An 85-year-old woman presented to the emergency department for evaluation of gradually worsening upper back pain of 3 weeks’ duration. Her pain radiated down her right arm and was associated with right arm weakness. She reported visiting pain medicine specialists who administered steroid and lidocaine injections, which failed to improve her symptoms. Initial CT of her chest revealed a large lytic lesion within her posterior right fourth rib extending into her T4 vertebral body. The primary malignancy, a mucinous cystadenocarcinoma of the pancreas, was later found on a CT of the abdomen. The patient was also found to have multiple pulmonary, hepatic and lymphatic metastases from the pancreatic primary tumour.
