“…Starting proximal, Rinkel et al reported a case of meralgia paresthetica caused by compression of the nerve root L2 by a metastatic tumor of vertebral body L2 [ 43 ]. Other causes of L2 root compression included (extraforaminal) disc herniation of L2–L3 [ 44 – 46 ] and a schwannoma of L2 [ 47 ]. More distal causes were a uterine fibroid tumor compressing the superior lumbar plexus [ 48 ], a malignant tumor in the psoas [ 49 ], a retroperitoneal lipofibrosarcoma [ 50 ], a renal tumor [ 51 ], a pancreatic pseudocyst [ 52 ], an abdominal aortic aneurysm [ 53 ], a metastasis of the iliac crest [ 54 ], a synovial cyst in the iliac fossa [ 55 ] and a hematoma of the iliac muscle [ 38 ].…”

“…In our surgical series we found 4 cases of compression of the LFCN, including two cases of schwannoma, one case of lipoma and one case of endometriosis. A few other cases of schwannoma involving the LFCN have been described in the literature: one case involving the LFCN [ 66 ] and one intradural case at the level L2 [ 47 ]. Also compression of the LFCN by a lipoma has been described previously [60 61]: one case was treated surgically [ 60 ] and one case by injection of triamcinolone and lidocaine [ 61 ].…”

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.

“…Schwannoma is characterized by a slow-growth creating a capsule, which consists of the perineurium of the nerve bundle of origin, surrounded by a condensation of the deepest layers of the epineurium, around well differentiated Schwan cells [1] , [15] . On the other hand, schwannoma may remain asymptomatic until the mass has compressed a subjacent neurovascular bundle [2] , [16] . In our case, the patient had a small schwannoma with a misleading symptomatology which mimic a sciatic L5 leading to delay of diagnosis of 18 months.…”

Introduction Schwannoma is the most common benign nerve sheath tumor. Peripheral nerves of the lower extremity are rarely involved and usually asymptomatic. Case presentation We report the case of a misleading clinical presentation of lateral sural cutaneous nerve schwannoma. Discussion To the best of our knowledge, no case has been reported about the location of schwannoma in the lateral sural cutaneous nerve. MRI and anatomopathologic assessment, after microscopic enucleation, are required to confirm diagnosis. Conclusion Care must be taken to not miss a schwannoma of lateral sural cutaneous nerve by meticulous clinical examination and appropriate imaging using MRI in unexplained L5 sciatica.

“…The symptoms depend on the location, with radiculopathy being the most frequent initial symptom, followed by paresthesia and limb weakness. 10 When large nerves are affected, the tumor has characteristically eccentric growth, and the nerve is displaced toward the periphery. Clinically, Schwannomas can mimic a lipoma or a ganglion at the skin level.…”

Peripheral Nerve Schwannomas: A Literature Review

et al. 2019

View full text Add to dashboard Cite

Introduction Schwannomas are benign tumors originating from the cells, which wrap around axons that are usually encapsulated and solitary. These tumors usually lead to little or no symptomatology. They are usually the most common peripheral nerve tumors in adults, with their highest incidence between the third and fifth decades of life. Objective To perform a review about schwannoma of the peripheral nerves, presenting its definition, epidemiology, diagnosis, symptomatology and treatment. Methodology This is a descriptive work, based on a review of articles available in the PubMed database with the descriptors schwannoma and peripheral nerves. Results and Discussion Only papers published between 1981 and 2019, describing studies in humans, and that were available as full articles were selected. A total of 391 articles were included; after reading the titles, we noted that 67 articles fit the topic of the present study. Among the articles selected for reading, 33 fit the objectives of the present work, and were considered for the writing of the present article. Conclusion Schwannomas are benign myelin sheath tumors that develop with local symptomatology or asymptomatic and present a good surgical prognosis with generally reduced rates of surgical complications.
