Pulmonary alveolar microlithiasis (PAM) is a rare disease with unknown etiology and pathogenesis. It is characterized by diffuse, innumerable, and minute calculi, called microlithiasis in the alveoli. More than half of reported cases are asymptomatic at the time of diagnosis. We describe the first case of PAM in Korea. A 19-yr-old man without respiratory symptoms presented with interstitial thi...

Pulmonary alveolar microlithiasis is a rare infiltrative pulmonary disease characterized by deposition of microliths in the alveoli. In this case report, we present a case of a 5 year-old girl with complaints of common cold and loss of appetite. Chest radiograph showed innumerable small, dense nodules, diffusely involving both lungs. High-resolution CT scan illustrated widespread micro-nodular ...

Pulmonary alveolar microlithiasis (PAM) is a rare idiopathic disease of unknown etiology and pathogenesis. PAM is characterized histopathologically by extensive intra-alveolar calcium and phosphate deposition throughout both lung parenchymas. None-invasive diagnosis of pulmonary calcification and ossification requires various imaging techniques, including chest radiography and computed tomograp...

Pulmonary alveolar microlithiasis (PAM) is a rare disease of unknown etiology characterized by accumulation of calcific concretions in the alveolar spaces. The paper reports a case of PAM in a 56-year-old male. The patient had persistent dry cough, and gradually progressive dyspnea on exertion. The diagnosis was established on the basis of roentgenography and confirmed by the sputum and transbr...

Pulmonary alveolar microlithiasis (PAM) is a rare disease of unknown aetiology. It is characterized by the presence of calcific concretions (calcospherites) inside the alveoli. We present a case of a 22 year old sickle cell anaemia patient with an incidental finding of PAM. This report is to highlight the fact that though rare, PAM is not entirely unheard of in this environment and should be ke...

Haemogram parameters and serum biochemistry, including calcium, phosphorous and alkaline phosphatase levels were within normal limits. The chest radiograph (Figure 1) showed bilateral middlezone and lower-zone dense reticulonodular opacities. High resolution computed tomography (HRCT) of the chest (Figures 2 and 3) showed bilateral intra-lobular interstitial and septal thickening with a perivas...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2015-212804 DESCRIPTION A 47-year-old asymptomatic man with no significant family history was referred to our faculty because of an abnormal chest X-ray (CXR). The CXR, similar to his CXR 10 years previously, showed bilaterally increased interstitial markings suggestiv...
