We report a case of insufficiency fracture in the left hip joint, in which giant tumoral calcinosis occurred during hemodialysis.
The patient was a 36-year-old male on chronic maintanance hemodialysis for 11 years. He experienced left thigh pain upon awaking. Roentgenograms showed a calcified mass in the bilateral hip joint and right shoulder joint. Laboratory tests including intact parathyroid hormone (i-PTH) level were normal, except for increases in serum calcium and phosphorus.
MRI showed that T1 low intensity and T2 high intensity areas around the hip joint subcutaneous and intramuscle.
We performed osteosynthesis with ender nailing, and biopsy of a part of the fracture, and calcinosis in the left hip joint. Microscopic examination revealed calcareous deposits limited by bands of fibrous connective tissue and giant cell. Eel calcitomin puls therapy was given after every hemodialysis. Three months later, after right shoulder calcinosis was decreased on X-ray.
