Spontaneous cervical epidural hematoma masquerading as an abscess on magnetic resonance imaging scan

Prognostic factors and surgical outcomes of spontaneous spinal epidural haematoma: a systematic review and meta-analysis

Spontaneous spinal epidural haematoma (SSEH) is a rare disease defined as blood accumulation within the vertebral epidural space without a cause identified, which can lead to severe neurological deficits. We aim to provide a comprehensive understanding of the prognostic factors affecting surgical outcomes in true SSEH and propose a critical time frame for operative management. A systematic literature search was performed and registered, using OVID Medline and EMBASE, in line with the PRISMA guidelines. Relevant demographic, clinical, surgical, and outcome data were extracted. The ASIA scale was uniformly used throughout our systematic review. Statistical analysis was performed via logistic regression. Of the 1179 articles examined, we included 181 studies involving 295 adult patients surgically treated for SSEH. SSEH were most commonly found in the cervicothoracic spine, with 2-4 spinal segments most commonly involved. Multivariable logistic regression model showed that the following factors were statistically significant in the post-operative outcome: operation type (P = 0.024), pre-operative neurologic status (P < 0.001), use of warfarin (P = 0.039), and operative interval (P = 0.006). Our retrospective analysis confirms the reversibility of severe neurological deficits after surgical intervention, with a prognosis of post-operative outcomes determined by the use of warfarin, pre-operative ASIA grade, and above all surgical evacuation within 12 h.

Delayed Presentation of a Cervical Spinal Epidural Abscess of Dental Origin after a Fall in an Elderly Patient

Spinal epidural abscesses are an uncommon cause of spinal cord injury but, depending on the size and presence of neurological deficits, urgent neurosurgical intervention may be required. We present a unique case of a patient presenting with a spinal epidural collection several days after a fall. While a spinal epidural hematoma was suspected based on the patient’s history and MRI findings, a spinal epidural abscess was found during surgery. The patient underwent laminectomy and instrumented fusion with successful treatment of her infection.

Infected epidural hematoma of the lumbar spine associated with invasive pneumococcal disease

Spinal epidural abscess (SEA) and spinal epidural hematoma (SEH) are neurologic emergencies with distinct etiologies and treatment. Despite similarities on magnetic resonance imaging (MRI), their differentiation is usually possible with meticulous history taking and neurologic examinations. We report an unusual case of SEA that developed from preceding SEH, posing a diagnostic challenge to physicians. A 65-year-old diabetic man suddenly experienced back pain and weakness of both legs when he lifted heavy luggage. He was afebrile, and his laboratory tests were mostly unremarkable. Spinal MRI consisting of T1-weighted, T2-weighted, and fat-suppressed T2-weighted images revealed an epidural mass over the L2-L4 spinous process. He was diagnosed with SEH based on his symptoms and MRI findings, and was treated conservatively using steroid pulse therapy. Despite initial improvement, he suddenly developed into septic shock and coma on the 10^th hospital day, and died shortly thereafter. An autopsy revealed massive pus accumulation in the lumbar epidural space and brain, and a postmortem diagnosis of infected SEH associated with invasive pneumococcal disease was established. Serial MRI studies, including diffusion-weighted and/or gadolinium-enhanced T1-weighted images are warranted in patients with a presumed diagnosis of SEH receiving steroid therapy to detect such infectious transformation.

Spontaneous cervical epidural hematomas with acute hemiparesis should be considered a contraindication for intravenous thrombolysis: a case report with a literature review of 50 cases

We herein report the case of a 63-year-old woman with an acute spontaneous cervical epidural hematoma who presented with acute hemiparesis and was successfully managed with surgery. Based on a literature review of 50 cases of spontaneous cervical epidural hematomas, we concluded that the relatively high frequency of hemiparesis (12 of 50 cases, 24%) is the result of the fact that epidural hematomas are predominantly distributed dorsolaterally in the region of the mid and lower cervical spine, leading to unilateral cervical cord compression. Clinicians should keep in mind that acute hemiparesis can be caused by spontaneous cervical epidural hematomas for which intravenous thrombolysis is contraindicated.

Spontaneous Spinal Epidural Hematoma: A Retrospective Study on Prognostic Factors and Review of the Literature

Objectives

The spontaneous spinal epidural hematoma (SSEH) is a rare clinical entity. Patients typically present with sudden onset back pain followed by neurological deficits.

Methods

Diagnosis of SSEH is usually made with MRI and standard treatment is surgical evacuation. In 1996, Groen published the most comprehensive review on the SSEH in which he analyzed 333 cases. We review 104 cases of SSEH presented in the English literature since the last major review and add three of our own cases, for a total of 107 cases.

Results

Our patients presented with back pain and neurologic deficits. Two made excellent functional recovery with prompt surgical decompression while one continued to have significant deficits despite evacuation. Better postoperative outcome was associated with less initial neurological dysfunction, shorter time to operation from symptom onset and male patients.

Conclusion

We discuss the etiology of SSEH and report current trends in diagnosis, treatment, and outcome.

Diagnosis and microsurgery of symptomatic spontaneous spinal epidural hematoma

BACKGROUND

Symptomatic spontaneous spinal epidural hematoma (SSEH) is an uncommon cause of cord compression that needs emergent treatment. Without effective management of the symptomatic SSEH, irreversible severe spinal injury would be possible.

OBJECTIVES

We aimed to investigate the diagnosis and surgical management of symptomatic SSEH.

METHODS

Five cases of symptomatic SSEH with favorable neurological recovery after emergent microsurgery were prospectively analysed.

RESULTS

The main clinical presentations were root pain and palsy. The main manifestations of MRI were long-segment epidural lesions of high intensity on T1- and T2-weighted images without enhancement. Laminectomy via posterior approach and hematoma removal were undergone for all patients. All patients achieved full neurological recovery without complications.

CONCLUSIONS

MRI manifestation assisted with the main clinical symptoms may aid the preoperative diagnosis of SSEH, and the delay in obtaining preoperative Digital subtraction angiography is worthwhile, especially for those with progressive neurological deterioration.
