Background:Iatrogenic or spontaneous spinal hematomas are rarely seen and present with multiple symptoms that can be difficult to localize. Most spontaneous spinal hematomas are multifactorial, and the pathophysiology is varied. Here, we present a case of a scattered, multicomponent, combined subdural and epidural spinal hematoma that was managed conservatively.
Case Description:A 38-year-old woman came to the emergency department (ED) complaining of severe neck and back pain. She had undergone a caesarean section under epidural anesthesia 4 days prior to her arrival in the ED. She was placed on heparin and then warfarin to treat a pulmonary embolism that was diagnosed immediately postpartum. Her neurological examination at presentation demonstrated solely the existence of clonus in the lower extremities and localized cervical and low thoracic pain. In the ED, the patient's international normalized ratio was only mildly elevated. Spinal magnetic resonance imaging revealed a large thoracolumbar subdural hematoma with some epidural components in the upper thoracic spine levels. Spinal cord edema was also noted at the T6-T7 vertebral level. The patient was admitted to the neurosurgical intensive care unit for close surveillance and reversal of her coagulopathy. She was treated conservatively with pain medication, fresh frozen plasma, and vitamin K. She was discharged off of warfarin without any neurological deficit.
Conclusions:Conservative management of spinal hematomas secondary to induced coagulopathies can be effective. This case suggests that, in the face of neuroimaging findings of significant edema and epidural blood, the clinical examination should dictate the management, especially in such complicated patients.

Post-traumatic, iatrogenic or spontaneous spinal hematomas (epidural and/or subdural) are rare and have different pathophysiological causes. Several factors contribute to the genesis of a spinal hematoma, such as vascular malformations, coagulopathies, thrombolytic drug administration, tumors, autoimmune diseases, pregnancy, excessive exercise, previous epidural anesthesia, cardiac surgery, and lumbar puncture.[
Here, we present a rare case of a large multicomponent, combined epidural and subdural spinal hematoma extending from the cervical spine to the low thoracic spine that was treated conservatively.
A 38-year-old woman who had recently undergone epidural spinal anesthesia for a caesarean section 4 days prior presented to the emergency department (ED) of our institute complaining of severe neck and low back pain. Postpartum, her postoperative course was complicated by dyspnea and chest pain that was found to be secondary to a new pulmonary embolism. During her initial hospitalization, she received antithrombotic therapy sustained by unfractionated heparin (with close monitoring of her clotting mechanism) and was bridged to warfarin therapy prior to her discharge to home. At the ED, she did not have any weakness, paresthesias, or changes in motor “function,” although she described some nonspecific back pain.
On examination in the ED, the patient had 5/5 strength in all muscle groups in the upper and lower extremities, no signs of sensory deficits, or signs of cauda equina syndrome, but she did have several beats of clonus in the lower extremities. Laboratory testing demonstrated only a mildly elevated international normalized ratio of 1.8, which was below the expected value. Magnetic resonance imaging (MRI) of the entire spine demonstrated a large amount of mixed epidural and subdural blood collection within the high thoracic and lumbar spine as well as cord edema near T6-7 [Figures
Thoracic magnetic resonance imaging (MRI), sagittal T2 sequence with contrast enhancement, showing extra-axial subdural abnormality involving the entirety of the thoracic spinal canal extending from the cervical to the lumbar spine (small arrows). Minor signal within the spinal cord parenchyma is most likely associated with edema (large arrow). These findings were consistent with extensive acute/subacute subdural–epidural hemorrhage

At the C6-C7 level, a pathological signal is noted within the spinal cord parenchyma with minor mass effect (right arrow)
After the diagnosis was made, the patient was admitted to the neurosurgical intensive care unit (neuroICU) for reversal of her mild coagulopathy (due to previous warfarin therapy) with the administration of fresh frozen plasma and vitamin K, as well as for pain control and surveillance. While in the neuroICU, she experienced an episode of tachycardia and shortness of breath for which she underwent thoracic computed tomographic angiography, which showed a small right basilar atelectasis. These symptoms were thought to be due to a transfusion reaction to the plasma and vitamin K. She was treated conservatively with pain control management and bedrest. After gradual mobilization, she was discharged without any neurological deficits or complications. Her atelectasis and pain were resolved; the hematoma had stabilized according to the last imaging study performed during her hospitalization. The last MRI study, obtained 9 months after her discharge, showed that the hematoma is slowly resolving. The patient is neurologically stable and is completely mobile, although she is still having episodes of low back pain and wears a brace for comfort.
Although many cases of spinal subdural or epidural hematomas have been described in the literature, this case is unique because it is a case of a mixed hematoma that was successfully managed conservatively. Although epidural anesthesia is a commonly used means of anesthesia, it can be associated with serious complications in 0.1–1 per 10000 epidural injections.[
The treatment of spinal subdural, epidural, or combination hematomas may be conservative or surgical, although the borders between these two options are sometimes subjective.[
Given our patient's recovery, we believe that clinical examination findings should dictate the management for such patients. Imaging findings, such as size of the hematoma, should never be used as the only guide for treatment strategizing.[
