Answer

Ultrasonography can facilitate the diagnosis of pes anserine bursitis. [26, 27] Large, cystic bursal swellings have been identified by means of ultrasonography and computed tomography (CT). However, published reports suggest that in most suspected cases, ultrasonographic findings are lacking. [28] This lack of ultrasonographic findings has led some to question the frequency of pes anserine bursitis and its accepted pathophysiology.

In one study, only 3 of 29 patients with suspected pes anserinus tendinobursitis were found to have tendinitis on ultrasonographic images when compared with the uninvolved extremity or healthy controls. [28] In a study of patients with type 2 diabetes mellitus, 4 out of 14 patients who were clinically diagnosed with pes anserine tendinobursitis syndrome were found to have ultrasonographically apparent morphologic changes in the pes anserine tendons.
