Spinal Hematoma



In 1850, Tellegen appears to have been the first to describe the clinical symptoms of spinal cord hematoma or hematomyelia. The symptoms have not changed significantly with the passage of time and the few that have occurred, change only slightly with varying etiologies.

Spinal cord hematoma or hematomyelia is an infrequently encountered condition that is the result of several unusual disease processes. The causes of spontaneous, nontraumatic spinal cord hematoma include vascular malformations of the spinal cord (the most common), clotting disorders, inflammatory myelitis, spinal cord tumors, abscess, syringomyelia, and unknown etiologies. Traumatic events, such as spinal cord injury (closed or penetrating), and operative procedures involving the spinal cord also can cause a spinal cord hematoma. In addition, several instances of intramedullary spinal cord hematomas have been reported following lumbar or C1-C2 punctures.[1, 2]

Because of the rarity of hematomyelia, its numerous etiologies, and its varied clinical presentations, this article provides a general overview of spinal cord hematomas and briefly discusses each etiology separately. Because hematomyelia is a rare entity, treatment and outcomes, regardless of the cause, are based primarily upon anecdotal evidence and the treating surgeon's philosophy.

Since the original publication of this article, several other case reports have been published that discuss intramedullary spinal cord hematomas. These case reports, while detailing several unusual presentations of patients with intramedullary spinal cord hematomas, add little to the core concepts described in the original article. Patients suffering from intramedullary spinal cord hematomas present with severe spinal pain and significant neurological findings related to the level of spinal cord involvement; MRI with and without gadolinium is still the procedure of choice for early diagnosis; and successful outcomes depend on early diagnosis, aggressive, emergent surgical treatment and drainage of the hematoma. Even when these guidelines are followed, outcome following surgery is highly correlated with the initial neurological status of the patient.



The epidemiology of hematomyelia is based directly upon the underlying pathological process. No general statements can be made with regard to age, incidence, gender, or specificity of symptoms because these depend upon the underlying pathology.



Regardless of the cause, the almost universal initial symptom of spinal cord hematoma is sudden onset of excruciating back or neck pain. The location of this pain relates directly to the location of the underlying pathology and hematoma.

The neurological deficit caused by the hematoma also directly correlates with the region of hemorrhage. Neurological deficits vary somewhat with the underlying etiology. The deficit associated with a vascular malformation occurs suddenly, along with the pain, and does not usually increase substantially over time. The deficits associated with hematomas from other etiologies may lag the initial onset of pain by several hours. The deficit also may evolve over a period of 2-24 hours, or it may even take days.

Imaging Studies

MRI, with and without gadolinium, is the diagnostic procedure of choice for investigating the possibility of a spinal cord hematoma. Spinal MRI demonstrates both the hematoma and the additional underlying pathology. Moreover, MRI imaging demonstrates other pathology if a spinal cord hematoma is not the cause of the patient's symptoms.[12]

Surgical Therapy

Outcome and Prognosis

Too few data are available to derive solid outcome and prognosis figures for this disease. As noted above, however, the ultimate outcome of a patient correlates strongly with their initial neurological status; in other words, a patient with minimal findings upon presentation will likely experience a much better outcome than a patient who presents with a significant neurological deficit.

Future and Controversies

Spinal cord hematoma or hematomyelia is a fairly rare entity that is usually caused by some underlying pathology or disease process. These causative diseases include AVMs, coagulopathies, tumors, syringomyelia, and vasculitis. No associated problems occur in a subset of these patients.

Clinical presentation is usually a sudden onset of spinal pain accompanied by neurological deficits correlative with the site of the clot. Treatment is aimed at correcting the underlying pathology or clotting disorder and at removing the clot. Timing of treatment and its results are still controversial.
