📸 Key X-ray findings • Diffuse, bilateral micronodules (1–3 mm) throughout both lung fields • Uniform distribution from apices to bases → classic miliary pattern • Well-defined tiny nodules giving a “sand-like” appearance • No zonal predominance (unlike TB which may be upper-zone dominant) • Normal cardiac size (helps differentiate from pulmonary oedema) • May coexist with normal or minimally abnormal CXR early on ⚠️ Important differentials • Miliary tuberculosis • Sarcoidosis • Pneumoconiosis
