Sonoanatomy of the lateral femoral cutaneous nerve. Short-axis views of the lateral femoral cutaneous nerve at different levels along the thigh. A At the anterior superior iliac spine, the nerve is typically seen running medial to the ASIS which is used as the landmark to identify the nerve. B Just distal to the ASIS, the nerve is seen running under the subcutaneous tissue. C At the proximal thigh, the nerve can be identified running in a small lacunar-like compartment formed by the superficial fascia lata and the deeper fascia iliaca. D Further distally at the thigh, the nerve is seen dividing into two terminal branches
