Multiple schwannomas of the median nerve: a case report and literature review

Abstract

We report a case of multiple schwannomas of the median nerve. Multiple schwannomas can be difficult to diagnose on clinical grounds and can be mistakenly diagnosed as carpal tunnel syndrome or ganglia as in our case. Nerve conduction studies helped locate non-visible tumours. Magnetic resonance imaging (MRI) is useful in the preoperative planning of these tumours. The appearances on scanning however can be sometimes confused for ganglia as in this case. Intraneural dissection of the schwannomas was carried out and the pathology is described.
