“…In addition, multiple causes of LFCN compression have been reported around the SIAS, including hemangiomatosis [ 56 ], heterotopic ossification [ 57 , 58 ] and a pelvic osteochondroma [ 59 ]. Finally, multiple distal sites of compression have been found to cause symptoms of meralgia paresthetica including lipoma/lipomatosis [ 60 , 61 ], fibrosis of the sartorius muscle [ 62 ], inguinal lymphadenopathy [ 63 ], femoral acetabular impingement [ 64 ], giant hemorrhagic trochanteric bursitis [ 65 ] and a schwannoma inside the LFCN [ 66 ]. Besides cases with a cause of compression along the course of the LFCN, also cases have been reported on more diffuse compression by increased intra-abdominal pressure: one bilateral case due to pelvic inflammatory disease [ 67 ] and one case after peritoneal dialysis [ 68 ].…”

Unusual causes for meralgia paresthetica: systematic review of the literature and single center experience

et al. 2023

Meralgia paresthetica is often idiopathic, but sometimes symptoms may be caused by traumatic injury to the lateral femoral cutaneous nerve (LFCN) or compression of this nerve by a mass lesion. In this article the literature is reviewed on unusual causes for meralgia paresthetica, including different types of traumatic injury and compression of the LFCN by mass lesions. In addition, the experience from our center with the surgical treatment of unusual causes of meralgia paresthetica is presented. A PubMed search was performed on unusual causes for meralgia paresthetica. Specific attention was paid to factors that may have predisposed to LFCN injury and clues that may have pointed at a mass lesion. Moreover, our own database on all surgically treated cases of meralgia paresthetica between April 2014 and September 2022 was reviewed to identify unusual causes for meralgia paresthetica. A total of 66 articles was identified that reported results on unusual causes for meralgia paresthetica: 37 on traumatic injuries of the LFCN and 29 on compression of the LFCN by mass lesions. Most frequent cause of traumatic injury in the literature was iatrogenic, including different procedures around the anterior superior iliac spine, intra-abdominal procedures and positioning for surgery. In our own surgical database of 187 cases, there were 14 cases of traumatic LFCN injury and 4 cases in which symptoms were related to a mass lesion. It is important to consider traumatic causes or compression by a mass lesion in patients that present with meralgia paresthetica.

“…1 Previous studies by our group have reviewed subsets of femoral nerve injury, including the pathophysiology of lateral femoral cutaneous neuropathy and femoral predominance in lumbosacral radiculoplexus neuropathy. [2][3][4][5][6][7][8][9] Given the paucity of recent studies specifically exploring femoral neuropathy, and the significant morbidity that may ensue, we aimed to perform a comprehensive retrospective study to gain a better understanding of femoral neuropathy via assessment of risk factors, etiologies, electrodiagnostic (EDx) features, and clinical course.…”

Introduction/AimsFemoral neuropathies can cause severe, prolonged debility, yet there have been few clinical and electrodiagnostic (EDx) studies addressing this condition. The aim of this study was to better understand the etiologies, EDx features, and clinical course of femoral neuropathy.MethodsWe identified patients evaluated at Mayo Clinic Rochester between January 1, 1999 and July 31, 2019, with possible new femoral neuropathy ascertained via International Classification of Diseases‐versions 9 and 10 diagnosis codes presenting within 6 months of symptom onset.ResultsA retrospective review of 1084 records was performed and we ultimately identified 159 patients with isolated femoral neuropathy for inclusion. The most common femoral neuropathy etiologies were compressive (40%), perioperative stretch (35%), and inflammatory (6%). Presenting symptoms included weakness (96%), sensory loss (73%), and pain (53%). Presenting motor physical exam findings demonstrated moderate weakness (34%) or no activation (25%) of knee extension and mild (32%) or moderate (35%) weakness of hip flexion. Seventy‐two percent of patients underwent EDx testing, including 22 with femoral motor nerve conduction studies. Treatment often involved physical therapy (89%) and was otherwise etiology‐specific. In patients with follow‐up data available (n = 154), 83% had subjective clinical improvement at follow‐up with a mean time to initial improvement of 3.3 months and mean time to recovery at final follow‐up of 14.8 months. Only 48% of patients had nearly complete or complete recovery.DiscussionIn our cohort, the most common etiologies of femoral neuropathy were compression or perioperative stretch with high initial morbidity. Although motor recovery is common, improvement is often prolonged and incomplete.

“…SSEPs have also been shown to be useful in diagnosing diseases that affect mainly the peripheral nervous system, such as chronic inflammatory demyelinating polyneuropathy 32,33 , Guillain-Barré syndrome 34 , mononeuropathy 35,36 , Charcot-Marie-Tooth disease 37 , diabetic neuropathy 38 and polyneuropathy 39 . SSEPs complement sensory nerve conduction tests in general, and assessment of proximal sensory fibers in particular, and they are especially helpful in demonstrating proximal neuropathic involvement.…”

The authors present a review of the current use of somatosensory evoked potentials (SSEPs) in neurological practice as a non-invasive neurophysiological technique. For this purpose we have reviewed articles published in English or Portuguese in the PubMed and LILACS databases. In this review, we address the role of SSEPs in neurological diseases that affect the central nervous system and the peripheral nervous system, especially in demyelinating diseases, for monitoring coma, trauma and the functioning of sensory pathways during surgical procedures. The latter, along with new areas of research, has become one of the most important applications of SSEPs.
