title: In-continuity neuroma of the median nerve at the elbow.
abstract: Neuromas are a hyperplastic disorganised proliferation of cells that represent an attempt at nerve regeneration after trauma. They can be classified into terminal and in-continuity neuromas; the latter are observed when the nerve stumps are both connected. We present here the case of a 46-year-old male who sustained a deep cut at the volar aspect of the right elbow while repairing a glass. The injury caused partial transection of the median nerve, which was initially unrecognised. After several months, the patient presented pain at the volar aspect of the elbow, worsening with manual compression at the site of previous injury. Ultrasound showed an in-continuity neuroma with a hypoechoic and enlarged median nerve at the site of the sutured wound. The case report shows that ultrasound may be helpful in confirming the clinical diagnosis of neuroma and that it is useful to evaluate the percentage of the area affected by the lesion.
