Educational Pearls:
- Lateral Cutaneous Femoral Nerve Entrapment Syndrome, also known as Meralgia Paresthetica, results from entrapment of the lateral cutaneous femoral nerve, often as it exits the pelvis under the inguinal ligament.
- Meralgia Paresthetica is associated with obesity, pregnancy, compression from clothing or belts and diabetes.
- Symptoms include numbness, paresthesia and pain of the proximal lateral thigh. Signs or symptoms of radiculopathy such as weakness, loss of reflexes or severe back pain should not be present.
- Diagnosis is clinical and does not require further imaging if there are no additional or concerning findings.
- Meralgia Paresthetica typically resolves over time without intervention; however patients should be counseled on weight loss, diabetes control and avoidance of compressive clothing as relieving factors.
