57-year-old female with history of right proximal humerus lesion. Redemonstrated is a heterogeneous lesion within the right proximal humeral metaphysis extending into both the epiphysis and diaphysis. This lesion measures 6.6 cm in maximal sagittal dimensions, previously 6.6 cm (image 18 series 1001). This lesion demonstrates decreased T1 and increased T2 signal with mild irregular enhancement. There are scattered foci of signal void corresponding to calcifications appreciated on plain film. There is no evidence of cortical breakthrough or extraosseous extension. Overall this lesion appears similar to the prior exam.The rotator cuff is grossly intact without evidence of tear. There is a trace amount of fluid within the subacromial bursa as well as mild AC joint osteoarthritis. The anterior and posterior glenoid labrum are grossly intact.
1.Stable right humeral lesion as above likely corresponding to a benign enchondroma.2.Mild AC joint osteoarthritis.
