[Struma as a cause of a brachialgia]

A 76-year-old woman with a great multi-nodular goitre and no neurological deficits suffered from increasing pain of the lateral upper arm. A combination of nerve blockades and physical measures was not effective in terms of continuous pain control. Subtotal thyroidectomy resulted in a long-term complete pain relief. The underlying mechanism is explained as a compression of the superior trunk of brachial plexus by a goitre. In future a goitre should be taken into consideration in the aetiology of a brachialgia.
