Images from a 68-year-old male with chest pain for a week. (a) B-mode sonogram showed a heterogeneous lesion (M) with air-bronchogram in inferior lobe of right lung. (b) CEUS showed a regular necrosis () in the center of lesion. (c) US-guided transthoracic biopsy was performed after CEUS and biopsy was targeted in the enhanced area () to avoid necrotic area. (d) Pathological result from biopsy demonstrated a benign pulmonary inflammatory pseudotumor (hematoxylin-eosin, original magnification ×200).
