MRI Spine Analysis - Subhas Banduri, 41 years | Kolkata Medical College
Patient & Study Details
- Patient: Subhas Banduri, ~41 years
- Institution: Suraksha, Kolkata Medical College
- Modality: MRI Spine (Philips scanner)
- Film: 1 of 1 - Sagittal images of the thoracic and lumbar spine
Sequences Identified
| Row | Sequence | Key Signal Characteristics |
|---|---|---|
| Top row | T2-weighted sagittal | CSF bright (white), excellent for cord signal changes, edema, disc disease |
| Bottom row | T1-weighted sagittal | CSF dark, bone marrow fat bright - best for marrow infiltration and anatomy |
Key Pathological Findings
1. Vertebral Destruction and Collapse (Mid-Upper Thoracic - ~T5-T7)
- At least two adjacent vertebral bodies show severe destruction, fragmentation, and height loss (pathological collapse)
- On T1: Normal bright fatty marrow signal is completely replaced by hypointense (dark) signal - indicating infiltration, edema, or inflammatory/tumor replacement
- On T2: Affected vertebrae show heterogeneous hyperintensity consistent with active pathology (inflammation, fluid, or neoplastic tissue)
- The intervertebral disc space between the collapsed levels is poorly defined, narrowed, and appears destroyed
2. Epidural Mass with Severe Spinal Cord Compression
- A prominent lobulated epidural soft tissue mass extends posteriorly from the destroyed vertebrae into the spinal canal
- This causes severe spinal canal stenosis at the affected levels
- The spinal cord is severely compressed and posteriorly displaced, with the normal CSF space around the cord completely obliterated (complete CSF block)
- On T2 images, there is increased intramedullary signal at and above the compression level - indicating compressive myelopathy (cord edema or myelomalacia)
3. Paravertebral Soft Tissue Extension
- Anterior and prevertebral soft tissue thickening/mass is visible adjacent to the collapsed vertebrae
- This can represent a cold abscess (typical of tuberculosis) or aggressive tumor extension
4. Lower Thoracic and Lumbar Spine (Bottom Row)
- The lumbar spine shows disc desiccation at multiple levels (reduced T2 signal in discs), consistent with degenerative disc disease
- Disc height is relatively preserved at the lumbar levels
- No obvious lumbar cord compression is identified on these images
Differential Diagnosis
Given the pattern of adjacent vertebral body destruction, disc space obliteration, large epidural/prevertebral soft tissue mass, and the geographic context (India, 41-year-old):
| Rank | Diagnosis | Supporting Features |
|---|---|---|
| 1st | Spinal Tuberculosis (Pott's Disease) | Most common cause in India; classic involvement of 2 adjacent vertebrae with disc destruction, cold abscess, kyphotic deformity, and cord compression |
| 2nd | Metastatic spinal disease | Vertebral destruction + epidural extension, but metastases typically spare the disc until late |
| 3rd | Pyogenic spondylodiscitis | Similar imaging but usually more acute; less common to cause this degree of chronic deformity |
Clinical Significance - URGENT
This MRI demonstrates a critical finding. The patient is likely presenting with or is at high risk for:
- Paraparesis or paraplegia (bilateral lower limb weakness)
- Sensory level deficit below the compression
- Bladder and bowel dysfunction (neurogenic)
Immediate spine surgery/neurosurgery consultation is required. Management for confirmed Pott's disease typically involves anti-tubercular therapy (ATT) for 12-18 months plus surgical decompression (corpectomy, fusion) when there is neurological compromise or spinal instability.
