We report an unusual presentation in an elderly woman with a previous diagnosis of benign tremulous Parkinson’s disease who developed a severe Parkinsonian-like syndrome with profound immobility following small bowel resection. Her Parkinsonism was largely unresponsive to conventional medical therapy. However, she was found to be profoundly hypomagnesaemic and a dramatic improvement in her symptoms and functional ability was achieved after correction of the severe hypomagnesaemia. A brief discussion is included.
