case_images: The electocardiogram showed normal sinus rhythm with complete right bundle branch block pattern. The chest P-A showed confluent increased density in right upper lobe, right middle lobe and both lower lobes with blunting of left costophrenic angle, and also Derlie's B line in both lower lung fields (Fig. 1).
case_images: The chest roentgenogram on the 5th hospital day shows aggravated airspace consolidation in both lung fields.

case_images: The follow-up chest X-ray, five days after antibiotics, revealed aggravated and migrating confluent alveolar consolidations (Fig. 2).
case_images: The High-resolution CT of the lung shows ground-grass opacities, airspace consolidation and interlobular septal thickening bilaterally.

case_images: The high resolution computed tomography revealed patchy or lobar distributed increased opacities with air-bronchograms on both upper lobes, right middle lobe and both lower lobes, thickening of interlobular septums and also noted bilateral minimal pleral effusions (Fig. 3).
case_images: The microphotograph shows mild interstitial thickening (A) and intra-alveolar foamy macrophages (B) (H-E, A: x100, B: x400).

case_images: Most air spaces were filled with a variable number of foamy alveolar macrophages (Fig. 4).
case_images: The electron microscopy demonstrates many osmiophilic lamellated bodies in the cytoplasm of foamy alveolar macrophages (uranyl acetate and lead citrate, x7,000).

case_images: Ultra-structural findings demonstrated multiple electron dense lamellar bodies in the cytoplasm of foam cells (Fig. 5).
case_images: Follow-up chest X-ray at 15th day after withdrawal of amiodarone shows much improved infiltrations compared with those of previous films.

case_images: Five days after withdrawal of amiodarone, clinical findings and X-ray findings were improved (Fig. 6).
