History of relapsed follicular lymphoma with bone lesions in the left humerus. Within the mid diaphyseal region of the left humerus is a somewhat ill-defined lesion that is dark on T1 and bright on T2 images with probable mild endosteal scalloping. This lesion enhances on postcontrast imaging. There is no adjacent soft tissue involvement.
Intraosseous lesion in the left mid-humeral diaphysis most consistent with the patient's history of lymphoma.
