TOPIC: Diffuse Lung Disease TYPE: Fellow Case Reports INTRODUCTION: Pulmonary alveolar microlithiasis (PAM) is an extremely rare lung disease characterized by the development of calcium phosphate deposits (microliths) within spaces. Genetic mutations in SLC34A2 gene (solute carrier family 34 member 2 gene), which encodes for a sodium-phosphate co-transporter, have been described as cause diseas...

Pulmonary alveolar microlithiasis is an uncommon infiltrative pulmonary disease characterized by deposition of microliths in the alveoli. We present the case of a young adult with complaints of shortness of breath on exertion. Chest radiograph showed innumerable small, dense nodules, diffusely involving both the lungs - predominantly in the lower zones. High-resolution CT scan illustrated wides...

Radiol Bras. 2015 Set/Out;48(5):IX–X In previous issue of Radiologia Brasileira, readers can find a very interesting article published by Francisco et al. about pulmonary alveolar microlithiasis (PAM). The authors describe the highresolution computed tomography (HRCT) findings in chest exams of 13 patients with PAM, independently evaluated by two observers. According to the authors, diagnoses o...

Pulmonary alveolar microlithiasis (PAM) is a rare disease of unknown origin in which calcific concretions collect in alveolar spaces. No known cause for the disease had been identified and there appears to be no systemic disorder of calcium metabolism. Plain chest X-ray shows a white lung consisting of fine sandlike micro calcification diffusely scattered throughout both lungs with high density...
