metastasis ( RID5231 ) Let this be a cautionary tale, not to accept non-diagnostic quality images. Not that clinical outcome will be affected. Initial fracture looked traumatic and seemed to heal. Id not seen the chest CT until I got the f/u MRI yesterday. Diagnosed with lung cancer by CT last week, the humeral lesion was missed on the CT (could have spared him the return for the MRI). Probably visible in retrospect on the utterly lousy shoulder radiographs in slide 1.
