Spinal Epidural Hematoma:

Spontaneous spinal epidural hematoma: a case report

Background

Spinal epidural hematomas usually occur under certain conditions; they rarely occur spontaneously. The prevalence of spontaneous spinal epidural hematoma is ~ 0.1 per 100,000, and the male-to-female ratio is approximately 1.4 to 1. Herein, we describe a rare case of spontaneous spinal epidural hematoma.

Case presentation

A 63-year-old Taiwanese woman, with underlying hypertension, anemia, and a history of cardiovascular accident without sequela, was admitted to our emergency department with a chief complaint of sudden bilateral weakness in the lower limbs. Magnetic resonance imaging revealed a spontaneous epidural hematoma. The patient underwent emergency surgery to remove the epidural hematoma and laminectomy for decompression. The bilateral lower limb weakness was alleviated immediately after the surgery.

Conclusion

In patients with no risk factors related to spinal epidural hematoma, symptoms of bilateral lower limb weakness must be investigated carefully because this condition may occur spontaneously.

Spinal Emergencies in Primary Care Practice

Atraumatic spinal emergencies often present a diagnostic and management dilemma for health care practitioners. Spinal epidural abscess, cauda equina syndrome, and spinal epidural hematoma are conditions that can insidiously present to outpatient medical offices, urgent care centers, and emergency departments. Unless a high level of clinical suspicion is maintained, these clinical entities may be initially misdiagnosed and mismanaged. Permanent neurologic sequela and even death can result if delays in appropriate treatment occur. A focused, critical review of 34 peer-reviewed articles was performed to identify current data about accurate diagnosis of spinal emergencies. This review highlights the key features of these 3 pathological entities with an emphasis on appropriate diagnostic strategy to intervene efficiently and minimize morbidity.

Massage-induced spinal epidural hematoma presenting with delayed paraplegia

BACKGROUND

Spinal epidural hematoma (SEH) is an uncommon but serious emergency condition rare cases of spontaneously or following a minor traumatic event without bony injury.

OBJECTIVE

We report the rare case of SEH associated with traditional massage initially presenting with delayed lower paraplegia.

CASE REPORT

A 20-year-old man presented with bilateral lower extremity weakness and numbness 3 h prior to presentation. 3 days prior he was given a layperson Thai massage by a friend. Magnetic resonance imaging revealed a spinal epidural lesion suspicious for hematoma extending from C6 to T2 levels. Emergent surgical intervention for cord decompression was performed. An epidural hematoma with cord compression at C6-T2 levels was identified intraoperatively. No evidence of abnormal vascular flow or AV malformations was identified. Similar to chiropractic manipulation, massage may be associated with spinal trauma.

CONCLUSION

Emergency physicians must maintain a high index of suspicion for spinal epidural hematomas in patients with a history of massage or chiropractic manipulation with neurologic complaints, because delays in diagnosis may worsen clinical outcome.

Spontaneous spinal epidural hematoma secondary to extradural arteriovenous malformation in a child: a case-based update

INTRODUCTION

The aim of this study was to report a rare pediatric case of spontaneous spinal epidural hematoma (SSEH) mimicking Guillain-Barré syndrome (GBS), secondary to an epidural arteriovenous malformation (AVM). Furthermore, a case-based update and insight into the entity is attempted.

METHODS

An 8-year-old male presented with progressing severe lower limb weakness and no traumatic history. Presentation was mimicking GBS with ascending symptoms. Magnetic resonance (MR) scan revealed a dorsal epidural mass, extending from C6-C7 to T2, compressing the spinal cord. Emergency laminoplasties and surgical evacuation of the hematoma were performed. An up-to-date review of reported SSEH cases in children was conducted, with emphasis on underlying vascular malformations (epidural AVMs in particular). Pathogenesis, predisposing factors, imaging, diagnosis, treatment and outcome are discussed.

RESULTS

The hematoma was successfully evacuated. A vascular membrane on the dura was peeled off and sent for histopathology. There was no evidence of intradural vascular penetration. The patient improved postoperatively and was able to walk with support 7 months later. Histology revealed closely packed thin-walled angiomatous structures with wide lumens (filled with red blood cells) with walls composed of collagen and smooth muscle fibers, findings consistent with AVM.

CONCLUSIONS

Non-traumatic SSEH is rare in the pediatric population. Although vascular malformations are suspected, they are extremely rarely identified histopathologically. This case represents one of the very few reports of pediatric SSEH caused by a histologically proven, purely epidural AVM. High index of clinical suspicion and low threshold for MR can lead to timely diagnosis and prompt treatment with good functional outcome.

Vertebral artery dissection as an extremely rare cause of spinal epidural hematoma: case report and review of the literature

OBJECTIVE

To present a patient with a cervico-thoracic ventrally located epidural hematoma caused by dissection and subsequent bleeding of the cervical portion of the vertebral artery.

SUMMARY AND BACKGROUND DATA

Non traumatic epidural hematoma is a rare entity. The etiology usually is not clarified: a venous origin is usually suspected although an arterial source is also possible.

CLINICAL REPORT

A 32-year-old woman presented with a ventrally located cervico-thoracic epidural hematoma caused by non traumatic dissection and dissecting aneurysm rupture of the cervical portion of the vertebral artery. The dissection was demonstrated by magnetic resonance imaging and digital subtraction angiography. The patient had no neurological symptoms and was treated by conservative methods. Follow up imaging showed healing of the vertebral artery and resorption of the epidural hematoma.

CONCLUSION

Dissection of the cervical portion of the vertebral artery with subsequent perivascular bleeding is not well recognized as a possible cause of a spinal epidural hematoma. Even though this entity and the underlying cause may be rare, we suggest a vigilant search for vertebral artery injury in cases of ventrally located cervical and upper thoracic epidural hematoma.

Anticoagulation in pregnancy and neuraxial blocks

The peripartum management of the anticoagulated parturient represents a significant clinical challenge to both the obstetrician and the anesthesiologist. This review discusses the causes of thrombosis in the pregnant population, the anticoagulants used for prophylaxis, and treatment of these disorders, along with recommendations for neuraxial blockade in parturients who receive peripartum anticoagulation.

Epidural Hematoma Presenting with Severe Neck Pain without Neurological Deficit - A Late Complication of Posterior Cervical Spine Surgery: Presentation of Three Unusual Cases

Postoperative epidural hematoma (EDH) usually present with neurological deficit. Massive EDH presenting with only severe pain without neurological deficit are rare. Atypical presentations of postoperative EDHs may lead to delayed diagnosis and treatment. We present three such cases after posterior cervical spine surgery. Three patients presented with severe neck pain and spasms without motor deficits several days after posterior cervical decompressive procedures. Imaging studies identified compressive EDHs at the surgical site with severe compression of the spinal cord. All were treated with emergent decompression, with resulting improvement of symptoms and pain relief without further neurological sequelae. In conclusion, postoperative EDHs after posterior cervical spine surgery may result in minimal neurological deficit. Our report reminds surgeons to keep this possibility in mind when patients complain of unusually severe neck pain and spasms after posterior cervical spine surgery.
