Liver Metastasis: A Rare and Sinister Cause of Shoulder Pain

Shoulder pain is a common complaint in the elderly, the majority of which is related to musculoskeletal causes, but it can sometimes be a sign of a more sinister problem such as liver metastasis. This case report is about an elderly lady who presented with right shoulder pain, which turned out to be referred pain from liver metastasis. Clues prompting further evaluation included pain triggered by deep breathing while maintaining full shoulder mobility. This case report serves as a reminder to consider and recognise referred pain as a cause of shoulder pain, especially if range of motion and mobility are not affected.
