Dynamic Ultrasound Study of the Quadriceps Muscle

It is always interesting to study the functionality of the muscles in real training conditions; in this period I am testing the usefulness of the ultrasound study performed during walking and running on the treadmill.

What is evident is a difference from the conventional examination in terms of shape and dimensions of the various muscle components, which work as a single entity.

In this study, I’m using a MyLab 9 ultrasound device from Esaote, with an external accessory called Probe-Fix which provides lengthy and stable fixation of the probe to the body.

In the video, you can see the quadriceps muscle study, but I’m also testing the hamstrings in the same conditions and during other physical activities, such as squatting and jumping.

Enjoy the video and stay tuned.

Common Peroneal Nerve Schwannoma

Palpable mass on the lateral side of the popliteal fossa.

The mass is characteristically eccentric with respect to the affected nerve, and the nerve is displaced to the periphery of the mass. 

The ultrasound picture allows us to distinguish the internal structure of the lesion accurately and study the entire course of the nerve. 

The histologic architecture of the mass is with more myxoid material peripherally and more fibrous tissue centrally. 

The study with elastosonography shows the different structural characteristics of the various components of the mass, distinguishing between the “softer” mixoids and the “harder” fibrous ones.

My suggestion is always to combine MRI and ultrasound examinations to define these kinds of lesions better.
