Abstract:
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.
