PIVD at D5 + Vertebral Hemangioma at D5: Further Management

1. Determine if the hemangioma is incidental or aggressive/symptomatic
2. Plan management for the disc prolapse without ignoring hemangioma risks (especially intraoperative hemorrhage)
3. Address both lesions in an integrated manner

Step 1: Characterize the Hemangioma (Critical First Step)

MRI Assessment (Gold Standard)

• Typical/latent hemangioma: High signal on BOTH T1 and T2 (fat + vascular) - usually incidental, no treatment needed
• Aggressive hemangioma: Hypointense on T1, hyperintense on T2 - indicates a large vascular component; treat independently

Six Radiographic Criteria for Compressive Risk (Campbell's 2026)

1. Thoracic location T3-T9 (D5 falls within this range - YES, this criterion is met)
2. Entire vertebral body involvement
3. Neural arch/pedicle involvement
4. Irregular "honeycomb" appearance
5. Expanded, poorly defined cortex
6. Soft tissue swelling

Step 2: Clinical Classification

Step 3: Management Algorithm

A. If Hemangioma is Incidental (typical MRI features, no symptoms from it)

• Conservative (6-8 weeks first): NSAIDs, physiotherapy, analgesics, activity modification
• If conservative fails or neurologic compromise exists: Surgical discectomy
  • Thoracic discectomy is rare (<2% of all discectomies) - approach depends on disc type:
    • Soft disc prolapse: Thoracoscopic approach preferred
    • Hard/calcified disc: Thoracotomy or costotransversectomy
  • Surgical caution: The co-existing hemangioma at D5 increases intraoperative bleeding risk - even if "incidental," the surgeon must be prepared for vascular ooze from the vertebral body
• The hemangioma can be observed with serial MRI every 6-12 months

B. If Hemangioma is Symptomatic / Aggressive

• Effective in 50-80% of symptomatic hemangiomas
• Dose: 30-40 Gy in fractionated doses
• Useful when surgery is not feasible or lesion is moderately symptomatic
• As per the 2023 review (PMID: 37122908), radiation remains the preferred non-surgical option

• Bone cement (PMMA) injection stabilizes the vertebral body and obliterates vascular spaces
• Effective for aggressive hemangiomas with pain and vertebral instability
• Contraindicated if posterior vertebral wall is breached (cement may leak into spinal canal)
• Can be done percutaneously; inflatable bone tamps (kyphoplasty) show similar good results

• Direct intralesional alcohol injection obliterates vascular spaces
• CT angiography required beforehand to map functional vascular spaces
• Less than 1 mL of ethanol used per session to avoid neurological damage

• Indicated when surgery is planned AND hemangioma has significant vascular component
• Reduces intraoperative blood loss substantially
• Best done 24-48 hours before surgery
• Embolization alone may give temporary pain relief but neurologic improvement is variable

• Indications: progressive neurologic deficit, spinal instability, failed conservative/radiation
• Anterior resection of hemangioma + disc + reconstruction
• If large posterior element involvement: posterior decompression + instrumented fusion
• T9-L1 or appropriate segment fusion after decompression (as shown in the Campbell's surgical case at T11)

Step 4: Integrated Surgical Planning (If Both Need Surgery)

1. Pre-op CT angiography - map hemangioma vascularity and disc-cord relationship
2. Pre-op embolization - 24-48 hrs before surgery to reduce bleeding
3. Single-stage surgery preferred:
   • Anterior approach: corpectomy/discectomy + vertebral body reconstruction + cage/strut graft
   • Posterior stabilization: pedicle screw fixation for stability
4. Blood bank preparation - crossmatch at minimum 4 units
5. Neuromonitoring: Intraoperative SSEP/MEP is mandatory for thoracic cord surgery

Band-like Chest Sensation + Radiculopathy at D5 Level - Management

Why This Symptom Occurs

• A tight, band-like or constricting feeling encircling the chest
• Burning, aching, or electric pain radiating along the T5 dermatomal strip
• Numbness or paresthesia (tingling, pins and needles) along the same band
• This is intercostal neuralgia from thoracic nerve root origin

Immediate Differential Diagnoses to Rule Out

Management for D5 PIVD with Radiculopathy (Band-like Pain)

Phase 1: Conservative Management (First 6-8 Weeks) - Try This First

Medications

Physical Measures

• Relative rest (not absolute bed rest) for 1-2 weeks during acute phase
• Thoracic spine bracing/corset: Reduces motion at D4-5 level, offloads disc pressure
• Hot fomentation over paravertebral muscles for spasm relief
• Physiotherapy (after acute phase subsides):
  • Postural correction (thoracic kyphosis worsens disc pressure)
  • Core strengthening - deep paraspinal and abdominal muscles
  • Extension exercises (McKenzie-based for thoracic disc)
  • Traction - limited role in thoracic spine but may help

Interventional (Pain Clinic)

• Thoracic epidural steroid injection (TESI): Delivers corticosteroid (e.g., methylprednisolone 80mg + local anaesthetic) directly to the epidural space at D4-5 - very effective for nerve root pain
• Selective nerve root block (SNRB) at T5: Fluoroscopy/CT guided injection at the T5 foramen - both diagnostic (confirms T5 as the symptomatic level) AND therapeutic
• Intercostal nerve block: Along the T5 intercostal groove - gives temporary but good relief of the band-like pain

Important note on hemangioma: Epidural injections must be done with imaging guidance and the injectionist must be aware of the D5 hemangioma - avoid inadvertent needle trauma to the vascular lesion

Phase 2: Re-evaluate at 6-8 Weeks

Phase 3: Surgical Indications (When to Operate)

1. Progressive myelopathy - worsening weakness in legs, gait ataxia, Babinski positive
2. Bowel or bladder dysfunction - suggests cord compression, URGENT surgery
3. Persistent unremitting radicular pain not responding to 6-8 weeks of conservative treatment
4. Neurological deterioration on examination
5. Hemangioma becomes aggressive (soft tissue component, cord compression on MRI)

Surgical Options for D5 PIVD (if needed)

• Pre-operative CT angiography and embolization of hemangioma 24-48 hours before surgery
• Anterior approach gives simultaneous access to disc AND vertebral body hemangioma
• Bone cement (vertebroplasty) can be done at same setting if vertebral body is unstable
• Instrumented fusion (pedicle screws T3-T7) likely needed if corpectomy performed

D5 Vertebral Hemangioma - Management

Step 1: Classify Before Treating

Key point for this patient: The current band-like pain is most likely from the PIVD, NOT the hemangioma. However, if the hemangioma at D5 has any aggressive MRI features (T1 hypointense), it must be treated independently - because D5 is right in the high-risk zone (T3-T9).

The 6 Imaging Features of an Aggressive / Compressive Hemangioma

1. Thoracic location T3-T9 (D5 automatically fulfils this)
2. Entire vertebral body involvement
3. Neural arch / pedicle involvement
4. Irregular honeycomb trabecular pattern
5. Expanded, poorly defined cortex
6. Paraspinal soft tissue component

Treatment Options - By Indication

Option 1: Observation (Incidental / Asymptomatic)

• No biopsy, no treatment required
• Serial MRI every 12 months to monitor for change in size, signal, or soft tissue extension
• Reassure patient - vast majority of vertebral hemangiomas are completely benign and never require intervention
• Educate on red flag symptoms (new neurological symptoms, sudden worsening pain)

Option 2: Radiation Therapy (Symptomatic, No Neurological Deficit)

• Success rate: 50-80% for pain relief and arrest of progression
• Conventional external beam radiotherapy: 30-40 Gy in fractionated doses (typically 10 fractions of 3 Gy)
• Best suited when: hemangioma is painful, no cord compression, surgical risk is high
• Stereotactic radiosurgery (SRS/SBRT): Emerging option - a 2022 systematic review (PMID: 35378316) showed good local control with SRS for benign vertebral hemangiomas
• Avoid in aggressive lesions with significant vascular component - risk of radiation-induced oedema worsening cord compression
• Note: Radiation avoided in benign lesions when possible due to risk of secondary sarcomatous change (Campbell's)

Option 3: Vertebroplasty / Kyphoplasty (Aggressive, Pain + Instability, Intact Posterior Wall)

• Mechanism: PMMA (polymethylmethacrylate) bone cement injected percutaneously into the vertebral body under fluoroscopic/CT guidance - obliterates vascular spaces and stabilizes the bone
• Excellent results for pain relief and vertebral stabilization
• Strict contraindication: Posterior vertebral body cortex must be intact - if breached, cement leaks into the spinal canal causing catastrophic neurological injury
• Kyphoplasty (inflatable bone tamp first, then cement): Similar results, slightly lower cement leak risk, restores some vertebral height
• Can be combined with embolization for highly vascular lesions
• Best used when: Pain is hemangioma-related, vertebral body shows trabecular destruction, no posterior wall breach

Option 4: Percutaneous Ethanol (Sclerotherapy) Injection (Symptomatic, Highly Vascular)

• Direct intralesional injection of absolute ethanol obliterates the vascular channels
• Requires CT angiography first to map the functional vascular spaces and direct needle placement
• Dose: less than 15 mL total - higher volumes (42-50 mL reported) caused pathological fractures
• Effective for obliterating symptomatic hemangiomas
• Less commonly used now - superseded by vertebroplasty at most centres

Option 5: Transarterial Embolization (Pre-operative or Temporary Relief)

• Selective embolization of feeding vessels via femoral arterial approach
• Primary uses:
  1. Pre-operative (24-48 hrs before surgery) to reduce intraoperative bleeding
  2. Temporary relief of neurologic symptoms in patients awaiting surgery
  3. Adjunct to vertebroplasty in highly vascular lesions
• Gives temporary pain relief but not a standalone curative treatment
• Critical warning at D5 level: Must identify and protect the artery of Adamkiewicz (artery of the lumbar enlargement, usually T9-L2, but can arise as high as T5-T8). Inadvertent embolization causes anterior spinal artery syndrome (paraplegia)
• CT angiography / DSA essential before embolization to map vascular anatomy

Option 6: Surgery (Aggressive Hemangioma + Neurological Deficit / Fracture)

• Progressive myelopathy or radiculopathy from hemangioma compression (separate from the disc)
• Pathological fracture causing instability
• Failed radiation or percutaneous treatment
• Epidural extension with cord compression

• Anterior: Corpectomy (partial or complete vertebral body resection) + cage reconstruction + anterior plating
• Posterior: Decompression laminectomy + pedicle screw instrumented fusion (if posterior elements involved)
• Combined anterior-posterior: For circumferential cord compression or highly unstable lesion
• Preoperative embolization is mandatory before any surgery on a vertebral hemangioma

Management Algorithm for This Patient's D5 Hemangioma

D5 Hemangioma found on MRI (alongside PIVD)
            ↓
Check MRI carefully:
T1 bright + T2 bright? → Typical/fat-dominant
T1 DARK + T2 bright?  → Aggressive/vascular
            ↓
Count aggressive imaging features (0-6)
            ↓
0-2 features, T1 bright → OBSERVE
  Serial MRI at 12 months
  No specific treatment
            ↓
3+ features OR T1 hypointense → ACTIVE TREATMENT
  No neurological deficit → Radiation (30-40 Gy) 
                            OR Vertebroplasty (if posterior wall intact)
  With neurological deficit → Pre-op embolization + Surgery
  Surgery planned for PIVD? → Embolize hemangioma 24-48 hrs before

Key Points Specific to D5 (T5 Level)

• D5 sits in the watershed zone of spinal cord blood supply (T4-T9) - cord ischemia risk is higher here than in lumbar spine
• Aggressive hemangiomas are most commonly reported in the thoracic region - D5 is a red flag location
• Any surgical or interventional approach must account for the proximity of the Adamkiewicz artery (can arise between T5-T8 in some individuals)
• Intraoperative neuromonitoring (SSEP + MEP) is mandatory if surgery is undertaken
