Overview
Distal biceps tendinosis is a chronic degenerative condition characterized by collagen disorganization, mucoid degeneration, and tenocyte hypertrophy. Unlike tendinitis, which implies an acute inflammatory process, tendinosis reflects a failed healing response to repetitive microtrauma and mechanical overload.
1. Signal Characteristics
Key Concept:
Tendinosis alters tendon signal intensity without macroscopic fiber disruption.
- T1-weighted & PD-weighted images
- T2-weighted images
2. Morphological Alterations
Hallmark Feature: Tendon Thickening
- Tendon Enlargement
- Contour Irregularity
- Internal Architecture
3. Associated MRI Findings
- Bicipitoradial Bursitis
- Insertional Changes (Enthesopathy)
4. Clinical Relevance & Reporting Pitfalls
- High Incidental Prevalence
- Critical Reporting Principle
- Prognostic Significance
Take-Home Message
Distal biceps tendinosis on MRI reflects chronic degeneration rather than inflammation. Accurate interpretation requires careful assessment of signal changes, tendon morphology, associated bursitis or enthesopathy, and—most importantly—clinical correlation to avoid overdiagnosis while recognizing rupture risk.
