Variations in the anatomy of the lateral femoral cutaneous nerve (LFCN) have been reported in the literature. LFCN is vulnerable to injury during several surgical operations, therefore any surgeon intervening in the area should be familiar to its topographic variability. Lesion of the nerve leads to a condition known as "meralgia paresthetica". We present a cadaveric case of a variant LFCN where two LFCN branches were encountered arising from the lumbar plexus. In specific the anterior LFCN branch originated from the femoral nerve, whereas at the level of the inguinal ligament, four nerve branches were present. The existence of multiple LFCN branches could lead to diagnostic confusion in case of "meralgia paresthetica", while if the neurosurgeon is not aware of the potential variability during surgical decompression of the nerve, postoperative complications may occur. The supernumerary LFCN branches could be identified by ultrasound imaging and be used as optimum vascularized grafts for sensory nerve repair.
文献中已报道了股外侧皮神经（LFCN）解剖结构的变异情况。LFCN在多种外科手术过程中易受损伤，因此任何在此区域进行手术的外科医生都应熟悉其解剖变异情况。该神经损伤会导致一种称为“感觉异常性股痛”的病症。我们展示了一例LFCN变异的尸体病例，其中发现两条LFCN分支发自腰丛。具体而言，前LFCN分支起源于股神经，而在腹股沟韧带水平有四条神经分支。LFCN多分支的存在可能会在“感觉异常性股痛”病例中导致诊断混淆，并且如果神经外科医生在对该神经进行手术减压时未意识到潜在的变异情况，可能会发生术后并发症。额外的LFCN分支可通过超声成像识别，并用作感觉神经修复的最佳带血管移植物。
