We present a case of a 94-year-old female who presented to the emergency room with a fever and generalized weakness without an initial obvious source of infection. Throughout admission, she continued to be febrile despite broad-spectrum antibiotics. Several days into admission, the patient complained of severe back pain, necessitating magnetic resonance imaging (MRI) of the entire spine. The imaging revealed an extensive epidural fluid collection consistent with a spinal epidural abscess. Fortunately, she did not have any neurological deficits and was treated conservatively with IV antibiotics with improvement. This case highlights this rare presentation and the importance of early diagnosis and management of spinal epidural abscesses.

A spinal epidural abscess is a rare condition characterized by the accumulation of pus between the dura mater and vertebral column, often caused by hematogenous spread from a distant site or local spread from infection in nearby structures. The abscess leads to compression of the spinal cord and can result in neurological damage, including dysfunction or permanent neurological deficits. Treatment of spinal epidural abscesses should not be delayed and requires a combination of decompression by surgical drainage and antibiotic therapy. The authors present a rare case in which a spinal epidural abscess developed from a hospital-acquired pressure ulcer, further complicated by bacteremia.

UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

Spinal epidural abscess (SEA) can lead to a subacute onset of neurological deficits of the extremities and is commonly accompanied by spondylodiscitis if located anterior to the dura. Lactococcus garviae is a fish pathogen that is occasionally found in poultry, cattle, and swine. It is a rare cause of infection in humans. Most commonly it is associated with endocarditis. Until 2019, less than 30 cases of human Lactoccous garviae infection have been published. To the best of our knowledge, we present the second reported case of SEA with spondylodiscitis caused by Lactococcus garviae. How Lactococcus garviae caused SEA, remains unclear in this case.

OBJECTIVE: There is limited consensus regarding management of spinal epidural abscesses (SEAs), particularly in patients without neurologic deficits. Several models have been created to predict failure of medical management in patients with SEA. We evaluate the external validity of 5 predictive models in an independent cohort of patients with SEA.
METHODS: One hundred seventy-six patients with SEA between 2010 and 2019 at our institution were identified, and variables relevant to each predictive model were collected. Published prediction models were used to assign probability of medical management failure to each patient. Predicted probabilities of medical failure and actual patient outcomes were used to create receiver operating characteristic (ROC) curves, with the area under the receiver operating characteristic curve used to quantify a model\'s discriminative ability. Calibration curves were plotted using predicted probabilities and actual outcomes. The Spiegelhalter z-test was used to determine adequate model calibration.
RESULTS: One model (Kim et al) demonstrated good discriminative ability and adequate model calibration in our cohort (ROC = 0.831, P value = 0.83). Parameters included in the model were age >65, diabetes, methicillin-resistant Staphylococcus aureus infection, and neurologic impairment. Four additional models did not perform well for discrimination or calibration metrics (Patel et al, ROC = 0.580, P ≤ 0.0001; Shah et al, ROC = 0.653, P ≤ 0.0001; Baum et al, ROC = 0.498, P ≤ 0.0001; Page et al, ROC = 0.534, P ≤ 0.0001).
CONCLUSIONS: Only 1 published predictive model demonstrated acceptable discrimination and calibration in our cohort, suggesting limited generalizability of the evaluated models. Multi-institutional data may facilitate the development of widely applicable models to predict medical management failure in patients with SEA.

OBJECTIVE: Thoracic spinal epidural abscess (SEA) is a rare but dangerous condition, and traditional surgical methods are accompanied by extensive trauma and approach-related complications. Here we introduce the technique of full-endoscopic transforaminal debridement and decompression and evaluate its feasibility for treating brucellar thoracic SEA.
METHODS: We performed thoracic full-endoscopic transforaminal decompression and debridement on two patients with neurological deficits caused by brucellar SEA, which is mainly composed of granulation tissue rather than pus. Postoperative MRI was conducted to confirm the presence of any residual abscess compressing the nerves. Frankel grading was employed to assess the recovery of neurological function, and complications were documented.
RESULTS: There were no occurrences of dural tear, postoperative hematoma, or pulmonary complications. Their neurological function had significantly improved after surgery, and postoperative MRI confirmed no residual abscess compressing the spinal cord. During the 2-year follow-up, one patient achieved complete recovery (from Frankel-C to Frankel-E), while another patient improved from Frankel-A to Frankel-D. Neither patient experienced infection recurrence, instability, nor kyphotic deformity.
CONCLUSIONS: We described the novel application of transforaminal endoscopic surgery in brucellar thoracic granulomatous SEA and preliminarily indicated the feasibility of this technique as a minimally invasive alternative to open surgery.

Background  Spinal epidural abscess is a rare but serious condition that can cause spinal cord compression and neurological deficits. Case Description and Methods  The article reports a case of a 31-year-old patient who presented with an infectious cellulitis in the left hand, which progressed to a spinal epidural abscess. The diagnosis was confirmed by clinical examination and magnetic resonance imaging. Treatment involved laminectomy, after which the patient had complete recovery of neurological deficits. This article is a case report with a literature review. Patient data and images were collected by the researchers who participated in the patient\'s care. The literature was reviewed by one of the researchers based on the search for articles in the PubMed database. For the research, the following keywords were inserted: \"Spinal epidural empyema,\" \"Spinal epidural abscess.\" Conclusion  Spinal epidural abscess is often underdiagnosed, which can lead to delays in treatment and serious complications. The relationship between cellulitis and spinal epidural abscess may be related to the spread of infection through the lymphatic or blood system.

BACKGROUND: Colorectal cancer is one of the most frequently diagnosed forms of cancer, and it is associated with several common symptoms and signs such as rectal bleeding, altered bowel habits, abdominal pain, anemia, and unintentional weight loss. Sciatica, a debilitating condition in which the patient experiences paresthesia and pain in the dermatome of associated lumbosacral nerve roots or sciatic nerve distribution, is not considered one of these. Here we present a case of colorectal cancer manifesting symptoms of sciatica alone.
METHODS: A 68-year-old male presented with progressive lower back pain radiating to his left thigh and calf over L5/S1 dermatome. Sciatica was suspected and initially underwent conservative treatment with analgesics. However, the symptoms progressed and MRI revealed an epidural abscess surprisingly. Surgical debridement was performed and pus culture isolated Streptococcus gallolyticus. Based on the strong association of S. gallolyticus with colorectal cancer, the presence of this pathogen prompted further tumor evaluation, even in the absence of the typical symptoms and signs. This investigation ultimately leads to the diagnosis of sigmoid adenocarcinoma.
CONCLUSIONS: Although rare, sciatica caused by S. gallolyticus infection of the spinal epidural space may serve as the initial presentation of colorectal cancer. Physicians should be aware of the strong association between S. gallolyticus and colorectal cancer. Based on what we currently know about the condition; a thorough systematic assessment of occult neoplasia for patients with S. gallolyticus infection is recommended.

Odontoid osteomyelitis is a rare infectious disease that manifests as fever and posterior neck pain, while crowned dens syndrome is a relatively common inflammatory disorder with similar signs and symptoms. We describe the case of a 90-year-old woman presenting with fever, posterior neck pain, throat pain, and headache. Crowned dens syndrome was initially diagnosed based on the clinical picture and calcification around the odontoid process on cervical spine CT. However, the diagnosis was revised to odontoid osteomyelitis following the detection of Staphylococcus aureus in blood cultures that were performed due to the presence of headache. Infectious complications included spinal epidural abscess extending to the hypoglossal canal and osteomyelitis spreading to the clivus. Nonetheless, the patient achieved complete recovery after 13 weeks of antimicrobial therapy. No reports of odontoid osteomyelitis with calcification around the odontoid process have been reported. This case underscores the importance of avoiding a hasty diagnosis of crowned dens syndrome when calcification around the odontoid process is observed in patients presenting with fever and posterior neck pain. It is crucial to perform a thorough medical history review and physical examination to exclude other conditions. In cases where infection is suspected, blood cultures and cervical spine MRI are essential to investigate odontoid osteomyelitis and other complications.
