case_images: Ultrasound images of superficial soft-tissue masses due to lymphatic metastases: A, Female, 2y10m, left neck mass for four days. There were several enlarged lymph nodes in the left neck areas III and IV. The larger one was about 3.2x1.6 cm, oval in shape, with clear boundary, heterogeneous internal echo, patchy hyperechoic foci, and diffuse cortical thickening. B, Blood flow signals in enlarged lymph nodes are more abundant in the periphery than in the center. C, Female, 2y10m, left supraclavicular mass present for more than 4 months. Ultrasound image shows heterogeneous echogenic band with scattered bright echogenic spots and flaky dark area echoes. D, Color Doppler image shows hypoechoic mass with a dot-strip blood flow signal.

case_images: US indicated enlargement of lymph nodes (7/7) and heterogeneous (7/7), hyperechoic foci in the internal mass (5/7) (Figure 1A-D).
case_images: Superficial soft-tissue metastasis of a neuroblastoma. A, Female, 3y2m, right back mass for two years. A hypoechoic mass was observed between the subcutaneous fat layer and innermost intercostal area in the right back. This lump was well circumscribed with internal homogeneous echogenicity without patchy hyperechoic foci. Color Doppler flow imaging showed blood flow signals as dot strips. B, The adrenal area on the right side revealed a hypoechoic mass of 4.3x4.0x2.8 cm. The internal echo is hypoechoic, with hyperechoic foci. C, Female aged two months had numerous lumps in the whole body for one month. The front of the left ear showed a hypoechoic mass with a clear border and a homogeneous echogenic mass. D, The left chest wall indicated a hypoechoic lump with a clear border and heterogeneous internal echo. E, The left retroperitoneum presented a large substantial mass with a clear border and sparsely punctured calcification. The size was 8.0x5.5x4.5 cm. F, The top of the scalp showed an irregular hypoechoic mass with a clear border. It measured 1.0x1.0x0.6 cm. This lump had a heterogenic echo and did not indicate a prominent dark area or calcification. The blood flow signal in color Doppler flow imaging of the hypoechoic group was abundant.

case_images: Postoperative pathology identified the patient as having ganglioneuroblastoma (Figure 2A and B). The patient did not exhibit symptoms such as fever, rash, abdominal pain, or other discomforts (Figure 2C-F).
