Doppler ultrasonography of left knee posterior side, the dotted circle is P2 segment occlusion with thrombosis formation at the popliteal artery.. Abbreviations: PA, popliteal artery; PV, popliteal vein; MHG, medial head of gastrocnemius muscle.

However, further musculoskeletal ultrasonography's transverse view of popliteal space of the posterior knee discovered the left popliteal artery was compressed by popliteus muscle and medial gastrocnemius muscle and an occlusion at the popliteal artery (as shown in Figure 1).
(A) The left knee coronal T2 with contrast MRI, (B) the popliteal artery compressed by the medial head of the gastrocnemius muscle to thicken the vessel wall.. Abbreviations: PA, popliteal artery; PV, popliteal vein; MHG, medial head of gastrocnemius muscle.

The result showed that the origin of the medial head of gastrocnemius muscle was abnormally inclined to the lateral side, and the popliteal artery was located in the medial side of the medial head of the gastrocnemius muscle (which is rarely observed) and formed an aneurysm (as shown in Figures 2-4).
The left knee sagittal T1 with contrast MRI; aneurysm formation caused by the compressed popliteal artery can be observed at the popliteal artery.

The left knee axial T1 with contrast MRI; thrombosis formation in the vessel wall of the popliteal artery can be observed.. Abbreviations: PA, popliteal artery; PV, popliteal vein; MHG, medial head of gastrocnemius muscle.
