| Abstract: | A 6-year-old girl presented with respiratory distress. Chest radiographs exhibited calcifications in the mediastinum. Further imaging revealed extensive cardiac calcifications on computed tomography of the chest. The laboratory parameters were consistent with findings of secondary hyperparathyroidism. Detailed review of her dietary history revealed a prolonged history of dietary deficiency of calcium and vitamin D. Treatment consisted of adequate daily replacement of calcium and ergocalciferol. On follow-up, her parathyroid hormone level was significantly reduced and substantially reduced cardiac calcifications were seen on echocardiogram. Pediatric cardiologists must be aware of this potentially fatal but treatable disease in children with cardiac calcifications unexplained by other causes. |
