Imaging findings
Diffuse, widespread calcified nodules throughout both lungs, without associated fibrosis or lymphadenopathy.
Key takeaways
Pulmonary alveolar microlithiasis is a rare condition characterized by widespread alveolar calcifications. While classic textbook cases often show more severe, diffuse calcifications, this case represents a milder presentation, independently confirmed by two bronchoscopies. It's a progressive disease that may eventually require transplant evaluation.
