A variety of solid and cystic masses can be encountered around the knee as incidental findings. Most are benign, have an indolent behavior, such as lipomas, synovial and ganglion cysts, bursitis and neurogenic tumors, and can be easily diagnosed with US based on previously described criteria (Fig. 12.135). In the knee, however, there are some specific masses which merit particular attention. These include the lipoma arborescens and pigmented villonodular synovitis. In addition, an accessory muscle, the tensor fasciae suralis, can present as a pseudomass arising on the posterior aspect of the knee and warrants additional brief discussion here.
