| Background |
|---|
Secondary hyperparathyroidism is a common complication of end-stage renal disease (ESRD), which occurs as a result of hyperphosphataemia, hypovitaminosis D and hypocalcaemia. Chronic hyperparathyroidism can result in osteitis fibrosis cystica, also known as brown tumours. Spinal cord compression from a brown tumour is a rare emergency and of the eight reported cases in the literature, this represents the first case while undergoing treatment with sevelamer and cinacalcet. Although cinacalcet may have a role in the metabolic control of hyperparathyroidism, caution needs to be taken in delay or avoidance of parathyroidectomy in severe cases, as it may cause delays in necessary therapy.
