A 65-year-old woman presented with a four-week history of increased fatigue, intermittent chest pain, dyspnea, and frequent constipation. Biochemistry showed hemoglobin of 95 g/L (baseline 130 g/L) and an estimated glomerular filtration rate of 5 ml/min/1.73m2 (baseline 50 ml/min/1.73m 2 ). Initial chest radiograph revealed multiple unexplained rib fractures, which prompted a further skeletal survey, including a radiograph of the skull (image).
