Right forearm mass. Suspect lipoma. Evaluate for nature of mass. A marker was placed along the radial aspect of the proximal forearm. Deep to this marker is a fatty mass centered in the mid forearm between the brachioradialis and extensor carpi radialis longus muscles. The mass is approximately 4.7 x 2.4 cm in transverse dimension and approximately 10 cm in longitudinal dimension. It displaces the brachioradialis muscle laterally. The radial artery and what I believe to be the superficial branch of the radial nerve course along the anterior margin of the mass. A couple of thin septations traverse the mass but I see no dominant nonadipose element. Osteoarthritis affects the elbow and wrist.
Forearm lipoma as above.
