From: Popliteal cysts and subgastrocnemius bursitis are associated with knee symptoms and structural abnormalities in older adults: a cross-sectional study

Figure 1

Simultaneous presence of a popliteal cyst (Baker cyst) and subgastrocnemius bursitis in a right knee. A grade-3 popliteal cyst (arrow) was superficially located adjacent to the medial head tendon of the gastrocnemius (A); also a grade-3 subgastrocnemius bursitis (arrow) was shown between the capsule and medial head of the gastrocnemius (B); the popliteal cyst and subgastrocnemius bursitis were separated but communicated with each other in the multiplanar view in the sagittal plane (C).
