There is a lot written about acetabular labral tears but there are other abnormalities of the labrum that can be precursors to or associated with tears. Here we look at Mucoid Degeneration.
Mucoid degeneration of the acetabular labrum is not uncommon, but Ive not been able to find too much written about it apart from passing references to it in articles dealing with the labrum.
MRI MUCOID DEGENERATION: SOME BACKGROUND
- The MRI findings are T2/PD hyper-intensity and enlargement of the labrum which can be focal or diffuse.
- Intra labral cysts can also develop.
- We see it more often in the anterosuperior and superolateral labrum
- The MRI changes are similar to mucoid degeneration of other structures like the ACL or degeneration that can occur in a discoid meniscus.
- Mucoid degeneration can occur in an otherwise normal labrum or in dysplastic labrums associated with acetabular dysplasia.
We look at all of these topics in more detail in our HIP MRI Mini Fellowships.
