Chapter 51 discusses amyloidosis, which is a group of rare diseases resulting from protein deposition. Joint involvement is similar in appearance to rheumatoid arthritis, and bone involvement resembles lytic diseases, such as multiple myeloma. Imaging is often acquired because of the primary medical condition and symptoms. Because the imaging characteristics of amyloidosis are often nonspecific, diagnosis is made using tissue biopsy, however, the most characteristic finding is abnormal tissue that is dark on all pulse sequences on MRI. Ultrasound is sometimes used to evaluate the shoulder and guide diagnostic biopsy of abnormal tissue. Treatment of amyloid varies by the cause of amyloidosis.
