Abstract
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 for hypoposia and severe oligoasthenospermia in a young patient with recurrent haematuria and small calcifications in the seminal vesicles similar to pulmonary microliths. PAM was diagnosed on routine chest radiography, com- puter tomography (CT), transbronchial biopsy and bronchoalveolar lavage (BAL).
