Massive, painful tumoral calcinosis in a long-term hemodialysis patient

Treatment of a soft tissue calcification in a patient receiving peritoneal dialysis

Chronic Kidney Disease patients suffer from Mineral and Bone Disorder (CKD-MBD) leading to increased vascular and soft-tissue calcification. The prevalence of soft tissue calcification in dialysis patients is not well described, and most cases describe such calcifications in hemodialysis patients. We describe a case of a massive soft tissue calcification in the right gluteal region in a peritoneal dialysis patient. The patient had severe pain and were disabled. The treatment was converted to an intensive hemodialysis regimen with a minimal calcium load and high dose of cinacalcet. During the treatment, the calcification diminished rapidly from a diameter of 26.6 to 2.9 cm, and the patient symptoms were relieved, leaving the patient with no pain or restriction in mobilization.

Musculoskeletal manifestations of endocrine disorders

Endocrine disorders can lead to disturbances in numerous systems within the body, including the musculoskeletal system. Radiological evaluation of these conditions can demonstrate typical appearances of the bones and soft tissues. Knowledge of these patterns can allow the radiologist to suggest a diagnosis that may not be clinically apparent. This review will highlight the typical musculoskeletal findings of acromegaly, hypercortisolism, hyperthyroidism, hypothyroidism, hyperparathyroidism, pseudo- and pseudopseudohypoparathyroidism, and diabetes mellitus. The radiological manifestations of each of these endocrine disorders, along with a brief discussion of the pathophysiology and clinical implications, will be discussed.

Cervical tumoral calcinosis with secondary hyperparathyroidism in a chronic hemodialysis patient

Tumoral calcinosis is an uncommon and severe complication of chronic renal failure. It is generally associated with the presence of a high-serum calcium-and-phosphorus product. We report here a case of a patient on maintenance hemodialysis who presented with progressively increasing, solitary, tumor-like swelling over the nape of the neck. A 50-year-old female on thrice weekly maintenance hemodialysis for the last 3 years presented with a small swelling over the nape of the neck that had been progressively increasing over the last 1 year to cricket ball size. The patient was investigated and diagnosed as having tumoral calcinosis. The metastatic calcification occurring in the patient was most likely related to high calcium × phosphate product with coexistent secondary hyperparathyroidism possibly aggravated by vitamin D therapy. The patient was treated with withdrawal of vitamin D therapy, strict control of serum phosphate levels with noncalcemic phosphate binders, and subtotal parathyroidectomy. The neck swelling started decreasing in size after 2 months of parathyroidectomy and there was marked clinical improvement with drop in serum parathormone levels, over a period of 6 months. After 2 years of parathyroidectomy, the neck swelling again started increasing in size with increase in serum parathormone levels. The patient was treated with cinacalcet and the neck swelling gradually decreased in size along with control of serum parathormone and phosphate levels.
