The skin and superficial fascia of the anterior thigh region were cut and reflected as one layer and the pectineus, adductor longus, and gracilis muscle were exposed.
An ultrasound transducer is placed at the inguinal crease and perpendicular to the skin (Figures 1(b) and 2(a)) to identify the pectineus, adductor longus, adductorbrevis, andadductormagnusmuscles (Figure 3(a)).
As in this case, the linear probe demonstrated that the hypoechoic mass was, in fact, edematous intestine wall deep to the pectineus muscle [Figure 1]b.
Nerve to pectineus arose from the femoral nerve within the abdomen in three plexuses.
The hernia sac finally lies on top of obturator externus muscle beneath pectineus muscle.
Distinct fascicles or groups of fascicles in each compound femoral nerve represented distal nerve branches of the femoral nerve (sartorius, pectineus, medial cutaneous, saphenous, vastus medialis, vastus intermedius, vastus lateralis, and rectus femoris).
A multiloculated hydatid cyst between the iliopsoas and pectineus muscle had been diagnosed using an ultrasonography and magnetic resonance imaging (MRI).

Exercises and the respective muscle groups examined were the leg press (quadriceps femoris and gluteus maximus), knee extension (quadriceps femoris), knee flexion (hamstrings), hip abduction (gluteus medius and minimus), and hip adduction (adductor magnus, longus, and brevis, pectineus, and gracilis).
1 = gracilis muscle branch of the obturator nerve; 2 = adductor longus muscle branch; 3 = adductor brevis muscle branch; 4 = adductor magnus muscle branch; 5 = pectineus muscle branch; 6 = femoral nerve trunk.
It innervates the sartorius, pectineus, and quadriceps.
