Spontaneous spinal epidural hematoma (SSEH) is a rare condition with an incidence of 0.1 in 100,000 population. These are usually seen in the lumbar region in patients above 40 years and in the cervical and dorsal spine in younger patients. Posterior or dorsal epidural hematomas are more common than ventral hematomas. Patients present with sharp pain in the neck or back with or without neurological deficit. We present a case of a 20-year-old male who presented with quadriparesis and bowel and bladder incontinence for 5 days. No history of trauma or other aggravating factors were present. Magnetic resonance imaging revealed a posterior epidural hematoma with cord compression and edema. Patient underwent surgery and hematoma was evacuated. Patient symptoms improved gradually. Because of the severe preoperative neurological deficit and delay in surgery, patient had mild residual neurological deficit in the early post op period, which resolved over a period of two months

| Introduction|| |
Spontaneous spinal epidural hematoma (SSEH) is a rare condition first described by Blauby in 1808, with an incidence of 0.1 in 100,000 people per year.
It is usually seen in the fourth and fifth decade of life, commonly affecting the lumbar region in patients aged >40 years and the cervical and thoracic region in patients aged <40 years. Males are slightly more affected than females (M:F = 1.4:1).
Clinical presentation is usually due to sharp neck pain or back ache which may progress to paraparesis or quadriparesis depending on the location. Ventral SSEH are uncommon as the dural sac is firmly attached to the posterior longitudinal ligament. The dorsal aspect is composed of fatty tissue, hence posterior or dorsal SSEH are more common.
The present case involves a young male who presented with quadriparesis with no history of preceding trauma. In such a scenario, SSEH has to kept in the list of differential diagnosis as this condition requires prompt surgical management.
| Case Report|| |
A 20-year-old male had presented to the casualty with complaints of sudden onset of quadriparesis for 5 days. There was history of loss of sensation to touch and pain up to xiphisternum for 3 days and bowel and bladder incontinence for 2 days. There was no history of trauma or fall. No co-morbidities were present. There was no history of addictions.
Patient had similar complaints (paraparesis) five years ago which was treated conservatively. No imaging was done at that time.
The laboratory tests such as complete blood profile, liver function test, blood creatinine, electrolytes, activated partial thromboplastin time, and international normalised ratio were within normal limits. The patient was normotensive.
The neurological examination revealed loss of strength of the bilateral upper and lower extremities. Loss of skin sensation was noted below the T4 vertebral level. Babinski reflex was positive bilaterally.
On MR imaging, an elliptical collection was noted in the posterior epidural space from C4 to C7 level, showing mild high signal on T1-weighted images and heterogeneous high signal intensity on T2-weighted images. The collection was seen to compress and displace the cord anteriorly. Subtle altered signal intensity changes were noted in the cord at that level, suggestive of cord edema [Figure 1] and [Figure 2].

C4-C5 and C5-C6 laminectomy was done with evacuation of hematoma.
Patient gradually gained sensation and pain stimulus on the third postoperative day and was able to move his toes and fingers on the seventh postoperative day. MRI done 2 weeks later showed no residual epidural collection with postlaminectomy changes. Abnormal cord signal intensity was noted to persist [Figure 3]. In follow-up done 2 months after surgery, patient had complete recovery with no neurological deficit.

| Discussion|| |
Spontaneous spinal epidural hematoma is an uncommon condition that presents with acute neck pain or backache with or without neurological deficit. They can be divided into traumatic and nontraumatic (spontaneous) causes.
Traumatic spinal epidural hematoma follows any spinal surgery, vertebral fracture, lumbar puncture, or epidural catheterisation.
In spontaneous spinal epidural hematoma, 17–30% of patients have history of use of anticoagulants. Other causes include vascular malformations, neoplasms, infections, and idiopathic causes. However, in approximately 40–60% of the cases, the etiology is unknown,
Two hypotheses have been postulated:
- 1) venous origin: rupture of the venous plexus in the spinal epidural spaces as these are valveless, and any increase in intrathoracic and intraabdominal pressure is directly transmitted to the epidural veins,,
- 2) Arterial: minimal impairment or laceration in the epidural artery caused by low pressure within the venous plexus compared to the intrathecal pressure. The rapid compression of the spinal cord by the epidural hematoma also points to an arterial bleed.,
Diagnosis of SSEH is difficult to establish prior to the onset of neurological deficit. Therefore, the differential diagnosis of SSEH should include pulmonary emboli, spontaneous pneumothorax, and acute myocardial infarction in the absence of neurological deficit and should include transverse myelitis, Guillain Barre Syndrome, epidural subarachnoid bleeding, and acute spinal cord ischemia in the presence of neurological deficit.
Our patient had neurological deficit and the other differentials were excluded by MRI imaging. Contrast MRI was performed and revealed no abnormal enhancement. MR angiography was not performed. Spinal arteriovenous malformation appears as multiple tortuous flow signal voids on both T1 and T2 images and was ruled out on MRI.
In the review of recently published case reports,,,,,,, we found eight patients with SSEH, age range between 19 years and 70 years (5M, 3F). Spinal epidural hematoma was located in the cervical spine in three patients who presented with neck pain and upper limb weakness. In the rest, hematoma was located in the dorsal spine and these presented with paraparesis with one patient also having bladder incontinence.
All patients underwent surgical treatment, four undergoing hemilaminectomy, and the rest total laminectomy. Six of these patients had complete recovery with no residual neurological deficit while two patients had mild residual symptoms. Also included in this review is a case of 60-year-old female with epidural hematoma in the dorsal spine which the authors conclude was due to intake of herbal medicine.
Imaging of choice is MRI. MRI can depict the location and size of hematoma. It can also reveal extent of spinal cord compression and cord edema.
Epidural hematoma appears as lenticular shape in the epidural space with well-defined borders, and may appear hyperintense on T1 images in the acute phase. With contrast, the periphery of the hematoma and adjacent dura may enhance. Ongoing hemorrhage will show a central enhancing area on post contrast T1 images.
MRI can differentiate SSEH from its mimics such as epidural tumor or abscess, acute herniated intervertebral disc, acute spinal cord ischemia, spondylitis and transverse myelitis.
Treatment of choice is evacuation of the hematoma. Conservative management is indicated in patients who present with radicular symptoms without neurological deficit, patients who show improvement of the neurological deficit in the early phase and in those with deranged coagulopathy..,,
Surgery within 24h after the onset of symptoms shows faster and often complete recovery, while surgery done later shows slower resolution of symptoms and with persisting residual neurological deficit. Prognosis is also affected by the level and severity of the preoperative deficit.
In conclusion, a diagnosis of SSEH should be considered in all patients presenting with acute quadriparesis and must be ruled out with MR imaging as this condition requires prompt surgical treatment.
