A case of spontaneous spinal epidural hematoma mimicking transient ischemic attack.

Spontaneous spinal epidural hematoma (SSEH), a disease with exact etiology unknown, is characterized by acute onset of neck or back pain and rapidly progressive nerve root or spinal cord compression. It is rare in clinical practices, with a prevalence of approximately one in a million. Due to the lack of population-based epidemiological survey data for SSEH, clinicians have a serious lack of understanding of the disease and are prone to miss the best time for treatment, leaving patients with neurological dysfunction which is difficult to recover. In this paper, we report a case of SSEH with rare clinical manifestations, to improve clinicians' understanding of SSEH. The patient was mainly characterized by episodic left lower limb weakness and had been misdiagnosed as TIA.

Neurological severity evaluation using magnetic resonance imaging in acute spontaneous spinal epidural haematomas.

PURPOSE: This study aimed to elucidate the severity of neurological deficits in a large series of patients with acute spontaneous spinal epidural haematoma (SSEH) using magnetic resonance imaging (MRI). METHODS: We included 57 patients treated for acute SSEH at 11 institutions and retrospectively analysed their demographic and MRI data upon admission. We investigated MRI findings, such as the haematoma length and canal occupation ratio (COR). The neurological severity of SSEH was assessed based on the American Spinal Injury Association score on admission. RESULTS: Of the 57 patients, 35 (61%) presented with severe paralysis. The MRI analysis showed that SSEH was often located in the cervical spine, dorsal to the spinal cord, and spread over more than three vertebrae. No differences in age, sex, and aetiology were found between patients with and without severe paralysis. The hypo-intensity layer encircling the haematoma, intra-haematoma heterogeneity, and increased CORs were observed more frequently in the severe paralysis group. Furthermore, pathological examination of a dissected haematoma from one patient with a hypo-intensity layer revealed a collagen layer around the haematoma, and patients with intra-haematoma heterogeneity were more likely to have a bleeding predisposition. CONCLUSIONS: In this large series of patients with SSEH, we identified some MRI features associated with severe paralysis, such as the hypo-intensity layer, intra-haematoma heterogeneity, and increased COR. Accordingly, patients with these MRI characteristics should be considered for early surgical intervention.

Rupture of the retrocorporeal artery: a rare cause of spontaneous spinal epidural haematoma.

A 22-year-old man presented with a sudden backache and paraplegia (ASIA = B). Magnetic resonance imaging showed an anterior pan-spinal epidural haematoma. Digital subtraction angiography was performed and ruled out an underlying vascular malformation but showed an active contrast media leakage into the T-4 ventral epidural space with a pattern of pseudo-aneurysm. A rupture of a T-4 retrocorporeal artery was considered as the aetiology, possibly caused by a haemorrhagic sub-adventitial dissection. Treatment consisted in the embolisation of both the pseudo-aneurysm and the parent artery with liquid acrylic glue, followed by neurosurgical decompression in emergency. The patient had totally recovered (ASIA = E) by the 10-month clinical follow-up.

Anterior Cord Syndrome Due to Spontaneous Spinal Epidural Hematoma.

Spontaneous spinal epidural hematoma (SSEH) represents a rare clinical entity with an indeterminate etiology. Timely diagnosis and intervention are imperative due to the significant risk of permanent neurological deficits in the absence of appropriate treatment. This case report presents an instance of SSEH with no clear etiology. The patient arrived at the emergency department with paraplegia, urinary and fecal incontinence, and loss of pain and temperature sensation. She reported that these symptoms began abruptly after sneezing. The patient denied any pertinent medical history or family history. The patient initially experienced epigastric pain, which progressed to paresthesia. Magnetic resonance imaging confirmed an epidural hematoma extending from T2 to T8, necessitating immediate neurosurgical intervention. Although the patient was expected to recover within 72 hours postoperation, her symptoms persisted. Based on her clinical presentation, a diagnosis of anterior cord syndrome secondary to SSEH was confirmed.

Paralysis of the lower limbs caused by spontaneous spinal epidural hematoma: A case report.

INTRODUCTION AND IMPORTANCE: Spontaneous spinal epidural hematoma (SSEH) is a rare surgical emergency, often with acute onset, causing severe spinal cord injury. This report presents a case of SSEH treated by surgery to enhance understanding of this disease. CASE PRESENTATION: A 76-year-old male patient sought medical care for unexplained sudden chest and back pain and paralysis of both lower extremities. Magnetic resonance imaging (MRI) confirmed the occupation of thoracolumbar spinal canal. The blood clot was completely removed by emergency surgery, and then the neurological function recovered. CLINICAL DISCUSSION: Spontaneous spinal epidural hematoma is an uncommon disease, its acute onset, resulting in difficult to recover spinal cord injury, or even permanent paralysis. Therefore, early diagnosis and early operation are the key to the protection of neurological function. CONCLUSIONS: Surgical intervention is the first choice for treatment, especially in acute and subacute spontaneous spinal epidural hematoma. Once diagnosed, and there are no contraindications, it is recommended to remove and decompress the hematoma as soon as possible.

A Rare Case of a Spontaneous Thoracic Epidural Hematoma in a Young Male Weightlifter.

Spontaneous spinal epidural hematoma (SSEH) is the accumulation of blood in the epidural space of the spinal cord. Acute SSEH is a rare phenomenon that presents with a wide variety of neurologic symptoms and most often is a surgical emergency. We present a previously healthy 34-year-old male with sudden onset progressive weakness and tingling in the right lower extremity that progressed to the left lower extremity while bench pressing weights, resulting in complete lower extremity paralysis. Magnetic resonance imaging (MRI) revealed a 3.0 cm extradural mass centered in the dorsal and left lateral canal. After a T1-T4 hemilaminectomy was performed which was followed by inpatient rehabilitation, the patient had a favorable outcome improving from The American Spinal Injury Association Impairment Scale (AIS) grade A, complete impairment, to AIS grade C, incomplete impairment on discharge. Initially, the patient had complete motor and sensory paralysis below the level of T4, and upon discharge, the patient was able to attain modified independence in activities of daily living, mobility, and transfer. Due to the lack of risk factors for SSEH in this patient, the etiology is most likely related to the Valsalva maneuver while weightlifting. Lesions in the thoracic region with rapid progression of neurologic symptoms are indicators of poor prognosis, so this case highlights the importance of prompt recognition and intervention for improved outcomes to prevent devastating neurologic defects.

Successful treatment of thoracic myelopathy caused by spontaneous spinal epidural hematoma (SSEH) combined with calcification of the ligamentum flavum (CLF) by posterior percutaneous endoscopic surgery (PPES): A case report.

Study Design: A retrospective case report. Objective: To report a case who developed deteriorated paraplegia by spontaneous spinal epidural hematoma (SSEH) based on calcification of the ligamentum flavum (CLF) at the T10-11 level, achieved full neurological recovery following posterior percutaneous endoscopic surgery (PPES). Summary of Background Data: CLF rarely occurs at the thoracic spine, and the symptom usually progress slowly. SSEH is another rare spinal lesion that might progress rapidly and cause emergent severe spinal cord compression syndrome. Coexistence of SSEH and CLF at the same thoracic level was rarely reported in English literature. Methods: A 65-year-old man presented to our hospital with the complaint of sensorimotor loss on the lower limbs and dysfunction of bladder for 1 day after a progressive weakness and numbness of the lower limbs for 3 months. MR examination found a dorsal protruding mass at the T10-11 level, while computed tomography (CT) found the protruding mass contained scattered calcified deposits. The patient was diagnosed with thoracic CLF. Decompression via PPES was carried out to realize bilateral decompression through a unilateral approach. Results: During the operation, the protruding mass was found to be composed of SSEH and CLF together. After the operation, the patient's neurological function recovered quickly. One week later, the patient could walk by himself. After 3 months, complete neurological function had recovered. Conclusion: SSEH could develop based on CLF at thoracic level and cause serious neurological dysfunction. PPES might be an advisable method to remove CLF and evacuate SSEH with good clinical results.

Spontaneous thoracolumbar epidural hematoma in an apixaban anticoagulated patient.

BACKGROUND: Spontaneous spinal epidural hematomas (SSEHs) are often attributed to anticoagulation. Although they are rare, they may contribute to significant morbidity and mortality. CASE DESCRIPTION: An 83-year-old female with a history of atrial fibrillation on apixaban, presented with 4 days of back pain, progressive lower extremity weakness and urinary retention. When the patient's MRI showed a dorsal thoracolumbar SSEH, the patient underwent a T10-L3 laminectomy for hematoma evacuation. Within 2 postoperative months, her neurological deficits fully resolved. CONCLUSION: Apixaban is associated with SSEH resulting in severe neurological morbidity and even mortality. Prompt MRI imaging followed by emergency surgical decompressive surgery may result in full resolution of neurological deficits.

Spontaneous Spinal Epidural Hematoma After Normal Spontaneous Delivery with Epidural Analgesia: Case Report and Literature Review.

BACKGROUND: Pregnancy is a known risk factor for spontaneous spinal epidural hematoma. During cesarean section or vaginal delivery, the unstable hemodynamic status that may occur owing to fluctuation of intra-abdominal pressure increases the possibility of spontaneous spinal epidural hematoma. During labor and the postpartum period, neurologic symptoms may be masked by labor pain or anesthesia block, which makes early diagnosis difficult, especially in the obstetric clinic without a neurologist or neurosurgeon. CASE DESCRIPTION: A 28-year-old woman who had a normal spontaneous delivery under epidural anesthesia developed bilateral lower limb flaccid paralysis and loss of sensation 12.5 hours after delivery. Magnetic resonance imaging showed a 5.2 × 0.9 × 2 cm spinal epidural hematoma with severe spinal cord stenosis at the T2-T5 level with no evidence of a vascular anomaly. After emergent evacuation of the spinal epidural hematoma, lower limb muscle power improved from 0/5 to 1/5, and sensation gradually returned to bilateral lower limbs 22 days postoperatively. Deep vein thrombosis developed at 35 days postoperatively, and an inferior vena cava filter was implanted with urokinase infusion for thrombolytic therapy. She was discharged on day 52 after admission, and lower limb muscle power returned to normal after 3 months. CONCLUSIONS: Clinicians should observe postpartum women for signs of myelopathy or back tenderness and closely monitor neurologic function until anesthesia has run its course. A prompt diagnosis can enable prompt intervention.

Case of Acute Onset Postpartum Paraplegia: Spontaneous Spinal Epidural Hematoma-A Rare Entity.

Study Design Present study is a case report. Objective This study was to present a rare case of acute postpartum paraplegia due to spontaneous spinal epidural hematoma (SSEH). Background SSEH with incidence rate of 0.1 per 100,000 per year is an extremely rare cause of sudden onset neurological deficit in postpartum patients with no predisposing factors or intrapartum factor causing SSEH resulting in paraplegia. Material and Methods We hereby present our case of acute onset postpartum paraplegia which on magnetic resonance imaging (MRI) shows epidural hematoma around thoracic 12 to lumbar 2 (T12-L2) vertebral regions with adjacent cord changes. MRI is the investigation of choice in such cases which helps in proper timely management of patient. We planned the patient for surgical decompression of hematoma. Results Patient showed rapid reversal of neurological symptoms in postoperative period. Conclusions Acute onset postpartum paraplegia in a healthy female with no significant past history, predisposing factors or intrapartum factors may be caused by SSEH and it should be managed on emergency basis as early and proper treatment has an excellent prognosis as seen in our case.
