Figure 1. Preoperative magnetic resonance image of the right knee. Sagittal T1-weighted image (a), sagittal T2-weighted image (b), coronal T2-weighted image (c), and axial T2-weighted image (d) reveal a mass in the gastrocnemius medialis muscle, which does not communicate with the articular joint.
Figure 2.
Figure 2. Intra-operative cyst located in the gastrocnemius medialis muscle (a) and partial tissue of the excised cyst (b), as the cyst ruptured partly when excised.
Figure 3.
Figure 3. Preoperative magnetic resonance image (MRI) of the right knee. Sagittal T1-weighted image (a), sagittal T2-weighted image (b), coronal T2-weighted image (c), and axial T2-weighted image (d) reveal a mass in the gastrocnemius lateralis muscle. Thickened synovium with low signal intensity on both T1-weighted and T2-weighted images is found in the knee joint.

Figure 4. Preoperative magnetic resonance image (MRI) of the right knee. Sagittal T2-weighted image showed the cyst wall to be attached to the knee joint capsule.
