Acute spontaneous spinal epidural hematoma: The influence of magnetic resonance imaging on diagnosis and treatment

The incidence of spinal epidural hematoma (SEH) is estimated to be 1 per 1,000,000 patients per year; SEH can be classified as idiopathic, spontaneous, and secondary. The cause of spontaneous SEH is uncertain but it may be associated with minor trauma. SEH can compress surrounding structures, shown by clinical symptoms and signs that affect the spinal cord or nerve roots. Surgical treatment may be considered if medical treatment fails.

A 26-year-old man presented with lower back pain and significant radicular symptoms on the left side for a week. He denied previous lumbar trauma or the use of anticoagulation drugs. We used the full-endoscopic transforaminal approach (extraforaminal technique) to remove the SEH under local anesthesia. The patient was discharged home 2 days after surgery and the radicular pain disappeared completely. Three months later, follow-up magnetic resonance imaging showed that the dark-brown lesion had been totally removed.

Spontaneous SEHs are uncommon. Although lumbar laminectomy is the mainstream treatment in those with neurologic deficits caused by epidural hematomas, the percutaneous full-endoscopic transforaminal approach may be an option for certain SEHs.

Traumatic spinal epidural hematoma (TSEH) is a rare neurosurgical condition that according to conventional treatment requires prompt surgical decompression. Recent reports, however, suggest that conservative management within the acute phase after trauma also can lead to similar long-term functional outcomes without the need for immediate neurosurgical intervention.

In the present paper, we describe 2 cases of TSEH located in the ventral upper cervical spine, which presented with delayed neurologic deficits. In both cases, conservative management with steroid treatment was initiated before neurosurgical decompression, resulting in improved neurologic outcomes.

Urgent surgical decompression may not be necessary acutely in patients with TSEH who respond well to conservative therapy. Although there is currently no consensus for the initial management strategies, steroid treatment could individually tailored and applied according to the clinical condition and evolving symptoms.

Background: Spontaneous epidural hematoma is a rare condition, which usually requires urgent surgical treatment. Objectives: To report two cases of spontaneous epidural hematoma, one of which was treated conservatively, and the other surgically, and discuss the possibility of unusual spontaneous recovery and treatment decision-making. Case Report: We encountered 2 patients with spontaneous spinal epidural hematoma, both of whom were taking an anti-platelet agent, producing severe paraplegia. One patient with a hematoma at C2–T3 experienced a rapid neurological recovery while a magnetic resonance imaging scan was being performed. A complete resolution of the hematoma and complete neurological recovery ensued without surgical intervention. A second patient with a hematoma at T10–12 showed no neurological recovery up to the time emergency surgery started and was treated surgically by T10–12 laminectomy and excision of the hematoma. Neurological function returned to normal in both patients. Conclusion: The occurrence of spontaneous recovery in some patients makes the decision for surgery difficult. Emergency physicians need to be aware of the possibility of spontaneous rapid neurological recovery in patients with spinal epidural hematoma. To avoid unnecessary surgery in patients who will spontaneously have neurological recovery, neurological evaluations need to be repeatedly performed up to the time the emergency surgery begins. However, unfortunately, there is no diagnostic tool at present to identify the patients who recover spontaneously, and the interval between onset and surgery is correlated with clinical results, therefore, conservative treatment should be prescribed only for those patients who exhibit improving neurological signs early in the clinical course.

Background: Spontaneous spinal epidural hematoma (SSEH) is a rare cause of spinal cord compression that requires emergency investigation and treatment. Prompt diagnosis is essential to prevent morbidity and mortality. Objectives: Our goal was to report a case of SSEH, and to review the literature on the topic, looking particularly at the factors influencing post-operative outcome, and the symptoms and signs that would lead one to consider this rare diagnosis. Case Report: A 36-year-old man presented to the Emergency Department with paraplegia and a sensory level at T4. There was no history of trauma and he was not taking any medications. Magnetic resonance imaging revealed a large non-enhancing posterior epidural mass lesion between C7 and upper T4, causing severe cord compression at T1–T3. Post contrast scans revealed no rim enhancement. Blood investigations were unremarkable, with an international normalized ratio of 1.1. He underwent urgent decompression laminectomy within 12 h of symptom onset. Intraoperatively, thick clotted blood and prominent epidural vessels were seen. Histology revealed engorged vessels with hemorrhage and clot in the extravascular tissues. Post-operatively, the impaired neurological status remained unchanged. Conclusion: SSEH is a rare cause of spinal cord compression that requires prompt diagnosis and surgical intervention to prevent morbidity. Neurological outcome after surgical decompression depends on the severity of preoperative neurological deficits as well as the time between symptom onset and surgery.

Spontaneous spinal epidural hematoma (SSEH) is a rare emergent condition. It may result in paraplegia, quadriplegia and even death. Prompt diagnosis and emergent decompressive surgical management have been recommended to prevent mortality and morbidity. Although several factors have been associated with prognosis, controversy remains, partly due to its rarity. Thus, the history, clinical presentation, physical examination findings, radiological images, and surgical and pathological records of 30 patients with SSEH (21 male, nine female [sex ratio of 2.3:1], average age of 35 years) treated between January 2002 and September 2010 have been reviewed. The association of age, sex, hypertension, vascular malformation, vertebral level, position and extension of the hematoma, progression interval, operative interval, spinal cord edema, and preoperative neurological condition with the prognosis is discussed. The outcome was better for patients with incomplete neurological deficit (p = 0.001), lesions extending <4 vertebral segments (p = 0.026), and lesions in the thoracolumbar and lumbar region. A shorter progression interval often led to a less favorable prognosis (p = 0.017). Patients with spinal cord edema experienced a worse preoperative neurological deficit (p = 0.005) and a worse outcome (p = 0.000). Patients with a progression interval ⩽12 hours presented with a worse preoperative neurological deficit (p = 0.026). Early surgical intervention to evacuate the hematoma remains the main treatment for most symptomatic patients. Conservative treatment may be used only for those in a good preoperative neurological condition. Prognosis is associated with the preoperative neurological condition, progression internal, spinal cord edema, and extension and vertebral level of the SSEH. Patients with SSEH in the cervical or cervicothoracic region with a complete preoperative motor deficit have a higher mortality rate.
