Meralgia Paresthetica (MP) is a condition characterized by discomfort, numbness, and tingling sensations in the outer thigh, resulting from compression or injury to the Lateral Femoral Cutaneous Nerve (LFCN). This nerve provides sensory innervation to the outer aspect of the thigh and is often impinged beneath the inguinal ligament, leading to sensory impairment in its distribution area. While compression of the LFCN is a well-known cause of MP, the occurrence of LFCN neuromas as a causative factor is quite rare. This case report presents a distinctive instance of Meralgia Paresthetica resulting from an LFCN neuroma, contributing to a deeper understanding of the condition.
The patient’s symptoms were carefully assessed, and the diagnosis was confirmed using ultrasound imaging, which demonstrated the presence of a neuroma on the LFCN. This case highlights the importance of considering neuromas in the differential diagnosis of Meralgia Paresthetica, particularly in patients who may not respond to conventional treatment for LFCN compression. By documenting this unique presentation, we aim to enhance awareness among healthcare professionals regarding the potential for LFCN neuromas to cause symptoms consistent with MP. This case underscores the necessity for thorough evaluation and consideration of rare etiologies in patients presenting with outer thigh discomfort, numbness, and tingling. Ultimately, increased recognition of LFCN neuromas can lead to improved diagnostic accuracy and treatment options for affected patients, enhancing their quality of life.
