case_images: Computerized tomography (CT) - angiography of the popliteal fossa in 4-mm sections showed a popliteal artery stenosis with a post-stenotic dilatation (Figure 1).
case_images: magnetic resonance angiography (MRA) of the popliteal fossa showing (A) the stenotic segment of the popliteal artery (arrow), notice the decreased blood flow downstream; (B) the abnormal musculotendinous insertion of the medial gastrocnemius head (arrow)

case_images: We note that an atheroma plaque of 14 mm was also found reducing partially the popliteal artery lumen with a low flow downstream (Figure 2).
case_images: operative photos showing (A) the anomalous accessory slip of the medial head of the gastrocnemius muscle (arrow) and (B) the post-stenotic popliteal aneurysm after resection of the anomalous muscle

case_images: An abnormal insertion into the medial femoral condyle of the accessory head of the gastrocnemius muscle was found (Figure 3).

case_images: An autologous saphenous venous graft was used to replace the compromised arterial segment, and the accessory head the gastrocnemius muscle was resected (Figure 4).

case_images: An angiographic control (Figure 5) allowed confirmation of the stenosis relief and the restitution of a good blood flow.
