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.

Hamstring Conjoint ​Tendon Complete Rupture

about ultrasound, mri and thermography findings of hamstring conjoint complete tear

Today I show you the clinical case of a professional long-distance runner that felt a moderate pain at the proximal posterior side of his right thigh, after a city marathon. The patient came for first to perform an ultrasound exam.

When the injury involves only the tendinous component, less hematoma can be found, so pay attention when you perform the ultrasound examination; the elastosonography exam can help you, in this case, working like a “contrast agent” better depicting the site of injury.

I suggest you always to perform both MRI and ultrasound exams to establish the real amount of the injury.

And what’s about the thermography examination? A clear asymmetry of the skin temperature is evident in the site of injury, with the right thigh 3.4 °C colder than the left side.
