An unusual presentation of multiple myeloma.

The authors report a case of a 58-year-old woman, ex-smoker, who was referred to the respiratory clinic with a presumed unresolving airspace shadowing in the right lung. Further evaluation of the shadowing with a CT thorax revealed rib lesions, a pancreatic lesion and multiple liver lesions, making the diagnosis of metastatic pancreatic carcinoma most likely. However, further blood investigations and imaging eventually revealed the cause for the shadowing to be multiple myeloma, since the unresolving shadowing was actually a rib lesion.
