Stridor in older children can be due to diverse aetiology that includes infections, anaphylaxis and rarely systemic conditions leading to hypocalcaemia. We report the case of a previously asymptomatic 11-year-old girl who presented to the casualty with stridor due to hypocalcaemia. The aetiological investigations for hypocalcaemia uncovered previously undetected chronic renal failure, possibly due to a rare autosomal recessive condition called nephronophthisis. We report this case to highlight the importance of widening the diagnostic focus for children presenting with stridor, especially when they fall outside the usual age group for infections like croup, or when the history is atypical.
大龄儿童喘鸣可能由多种病因引起，包括感染、过敏反应，以及罕见的导致低钙血症的全身性疾病。我们报告一例先前无症状的11岁女孩，因低钙血症出现喘鸣而前来急诊。低钙血症的病因学检查发现了先前未被检测出的慢性肾衰竭，可能是由于一种名为肾单位肾痨的罕见常染色体隐性疾病所致。我们报告此病例以强调对于出现喘鸣的儿童扩大诊断范围的重要性，尤其是当他们不属于如哮吼等感染的常见年龄组，或病史不典型时。
