MRI ADHESIVE CAPSULITIS IGHL FROZEN SHOULDER (VIDEO)
MRI SHOULDER ADHESIVE CAPSULITIS IGHL
MRI FINDINGS OF ADHESIVE CAPSULITIS ALSO KNOWN AS FROZEN SHOULDER
- In this post we look at the MRI Frozen Shoulder / MRI Adhesive Capsulitis.
- Frozen Shoulder or Adhesive capsulitis on MRI is a common abnormality but is often missed because we don’t specifically look there.
- This condition involves the IGHL so it’s important to know the normal IGHL MRI appearance and where to look for it.
- So, what are the MRI findings of a normal IGHL and Adhesive Capsulitis?
- This 1-minute video below looks at the normal appearance of the IGHL and how it changes in Adhesive Capsulitis / Frozen Shoulder. Where to look for it and how to diagnose it.

TEST YOURSELF ON SOME COMMON & FREQUENTLY ASKED QUESTIONS
WHAT IS THE NORMAL APPEARANCE OF THE IGHL ON A PROTON DENSITY (PD) SCAN?
Black, thin, and well-defined.
WHICH LIMB OF THE IGHL IS TYPICALLY THICKER IN NORMAL ANATOMY?
The Anterior limb is thicker than the posterior limb.
WHAT IMAGING CHARACTERISTICS INDICATE IGHL CAPSULITIS ON A PD FAT-SAT SCAN?
Thickened, hyperintense, and ill-defined IGHL.
Capsulitis causes ligament thickening, increased signal (hyperintensity), and loss of crisp margins due to inflammation and edema.
WHY IS THERE REDUCED CONTRAST BETWEEN THE IGHL AND MUSCLE IN IGHL CAPSULITIS?
Because the IGHL signal intensity approaches that of muscle.
In capsulitis, the IGHL’s hyperintense signal approaches muscle intensity, making the two less distinguishable.
WHICH MRI SEQUENCE IS SPECIFICALLY MENTIONED AS USEFUL FOR EVALUATING IGHL CAPSULITIS?
PD fat-saturated scan.
