Schwannoma of the Lateral Femoral Cutaneous Nerve, an Unusual Cause of Meralgia Paresthetica: A Case Report

Meralgia paresthetica (MP) is a clinical syndrome usually resulting usually from compression of the lateral femoral cutaneous nerve (LFCN). Tumors arising from this nerve could also be the cause of this syndrome. We present an unusual cause of MP in a 67-year-old Caucasian male. The cause of the syndrome appeared to be a schwannoma tumor of the LFCN. Such a cause of MP has not been reported previously in the literature. Medical practitioners should also consider other causes of MP syndrome, such as peripheral nerve tumors. Although diagnosis is considered to be clinical, ultrasound or magnetic resonance imaging (MRI) could be helpful to establish the diagnosis.
