Case Reports
[Alveolar microlithiasis with severe interstitial fibrosis leading to lung transplantation].
Pulmonary alveolar microlithiasis is a rare disease, characterized by extensive phosphocalcic concretions within the alveolar spaces. Pulmonary alveolar microlithiasis is usually asymptomatic and is incidentally found because radiologic findings are characteristic. In about half of the cases, it is an autosomal recessive disorder due to mutations in the SLC34A2 gene. ⋯ She underwent a lung transplantation when she was 49. Pathological examination confirmed the diagnosis of diffuse pulmonary alveolar microlithiasis with interstitial fibrosis. The patient died 3 months after surgery in an infectious context.
