Pulmonary alveolar microlithiasis (PAM) is a rare lung disease characterized by the deposition of calcium in the alveolar spaces and bilateral diffuse micronodular ‘‘sandstorm’’ radiographic pattern. The current report presents the case of a 48-year-old woman with pulmonary alveolar microlithiasis. The patient presented with exertional dyspnea for the past five years. The physical examination was within normal limits and respiratory sounds were normal. The chest x-ray revealed a bilateral diffuse micronodular pattern in the middle and the lower areas of both lungs. On the parenchymal window of thorax computed tomography (CT), bilateral diffuse widespread millimetric calcified nodules that were more prominent in the lower lobes were observed. Whole body bone scintigraphy with technetium-99m revealed bilateral, diffuse, heterogeneous, increased uptake in the pulmonary parenchyma. Regarding the current special radiological findings, further invasive diagnostic examination was not performed, the patient was diagnosed with PAM and continues to be followed-up on without treatment.

Pulmoner alveoler mikrolitiyazis (PAM) alveollerde kalsiyum birikmesi ile karakterize nadir görülen bir akciðer hastalýðýdýr. Her iki akciðerde yaygýn simetrik mikronodüler radyolojik pattern mevcuttur. Bu yazýda 48 yaþýnda PAM tanýsý alan bayan hasta sunulmuþtur. Hasta 5 yýldýr eforla geliþen nefes darlýðý ile baþvurdu. Fizik muayene ve solunum sesleri normaldi. Akciðer grafisinde orta ve alt alanlarda bilateral yaygýn mikronodüler patern saptandý. Bilgisayarlý toraks tomografisinde parankim penceresinde bilateral alt loblarda daha belirgin olmak üzere yaygýn milimetrik kalsifiye nodüller izlenmekteydi. Teknesyum-99m ile yapýlan tüm vücut kemik sintigrafisinde her iki hemitoraksta yumuþak doku alanlarýnýnda heterojen tarzda diffüz artmýþ aktivite tutulumu saptandý. Mevcut radyolojik bulgularýn uyumlu olmasý ile ileri giriþimsel tetkik yapýlmadý, hasta PAM tanýsý ile tedavisiz takibe alýndý.
