OBJECTIVE: To describe clinical and sonographic features of confirmed intraneural perineurioma in 5 patients.
MATERIAL AND METHODS: We report clinical and sonographic features and retrospective follow-up data in 5 patients with intraneural perineurioma verified by biopsy.
RESULTS: In all cases, symptoms were represented by a slowly progressive painless mononeuropathy with muscle atrophy and impaired tendon reflexes. Ultrasound examination revealed locally enlarged cross-sectional area of the nerve that was confirmed by intraoperative visualization.
CONCLUSION: Intraneural perineurioma should be obligatory suspected in case of fusiform thickening of the nerve with locally changed echogenicity. Pooled multiple-center studies with large samples are needed to determine sensitivity and specificity of the main ultrasound parameters including changes in cross-sectional area and echogenicity of the nerve.
