A 64year old man presented with vomiting and colicky right upper abdominal pain radiating to his back. He had had these symptoms intermittently for three months, but they had acutely worsened over the last three days. He had undergone a total nephrectomy for a right sided renal tumour six years ago but had subsequently discharged from oncology follow-up. There was no other relevant past medical history.
