Metastatic pulmonary calcification is a metabolic lung disease that occurs due to a prolonged hypercalcemic state where calcium salts precipitate into numerous foci or nodules of fluffy calcifications in the lung apices, usually bilaterally. Calcifications can also occur in other organs such as in the stomach and the kidneys. It is often underdiagnosed and is usually associated with end stage renal failure and resultant secondary hyperparathyroidism. Nevertheless, it is rarely reported in the postcardiac surgery status and cardiac transplant patients. We present a case of a 15-year-old male patient with a recent history of cardiac transplant due to a complex congenital heart disease where findings of extensive metastatic pulmonary calcifications were seen a routine follow-up chest radiograph. Clinical manifestations of metastatic pulmonary calcifications can range from having no symptoms or mild dyspnea on exertion to fulminant respiratory failure. Therefore, early recognition of imaging features and initiation of proper management is crucial to the patient's outcome.
转移性肺钙化是一种代谢性肺部疾病,由于长期高钙血症状态而发生,钙盐沉淀在肺尖部形成许多絮状钙化灶或结节,通常双侧受累。钙化也可发生在其他器官,如胃和肾脏。它常常被漏诊,通常与终末期肾衰竭及由此导致的继发性甲状旁腺功能亢进有关。然而,在心脏手术后状态和心脏移植患者中很少有报道。我们报告一例15岁男性患者,因复杂先天性心脏病近期接受了心脏移植,在常规随访胸部X线片上发现广泛的转移性肺钙化。转移性肺钙化的临床表现可从无症状或运动时轻度呼吸困难到暴发性呼吸衰竭。因此,早期识别影像学特征并开始适当的治疗对患者的预后至关重要。
