In the popliteal region on the left, a heterogeneous an-/ hyperechoic inclusion, similar to a complex cyst, without blood flow, without clear boundaries with the muscle, up to 17 x 6 x 21 mm in size is visualized (differential diagnosis: intramuscular hematoma / partial rupture of the muscle, etc. ).
In the popliteal region on the right, an anechoic inclusion with a clear contour, without blood flow, up to 47 x 9 x 26 mm in size is visualized (differential diagnosis: Baker's cyst, etc.)
