Sonographic analysis of the ankle in patients with psoriatic arthritis.

Foot involvement is very frequent in patients affected by psoriatic arthritis (PsA). However, evaluation of the painful foot can be problematic, because it is often difficult to distinguish between arthritis, tenosynovitis, and enthesopathy. Plain radiographs can show bone erosion or other features of joint involvement, but give little information about the soft tissues.

[Hematoma and fat necrosis of the breast: mammographic and echographic features].

The mammary gland is a common site for traumas which often lead to the formation of intraglandular hematomas. The abundance of fat tissue in this gland accounts for the relatively high frequency of fat necrosis and self-digestion of fat by lipases after traumas, i.e.

[Echography in the study of lipomas of superficial soft tissues].

High-resolution sonography (US) was used to evaluate 47 superficial soft tissue lipomas. Forty-one lesions were found in subcutaneous tissues and 6 in superficial muscles. The lipomas were classified by location, shape, echotexture, homogeneity and US beam attenuation values.
