Presentation
Renal failure. On peritoneal dialysis.
Patient Data
Tumoral calcinosis inferior to the right shoulder joint. Bilateral calcification of the coracoclavicular ligaments and bone resorption around the acromioclavicular joints.
Tumoral calcification in the right hip joint, right ilium tendon origins and bilateral trochanteric bursae.
Ascites and peritoneal catheter in situ as well as small kidneys in keeping with the background renal disease.
Case Discussion
The dominant imaging feature of renal osteodystrophy in this patient is the widespread soft tissue calcification, with tumoral calcinosis seen in the hands; massive soft tissue calcification inferior to the right shoulder (on CXR), and on the CT - in the right hip joint, right ilium tendon origins and bilateral trochanteric bursae. There is also bilateral calcification of the coracoclavicular ligaments (on CXR). Bone resorption is absent or minimal in the hands, but is evident around the AC joints.
