Core Tip

Core Tip: Schwannoma is a benign slowly growing tumor which is most common in the central nerve system. Peripheral schwannomas can give symptoms as numbness, local- and radiating pain. Recent studies proves surgical excision can be made with low expectations for complications and a high rate of remission. Never the less, some patients show up with consisting and significant symptoms after surgery. Our study showed that location of tumor on the nerve is of importance when evaluating patients’ clinical symptoms post-operatively.
