What are the signs and symptoms of haematomyelia, and how urgent is its management?

Haematomyelia: Signs, Symptoms, and Urgency

Haematomyelia is a neurosurgical emergency requiring immediate recognition and urgent intervention, as it presents with acute myelopathy that can rapidly progress to permanent neurological deficit without prompt treatment.

Clinical Presentation

Cardinal Signs and Symptoms

Haematomyelia typically presents with a distinctive clinical triad:

• Sudden, severe back or neck pain at the level of hemorrhage, often described as sharp or stabbing
• Acute myelopathy syndrome developing within minutes to hours, manifesting as:
  • Motor weakness or paralysis below the lesion level (paraparesis, paraplegia, or quadriparesis depending on location)
  • Sensory deficits following specific patterns (transverse, central, anterior, posterior, or hemi-cord syndromes)
  • Autonomic dysfunction including urinary and fecal incontinence
• Radicular pain radiating along nerve root distributions 1

Specific Myelopathy Patterns

The neurological presentation depends on the hemorrhage location and extent:

• Brown-Séquard syndrome (ipsilateral motor weakness with contralateral sensory loss) is commonly reported 2
• Complete transverse myelopathy with loss of all motor, sensory, and autonomic function below the lesion
• Central cord syndrome with upper extremity weakness greater than lower extremity involvement (cervical lesions)
• Spinal shock may occur with acute severe lesions, showing reduced or absent reflexes initially 3

Temporal Progression

Haematomyelia can present in different temporal patterns 1:

• Acute (most common): sudden onset over minutes to hours
• Subacute: progression over days
• Stepwise: stuttering deterioration with multiple episodes
• Chronic: gradual worsening over weeks

Urgency of Management

This is a TRUE NEUROSURGICAL EMERGENCY

Immediate action is required within hours, not days. The urgency parallels that of acute spinal cord compression, where delays directly correlate with permanent neurological disability 4.

Time-Critical Algorithm

1. Immediate recognition (within minutes of presentation):

   • Any patient with acute back/neck pain plus new myelopathy symptoms
   • High suspicion in patients on anticoagulation 5, 1

2. Urgent neurological evaluation (within 1 hour):

   • Complete neurological examination documenting motor, sensory, and reflex deficits
   • Assess for deep pain perception (critical prognostic indicator)
   • Document sphincter function 6

3. Emergency MRI (within 2-4 hours):

   • MRI with and without gadolinium is the diagnostic gold standard 1, 2
   • T2-weighted sequences show intramedullary hyperintensity
   • T2* or susceptibility-weighted imaging demonstrates blood products 3
   • Myelography and CT are NOT helpful and waste critical time 2

4. Immediate neurosurgical consultation (concurrent with imaging):

   • Do not delay consultation waiting for imaging results
   • Surgical evacuation may be required emergently 2

Critical Pitfalls to Avoid

Do not mistake this for a less urgent condition. The following errors delay treatment:

• Attributing symptoms to musculoskeletal pain without neurological examination
• Waiting for "routine" MRI scheduling—this requires STAT imaging
• Performing CT or myelography first—these waste time and miss the diagnosis 2
• Delaying neurosurgical consultation until imaging is complete
• Failing to check coagulation status immediately in anticoagulated patients 5

Underlying Causes Requiring Specific Management

Most Common Etiologies (in order of frequency) 1:

1. Spinal vascular malformations (most common atraumatic cause):

   • Intramedullary cavernomas
   • Arteriovenous malformations (AVMs)
   • Requires definitive surgical treatment after acute phase

2. Anticoagulation therapy 5, 7:

   • Warfarin (even in therapeutic range)
   • Heparin
   • Immediate reversal required: Stop anticoagulation, give vitamin K, consider prothrombin complex concentrate

3. Bleeding disorders (hereditary or acquired)

4. Spinal cord tumors (primary or metastatic)

5. Trauma (including iatrogenic from procedures) 3

Immediate Coagulation Management

For anticoagulated patients 8:

• Check INR/PTT immediately
• Warfarin: Give prothrombin complex concentrate (PCC) PLUS vitamin K (PCC preferred over fresh frozen plasma due to faster onset)
• Stop all antiplatelet agents (aspirin, clopidogrel)
• Target platelet count >50,000/mm³ minimum, higher for neurosurgical intervention 6

Prognosis and Treatment Urgency

Surgical evacuation within hours of symptom onset offers the best chance for neurological recovery 2. Both reported surgical cases showed progressive improvement after prompt hematoma evacuation, with one patient achieving normal ambulation and another regaining continence and ambulation 9, 2.

Conversely, delayed treatment results in permanent deficits. In one case where treatment was delayed, extensive hemorrhage from C1 to conus medullaris resulted in persistent severe disability despite management, ultimately requiring euthanasia 7.

The window for meaningful recovery is measured in hours, not days. Permanent spinal cord injury from compression and ischemia develops rapidly, making this condition as time-sensitive as acute stroke or spinal cord compression from epidural abscess 4.
