Lipoma Superficial

Superficial lipomas typically appear as compressible, palpable soft-tissue masses in the subcutaneous tissue not adherent with the overlying skin. Lipomas have a male and familial predominance and tend to grow in the hack, shoulder and upper arms with a predilection for the extensor surface. They are more common in the fifth and sixth decades. Although lipomas most often present as a solitary...

Fig. 8.79a,b. Lipoma in a patient with painless soft-tissue swelling over the anterior elhow. a Transverse 10-5 MHz US image over the distal humerus with b Tlw GRE MR imaging correlation demonstrates an oval hypoechoic soft-tissue mass (L) located superficial to the hrachialis muscle (br) that displaces the hrachial artery (a) and the distal hiceps tendon (arrows). In this particular case, the echotexture of lipoma is quite similar to the underlying hrachialis and should not be interpreted as a normal muscle. Asterisk, medial edge of the humeral trochlea... 

Diagnosis of superficial lipomas is usually straightforward. In deep-seated or intramuscular masses, the identification of the lipomatous mass may be more difficult with US due to a similar appearance with adjacent muscles (Fig. 11.70). In such cases, a fidl knowledge of the muscular anatomy of the palm and the comparative evaluation of the opposite hand may be helpful for the conclusive diagnosis.
