Epidural hematoma (spinal)
Background
- Presentation and initial management are similar; difference is level of neuro deficit
Epidural compression syndromes
- Syndromes
- Causes
Etiology
- Epidural abscess
- Malignancy
- Massive mid-line disk herniation
- Spinal canal hemorrhage
Clinical Features
Epidural compression syndromes table[1]
Syndrome | Spinal cord compression | Conus medullaris syndrome | Cauda equina syndrome |
Location of lesion | Lesions at vertebral level L2 | ||
Spontaneous pain | Unusual and not severe; bilateral and symmetrical in perineum or thighs | Often very prominent and severe, asymmetrical, radicular | |
Motor findings | Deficits usually affect both legs but are often asymmetric | Not severe, symmetrical; rarely twitches | May be severe, asymmetrical, fibrillary twitches of paralyzed muscles are common |
Sensory findings | Weakness in lower extremities, paresthesias/sensory deficits, gait difficulty | Saddle distribution, bilateral, symmetrical, disassociated sensory loss (impaired pain and temperature with sparing of tactile) | Saddle distribution (75% pts), may be asymmetrical, no dissociation of sensory loss |
Reflex changes | Achilles reflex may be absent | Patellar and Achilles reflexes may be absent | |
Sphincter disturbance | Bladder and rectal sphincter paralysis usually reflect the involvement of S3-S5 nerve roots | Early and marked (both urinary and fecal) | Late and less severe (60-80% pts) |
Male sexual function | Impaired early | Impairment less severe | |
Onset | Sudden and bilateral | Gradual and unilateral | |
Other | Urinary retention with or without overflow incontinence (Sn 90%, Sp 95%) |
Differential Diagnosis
Lower Back Pain
- Spine related
- Acute ligamentous injury
- Acute muscle strain
- Disk herniation (Sciatica)
- Degenerative joint disease
- Spondylolithesis
- Epidural compression syndromes
- Thoracic and lumbar fractures and dislocations
- Cancer metastasis
- Spinal stenosis
- Transverse myelitis
- Vertebral osteomyelitis
- Ankylosing spondylitis
- Spondylolisthesis
- Discitis
- Spinal Infarct
- Renal disease
- Intra-abdominal
- Abdominal aortic aneurysm
- Ulcer perforation
- Retrocecal appendicitis
- Large bowel obstruction
- Pancreatitis
- Pelvic disease
- Other
Spinal Cord Syndromes
- Complete spinal cord transection syndrome
- Anterior cord syndrome
- Central cord syndrome
- Brown-Séquard syndrome
- Epidural compression syndromes
Evaluation
- Emergent MRI
- If considering compression due to neoplasm obtain scan of entire spine
- Consider Bladder scan/ultrasound for bladder volume (post-void residual)
Management
General Epidural Compression Syndrome Management
- Dexamethasone: at least 16 mg IV as soon as possible after assessment[2]
- Note: dexamethasone can be used to reduce compressive edema from epidural metastases, but is more likely to worsen an infection from spinal epidural abscess.
- Consult spine service
- Consider foley for bladder decompression
