摘　　要：目的探讨高频超声对外周神经内神经束膜瘤的诊断价值。方法回顾性收集2015年6月至2022年6月于山东第一医科大学附属省立医院经手术或活检证实的11例外周神经内神经束膜瘤患者,均行高频超声检查,收集患者临床资料和超声表现,分析其声像图特征,记录受累神经的最大横截面积,并与对侧肢体相应位置比较。结果11例外周神经内神经束膜瘤均为单一神经病变,声像图表现为受累的神经呈梭形增粗,增粗的神经束膜瘤最大横截面积与对侧肢体相应位置比较差异有统计学意义[(0.158±0.043)cm比(0.044±0.012)cm,t=8.669,P<0.001],受累神经内部神经束增粗,增粗的神经束与周围的纤维结缔组织分界模糊,但仍可见神经束之间高回声线状分隔,部分病灶内可见钙化;彩色多普勒血流显像示增粗的神经内可见点条状血流信号。结论高频超声是诊断外周神经内神经束膜瘤有价值的影像学检查方法。Objective To investigate the value of ultrasound in the diagnosis of intraneural perineurioma.Methods From June 2015 to June 2022,11 patients with intraneural perineurioma confirmed by surgery or biopsy in Provincial Hospital Affiliated to Shandong First Medical University were retrospectively collected,all of whom underwent high-frequency ultrasound examination.Clinical data and sonographic characteristics were collected.The maximum cross-sectional area of the affected nerve was recorded and compared with the corresponding site of the contralateral nerve.Results All the 11 cases of intraneural perineurioma were single neuropathy.The sonogram showed that the affected nerve was spindle shaped and thickened.There was a statistical difference between the maximum cross-sectional area of the thickened intraneural perineurioma and the corresponding site of the contralateral nerve[(0.158±0.043)cm vs(0.044±0.012)cm,t=8.669,P<0.001].The fascicles of the affected nerve were thickened with loss of normal fascicular definition,but there were still hyperechoic linear separation among the fascicles.Conclusions High-frequency ultrasound may be a valuable technique for the diagnosis of intraneural perineurioma.
