurological signs with residual ambulatory paresis (3 surgically treated and 7 medically treated). Surgical treatment showed better short-term (7 days) outcomes than medical treatment in non-ambulatory paraparetic or paraplegic dogs (33%). Nevertheless, this study suggests that a good recovery may be achieved with conservative treatment even for non-ambulatory or paraplegic dogs. Further prospective studies, with a standardised protocol of diagnostic tests and a homogeneous distribution of conservatively and surgically treated dogs, are needed to establish treatment guidelines.

Abstract
Background: Therapeutic epidural spinal injections (ESIs) of steroids are one of the most common nonsurgical management modalities employed for alleviating pain due to chronic persistent lumbar spinal disease. However, it is well documented that they have significant risks and complications without any long-term efficacy. ESI may result in epidural empyema which may be difficult to diagnose with delays resulting in significant permanent neurological sequelae. Case Description: A 45-year-old female presented with a lumbar spinal epidural empyema after receiving ESI for low back and right leg pain due to a lumbar disc herniation. Laboratory studies showed elevations of multiple inflammatory markers, and the MR documented a significant lumbar epidural empyema contributing to significant thecal sac compression. Clinically, the patient had an acute cauda equina syndrome warranting emergency surgery consisting of a laminectomy for debridement/decompression followed by long-term antibiotic treatment. Conclusion: Epidural empyema is a major potential complication of lumbar ESI. Multiple markedly elevated inflammatory markers (WBC, ESR, CRP, and procalcitonin) and MRI evidence of an epidural empyema necessitates emergent surgical intervention to limit morbidity, neurological sequelae, and mortality.

Abstract
This case series reviews previous publications and reports four feline spinal epidural empyema cases that presented with non-ambulatory thoracolumbar myelopathy. Two cats underwent myelography and two MRI. Bacteria were obtained in three cases, in two from epidural abscesses and from a tail base wound in one; histopathological examination of epidural tissue showed pyogranulomatous changes in the remaining cat. Three cats were treated by surgical decompression plus antimicrobial therapy and one cat was treated medically. All cats showed satisfactory improvement following treatment over a follow-up period of 3 months. Spinal epidural empyema is a rare condition but all cats in this series had favourable outcomes.

Abstract
CASE DESCRIPTION 5 dogs were examined because of clinical signs of myelopathy, including signs of pain associated with the spinal region and rapidly progressive neurologic deficits. CLINICAL FINDINGS In all dogs, results of MRI were consistent with spinal epidural empyema. Concurrent infectious processes were identified at adjacent or distant sites in all dogs, including diskospondylitis, prostatitis, dermatitis, paraspinal infection following a penetrating injury, urinary tract infection, and pyothorax. Bacteria were isolated from 3 dogs; Escherichia coli was isolated from blood, urine, and prostatic wash samples from 1 dog; a Pasteurella sp was isolated from a percutaneous aspirate from an adjacent infected wound in a second dog; and a Corynebacterium sp was isolated from a thoracic fluid sample from a third dog. For the remaining 2 dogs, results of bacterial culture were negative. TREATMENT AND OUTCOME All dogs showed clinical improvement within 2 weeks after initiation of antimicrobial treatment, and all had an excellent long-term outcome. CLINICAL RELEVANCE In dogs, spinal epidural empyema has previously been regarded as a surgical emergency. Findings for dogs in the present report suggested that, as is the case for humans, selected dogs with spinal epidural empyema may be successfully managed with medical treatment alone.

Abstract
Intraspinal abscesses (ISAs) are rare lesions that are often neurologically devastating. Current treatment paradigms vary widely including early surgical decompression, drainage, and systemic antibiotics, delayed surgery, and sole medical management. The National Inpatient Sample (NIS) database was queried for cases of ISA from 2003 to 2012. Early and late surgery were defined as occurring before or after 48h of admission. Outcome measures included mortality, incidence of major complications, length of stay (LOS), and inpatient costs. A total of 10,150 patients were included (6281 early surgery, 3167 delayed surgery, 702 medical management). Paralysis, the main comorbidity, was most associated with early surgery (p<0.0001). In multivariate analysis, the rates of postoperative infection and paraplegia were highest with early surgery (p<0.0001), but the incidence of sepsis was higher with delayed surgery (p<0.0001). Early surgery was least associated with in-hospital mortality (p=0.0212), sepsis (p<0.001), and had the shortest LOS (p<0.001). Charges were highest with delayed surgery, and least with medical management (p<0.001). Medical management was associated with lower rates of complications (p<0.001). This is the largest study of patients with ISAs ever performed. Our results suggest that patients with ISAs undergoing surgical management have better outcomes and lower costs when operated on within 48h of admission, emphasizing the importance of accurate and early diagnosis of ISA.

Abstract
Spinal epidural abscess (SEA) is a rare but often devastating infection of the epidural space around the spinal cord. When an SEA is widespread, extensive decompression with laminectomy is often impossible, as it may subject the patient to very long operative times, extensive blood loss, and mechanical instability. A technique called "skip laminectomy" has been described in the literature, in which laminectomies are performed at the rostral and caudal ends of an abscess that spans 3-5 levels and a Fogarty catheter is used to mechanically drain the abscess, much like in an embolectomy. In this report of 2 patients, the authors present a modification of this technique, which they call "apical laminectomies" to allow for irrigation and drainage of an extensive SEA spanning the entire length of the vertebral column (C1-2 to L5-S1). Two patients presented with cervico-thoraco-lumbar SEA. Laminectomies were performed at the natural apices of the spine, namely, at the midcervical, midthoracic, and midlumbar spine levels. Next, a pediatric feeding tube was inserted in the epidural space from the thoracic laminectomies up toward the cervical laminectomy site and down toward the lumbar laminectomy site, and saline antibiotics were used to irrigate the SEA. Both patients underwent this procedure with no adverse effects. Their SEAs resolved both clinically and radiologically. Neither patient suffered from mechanical instability at 1 year after treatment. For patients who present with extensive SEAs, apical laminectomies seem to allow for surgical cure of the infectious burden and do not subject the patient to extended operating room time, an increased risk of blood loss, and the risk of mechanical instability.

Abstract
This case report describes a 63-year-old male patient with considerably impaired postoperative wound healing in the region of the lower extremities. After initial drug therapy for the pain was ineffectual, the patient was treated repeatedly through an epidural catheter. In the further course, an extensive spinal epidural abscess was diagnosed as an incidental finding without neurological symptoms. After taking into consideration the patient's age and the risk factors present as well as inclusion of the subspecialties involved for an interdisciplinary assessment, the patient was successfully treated with a conservative approach. Our contribution concludes with a detailed discussion and comparison of the literature.

Abstract
OBJECTIVE To characterize the clinical signs, diagnostic and surgical findings, and outcome in dogs with spinal epidural empyema (SEE). STUDY DESIGN Retrospective study. ANIMALS Seven dogs. METHODS Dogs with SEE between 1992 and 2001 were identified from a computerized medical record system. Inclusion criteria were: neurologic examination, vertebral column radiographs, myelography, antimicrobial culture and susceptibility of material collected surgically from the vertebral canal, a definitive diagnosis of SEE confirmed by surgery, and microscopic examination of tissue from the vertebral canal. RESULTS Common signs were lethargy, fever, anorexia, apparent spinal pain, and paraparesis/plegia. Common laboratory abnormalities were peripheral neutrophilia, and neutrophilic pleocytosis in cerebrospinal fluid (CSF). Three dogs had concurrent discospondylitis and 1 of these had vertebral luxation. On myelography, extradural spinal cord compression was focal (2 dogs), multifocal (3), or diffuse (2). Bacteria were isolated not from CSF but from blood, surgical site, pleural fluid, or urine in 6 dogs. Dogs were administered antibiotics and had surgical decompression by hemilaminectomy. Five dogs improved neurologically and had a good long-term outcome. Two dogs were euthanatized, 1 because of worsening of neurologic signs and pneumonia, and the other because of herniation of a cervical intervertebral disc 1 month postoperatively, unrelated to the SEE. CONCLUSION Dogs with SEE may have a good outcome when treated by surgical decompression and antibiotic administration. CLINICAL RELEVANCE SEE should be included in a list of possible causes for dogs with fever, apparent spinal pain, and myelopathy.

Abstract
Until recently epidural abscess was considered a rare, almost theoretical, complication of central nerve block, but anecdotal reports suggest that this is no longer the case. Thus a review of the risk factors, pathogenesis, clinical features and outcome of this condition is appropriate, the primary aim being to make recommendations on best anaesthetic practice to minimize the risk of this serious complication. A search of EMBASE(c), PUBMED(c) and MEDLINE(c) databases from 1966 to September 2004 was performed using several strategies, supplemented by reference list screening. Spontaneous epidural abscess is rare, accounting for 0.2-1.2 cases per 10,000 hospital admissions per year. Estimates of the incidence after central nerve block vary from 1:1,000 to 1:100,000. Risk factors (compromised immunity, spinal column disruption, source of infection) are present in the majority of patients, whether the condition is spontaneous or associated with central nerve block. Presentation is vague, fever and back pain usually preceding neurological deficit. Diagnosis requires a high index of suspicion and modern imaging techniques. Treatment involves early surgical drainage to prevent permanent deficit and high dose parenteral antibiotics chosen with bacteriological advice. Primary prevention depends on proper use of full aseptic precautions. Epidural abscess can be a catastrophic consequence of central nerve block. Early diagnosis will minimize permanent damage, but primary prevention should be the aim. There is a need for a large survey to indicate the true incidence to better inform the risk-benefit ratio for central nerve block.

Abstract
STUDY DESIGN A study correlating protein S-100b serum levels with postoperative functional outcome in patients with spinal cord compression resulting from epidural empyema. OBJECTIVES To evaluate the potential value of protein S-100b for prediction of individual functional outcome in medullary lesions resulting from spinal epidural empyema. SUMMARY OF BACKGROUND DATA Despite modern medical advances, a reliable individual prediction of functional outcome in case of spinal epidural empyema is still not possible. METHODS Forming two outcome groups, clinical outcome following surgery was considered to be favorable in case of neurologic improvement with preservation or retrieval of walking ability, whereas nonimprovement without restoration of gait function was regarded to be unfavorable. Venous blood samples for protein S-100b were taken from all patients immediately after admission and regularly after operative decompression. Initial levels of S-100b were correlated with preoperative degree and duration of paresis, and the individual time course of S-100b measurements was correlated with clinical outcome. RESULTS The initial level of protein S-100b is not correlated with preoperative degree and duration of paresis or with functional outcome. The individual time course of S-100b measurements, however, is different in both outcome groups. Levels of protein S-100b that were either always normal or that were initially increased but normalized rapidly within 3 days were invariably associated with retrieval of gait function, whereas none of those patients recovered in whom increased levels of S-100b persisted beyond the third postoperative day (P < 0.003). CONCLUSIONS Protein S-100b might be a promising serum marker with prognostic significance in the event of spinal cord compression resulting from epidural empyema.
