Extensive pulmonary alveolar microlithiasis
نویسندگان
چکیده
Pulmonary alveolar microlithiasis is a rare pulmonary disorder that is caused by abnormal sodium-dependent phosphate co-transporter from the mutation of SLC34A2 gene, leading to accumulation of microliths in the alveoli. We report the extensive pulmonary alveolar microlithiasis in an elderly woman who presented with progressive dyspnea for 2 months. Chest radiograph revealed diffuse pulmonary calcification. Tissue histopathology from open lung biopsy demonstrated widespread intra-alveolar laminated calcium deposits compatible with pulmonary alveolar microlithiasis.

s:696:"Pulmonary alveolar microlithiasis (PAM) is classified as an elective dysmetabolic thesaurotic pneumoalveolitis and characterized by the presence within the alveoli of the lungs of myriad of tiny calculi. The classic presentation of the chest radiography is unmistakable with multiple small "sand-like" opacities diffusely involving both lung fields. We present a case of male infertility fo...

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...
متن کاملA Case Report of Pulmonary Alveolar Microlithiasis
Pulmonary alveolar microlithiasis is a rare autosomal recessive disease characterized by the formation of calcium phosphate deposition in the alveoli. Although the disease most often occurs in children, most patients with the disease are diagnosed in adulthood due to the slow progression of the disease inside the lungs. In childhood, it often causes no symptoms, and changes in the lung parenchy...

This report describes a case of pulmonary alveolar microlithiasis that was diagnosed in an 8.5-year-old girl by high-resolution computed tomography (CT) and open lung biopsy. Presence of symptoms (productive cough, fever), their periodic occurrence (lasting up to 1 week), and comparatively long asymptomatic periods should be emphasized. Despite extensive X-ray abnormalities, tests of pulmonary ...
