case_images: Imaging examination upon admission and reexamination of imaging examination. (A) Abdominal ultrasound: Irregular hypoechoic area in the S4 segment of the left lobe of the liver (Red arrow, 21 mm x 10 mm); A low echo mass (Yellow arrow, 5 mm x 5 mm) can be seen next to it, there was no obvious blood flow signal. (B) Abdominal CT plain scan and enhancement: liver S4 segment abscess (Red arrow, 29 mm x 36 mm x 33 mm), circular low density non enhanced liquid density shadow with a size of approximately 12 mm x 8 mm can be seen inside it. (C,D) Recheck liver ultrasound on the 3rd day and 4th day of admission: no significant change in abscess size (Red arrow, 19 mm x 14 mm, 6 mm x 5 mm) and no new abscess. (E) Abdominal MRI plain scan and enhancement on the 21st day of admission: significant absorption of liver S4 segment abscess lesions, with local small pus cavities remaining (Red arrow, 15 mm x 11 mm x 19 mm).

case_images: They seems connected with each orther (Figure 1A). On the second day of admission, abdominal CT plain scan and enhancement: considering liver S4 segment abscess: range 29 mm x 36 mm x 33 mm, circular low density non enhanced liquid density shadow with a size of approximately 12 mm x 8 mm can be seen inside it (Figure 1B). Recheck liver ultrasound on the 3rd day (Figure 1C) and 4th day (Figure 1D) of admission, respectively. On the 21st day of admission, abdominal MRI plain scan and enhancement (Figure 1E) showed significant absorption of liver S4 segment abscess lesions (15 mm x 11 mm x 19 mm), with local small pus cavities remaining.
case_images: Post-discharge follow-up imaging results. (A) Abdominal ultrasound (one month after discharge): liver abscess had shrunk (Red arrow, 3.5 mm x 2.8 mm). (B) Abdominal ultrasound (three month after discharge): liver abscess had absorbed. (C) Abdominal CT scan (eight month after discharge): no liver parenchymal lesions.

case_images: One month after discharge, the abdominal ultrasound examination showed that the liver abscess had shrunk (3.5 mm x 2.8 mm) compared to before (Figure 2A). After 3 months of discharge, the abdominal ultrasound examination showed that the liver abscess had absorbed (Figure 2B), and the growth and development of the patient were good. After 8 months of discharge, abdominal CT scan showed no liver parenchymal lesions (Figure 2C).

case_images: Imaging examination upon admission. (A) Lung ultrasound: elliptical consolidation lesions in the right axillary area (Red arrow, 32.3 mm3 x 20.2 mm3 x 18.1 mm3). (B) Lung ultrasound: elliptical consolidation lesions in the left lower lung (Red arrow, 22.2 mm3 x 16.4 mm3 x 15.8 mm3). (C) Chest x-ray examination: indicating right pneumonia. (D) An elliptical soft tissue mass shadow in the posterior segment of the right upper lobe (Red arrow, 31 mm3 x 22 mm3 x 20 mm3), with a large necrotic area in the center. (E) Multiple nodules and lumpy shadows in the lower lobe of the left lung (Red arrow, up to approximately 25 mm3 x 22 mm3 x 15 mm3).

case_images: On the second day of admission, lung ultrasound examination revealed elliptical consolidation lesions in the right axillary area and the dorsal side of the left lower lung (the size of the lesion in the right lung is about 32.3 mm3 x 20.2 mm3 x 18.1 mm3, left lung lesion size approximately 22.2 mm3 x 16.4 mm3 x 15.8 mm3), considering the possibility of lung abscess (Figures 3A,B). Upon admission, a chest x-ray examination was performed simultaneously, indicating right pneumonia (Figure 3C).
case_images: Post-treatment follow-up imaging results. (A) Chest x-ray showed an improvement in pneumonia compared to before. (B,C) Lung ultrasound: an irregular small consolidation (Red arrow, 25.8 mm3 x 12.2 mm3 x 10.3 mm3) in the posterior axillary area of the right upper lung, a small amount of bronchial inflation sign is visible, and no significant consolidation is detected in the rest of the right lung and left lung. (D,E) Chest CT scan: lumpy shadows in both lungs, with a right lung lesion size of approximately 15 mm3 x 20 mm3 x 28 mm3, with a left lung lesion size of approximately 20 mm3 x 17 mm3 x 10 mm3, smaller than before. (F-I) Lung ultrasound: an irregular small consolidation (Red arrow, 12.2 mm x 8.6 mm) in the posterior axillary area of the right upper lung, with a small amount of bronchial inflation sign visible. No significant consolidation was detected in the remaining areas of the right lung and left lung (J) Chest CT scan: patchy slightly high-density shadows in the upper and lower lobes of the right and left lungs, the lesions in both lungs are significantly absorbed and reduced compared to before, and the cavities disappear.

case_images: After one week of treatment, the chest x-ray showed an improvement in pneumonia compared to before (Figure 4A). Lung ultrasound (Figures 4B,C) shows an irregular small consolidation with a size of approximately 25.8 mm3 x 12.2 mm3 x 10.3 mm3 in the posterior axillary area of the right upper lung, a small amount of bronchial inflation sign is visible, and no significant consolidation is detected in the rest of the right lung and left lung. Chest CT scan shows lumpy shadows in both lungs, with a right lung lesion size of approximately 15 mm3 x 20 mm3 x 28 mm3, smaller than before (Figures 4D,E). No significant consolidation was detected in the remaining areas of the right lung and left lung (Figures 4F-I). The lesions in both lungs are significantly absorbed and reduced compared to before, and the cavities disappear (Figure 4J).
