case_images: Radiological images before ultransonography (US)-guided lung biopsy. (A) Signs of infiltration present in the left lower lung field. (B,C) Plane computed tomography (CT) at the previous hospital revealing a round soft tissue mass and a small amount of pleural effusion in the left lung. (D) Chest X-ray revealed a left lung nodule measuring 2 cm in diameter. (E,F) Contrast-enhanced CT of the chest showing a rim-enhancing lesion in the left lower lobe lung.

case_images: Chest radiography demonstrated left lobe pneumonia (Figure 1A), while blood examination revealed a white blood cell count (WBC) of 10.4x 109/L with 58.5% neutrophils and C-reactive protein levels < 0.50 mg/L. A subsequent plane computed tomography (CT) scan of the chest disclosed a round soft tissue mass and a small amount of pleural effusion in the left lung (Figures 1B,C). On hospital day 5, a chest X-ray revealed a left lung nodule measuring 2 cm in diameter (Figure 1D), which was similar to the previous. This was confirmed by a contrast-enhanced CT scan revealing a rim-enhancing lesion in the left lower lobe lung (Figures 1E,F).
case_images: Radiological images after US-guided lung biopsy and appropriate treatment. (A) A repeated chest X-ray demonstrating partial resolution of the mass on hospital day 8. (B) Reddish-brown purulent pleural fluid. (C,D) A repeat chest scan confirming obvious resolution of the lung nodule on hospital day 20. (E,F) Follow-up CT after 3 months showing nodule resolution without any residual lesion.

case_images: A repeated chest X-ray showed partial resolution of the mass (Figure 2A) on hospital day 8, but an ultrasound revealed pleural effusion on hospital day 11. A thoracentesis was performed evacuating 190 ml of reddish-brown purulent pleural fluid (Figure 2B). A repeat chest scan confirmed the obvious resolution of the lung nodule and disappearance of the pleural effusion on hospital day 20 (Figures 2C,D). Follow-up CT after 3 months showed nodule resolution without any residual lesion (Figures 2E,F).
