Abstract:
In this retrospective study, we analysed the clinical features of neurilemoma when it is located in muscle. Twelve patients had an intramuscular neurilemoma as shown on magnetic resonance (MR) scans and confirmed at operation. In six it was located in the upper limb, in five in the lower limb, and in one in the back. The mean age of the patients was 41 years (12 to 58). Nine complained only of a palpable mass and the other three of a mass with slight tenderness. None had neurological symptoms or signs, such as radicular pain, a positive Tinel sign, or motor weakness. There were no postoperative complications or recurrence of the tumour after a mean follow-up of two years (1 to 10).
