What are the most common risk factors for this condition?
End stage renal disease (ESRD) and secondary hyperparathyroidism may lead to large amounts of periarticular heterotopic calcification. The term "tumoral calcinosis", however, is reserved for the idiopathic form.
There is a large amount of "fluffy" heterotopic calcification around the right hip joint. The underlying proximal right femur is not well seen, but appears intact.
A rim-calcified fibroid is also noted.
