Pulmonary alveolar microlithiasis (PAM) is a rare lung disease, characterized by progressive formation of intra-alveolar calculi in response to an unknown stimulus. We report an unusual presentation of PAM in a 10 year old girl with clinically significant interstitial lung disease and histological evidence of both PAM and lymphocytic interstitial pneumonitis. A rapid improvement of pulmonary fu...

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...

OBJECTIVE To present the high-resolution computed tomography (HRCT) findings of pulmonary alveolar microlithiasis. METHODS The HRCT scans of 10 adult patients (seven females and three males; mean age, 38.7 years) were retrospectively analyzed. The films were studied independently by two radiologists. RESULTS The most common tomographic findings were ground-glass attenuation and linear subpl...
