Coronal T1 (A), sagittal fat-suppressed T2 (B), and axial fat-suppressed T2 (C) images demonstrate a 8x 6mm ovoid focus (arrows) in the popliteal tendon consistent with a cyamella demonstrating bone marrow edema. There is popliteal myotendinous and pericapsular edema consistent with posterolateral corner injury.

Multiplanar, multisequence MRI evaluation of the right knee was performed, including axial, coronal, and sagittal fat-suppressed T2 sequences and coronal T1 and sagittal proton-density sequences, as shown below (Figure 1, Figure 2).
Sagittal proton-density image (A) and coronal T1 image (B) demonstrate a cyamella with marrow edema in the popliteus tendon.
