Dialysis-related amyloidosis

Abstract

Dialysis-related amyloidosis (DRA) is a well-recognized complication in patients on long-term hemodialysis. It occurs secondary to the deposition of beta(2)-microglobulin, preferentially in the musculoskeletal tissues. Plain radiography demonstrates advanced DRA findings such as bone erosions and cystic lesions, but it is not suitable for the demonstration of earlier changes. Magnetic resonance imaging and ultrasound are sufficient for the detection of amyloid deposition in the periarticular soft tissues and in the evaluation of spinal complications.
