“…MP, originally known as the Bernhardt-Roth syndrome, was first described by Bernhardt and Roth in 1895. 3 The term was coined from the Greek words "meros"-thigh and "algos"-pain. By definition, MP is a neurological disorder resulting from compression of the LFCN, a purely sensory branch of the L2/L3 nerve root as it crosses between the ASIS and the inguinal ligament, while entering the thigh.…”

“…The symptoms may relieve with weight loss, abdominal exercises, or childbirth, but they may also worsen with walking or prolonged standing. 2,3 In patients who do not respond to oral treatment, regional LFCN nerve block is common recommended as an effective MP treatment. However, anatomical diversity leading to failure rates for regional nerve blocks.…”

Meralgia paresthetica (MP) or so-called as lateral femoral cutaneous nerve (LFCN) entrapment is a mononeuropathy characterized by a localized area of paresthesia, dysesthesia, tingling, burning, and numbness on the anterolateral aspect of the thigh, between the inguinal ligament and the knee without associated loss of reflexes and motor weakness. The incidence of MP increases with obesity and diabetes. Ultrasound-guided has been demonstrated useful for visualization of peripheral nerves, in particular very small nerves such as the LFCN. Hereby, we reported a case of 63-year-old man diagnosed with MP. The patient complained of numbness, and no pain when pinched in his anterolateral aspect of the left thigh since 3 weeks ago. On physical examination, his body mass index (BMI) was 27 (overweight) with normal vital signs. Neurological examination revealed normal motoric function and refleks; but decreased sensation to pinprick in the left anterolateral thigh in the LFCN distribution. No abnormal findings on plain radiographs of the pelvis and lumbar spine. Ultrasound-guided injection was performed in this patient.

“…This can be remedied by fanning the probe such that the nerve becomes hyperechoic on the screen. 3 , 5 In cases of entrapment, the nerve may be a larger diameter than the unaffected side or have a more hypoechoic appearance of the fascicles. The ultrasound transducer can also be used to provoke a Tinel sign (elicitation of symptoms with palpation of the nerve) similar to sonographic Murphy’s sign in cholecystitis.…”

Introduction: Neuropathy of the lateral femoral cutaneous nerve, also known as meralgia paresthetica, causes pain and paresthesia to the anterolateral thigh. It commonly results from nerve irritation from extrinsic compression; however, it may occur spontaneously. Symptoms from this condition can be debilitating, and the pain may be ascribed to other conditions leading to delays in diagnosis. Peripheral nerve blockade can be useful both diagnostically and therapeutically for meralgia paresthetica.Case Report: Two female patients in their sixties presented to the emergency department for chronic, atraumatic, left upper thigh pain. In both cases the patients had hyperalgesia and paresthesia to the anterolateral, upper thigh. The emergency physician performed an ultrasound-guided nerve block of the lateral femoral cutaneous nerve for each patient, which resulted in temporary, complete resolution of their pain. Conclusion: Meralgia paresthetica is an uncommon but painful condition that can elude diagnosis. Physical exam findings such as allodynia and hyperalgesia of the anterolateral thigh in the absence of back pain is suggestive of the diagnosis. Utrasound-guided nerve blockade can be helpful to the emergency physician to confirm the diagnosis and provide non-opioid pain relief to the patient.

“…The lateral femoral cutaneous nerve (LFCN) is a sensory nerve that originates from the lumbar plexus L2/L3, which is characterized by high anatomic variability, especially at the level of the inguinal ligament and the anterior superior iliac spine. (50,51) Meralgia paresthetica is a disorder related to the entrapment of the LFCFN. Patients usually complain of burning pain and/or dysesthesia located at the anterolateral thigh, which may radiate to the knee.…”

“…Obesity, diabetes mellitus, pregnancy, and advancing age are associated risk factors. (51,52) The course of the LFCN is very superficial and thus, it is susceptible to irritation resulting from, e.g., too tight clothing, especially in obese patients. Moreover, at the site where the LFCN pierces the fascia lata, it may become damaged by a tension mechanism (abrupt hyperextension of the hip) or a compression mechanism (long standing position).…”

Nerve entrapment syndromes are commonly encountered in clinical practice. Accurate diagnosis and management require knowledge of peripheral neuroanatomy and recognition of key clinical symptoms and findings.Nerve entrapment syndromes are frequently associated with structural abnormalities of the affected nerve. Therefore, imaging allows for the evaluation of the cause, severity, and etiology of the entrapment. High resolution ultrasonography can depict early and chronic morphological changes within the entire nerve course and is therefore an ideal modality for the diagnosis of various nerve entrapment syndromes at different regions. This review article presents some of the most common nerve entrapments, with special focus on ultrasound imaging and key findings.
