case_images: A 58-year-old man treated GIST metastases in the chest wall with MWA. (A-C) In January 2022, preoperative MRI showed a mass of 5.6x3.2 cm in the rib, and CEUS showed heterogeneous enhancement. (D-F) In February 2022, the tumor size was similar to before, CEUS showed partial enhanced area. (G-I) In April 2022, the tumor size was 5.3x2.4cm, and CEUS showed enhanced area. (J-L) 17 months after the second ablation, the tumor size was 4.7x1.6 cm, and CEUS showed no enhancement. MRI, magnetic resonance imaging; CEUS, contrast-enhanced ultrasound; the white arrow, lesion in the rib.

case_images: Magnetic resonance imaging (MRI) revealed a 5.6x3.2 cm mass in the rib, together with several solid nodules in the soft tissue ( Figures 2A, B ). Contrast-enhanced ultrasound (CEUS) showed a hypoechoic mass in the rib and several hypoechoic nodules in the chest wall, with heterogeneous enhancement in the arterial and venous phases ( Figure 2C ). In February 2022, MRI showed a comparable tumor size ( Figures 2D, E ). CEUS revealed both necrotic tissue and remaining enhanced tissue in the ablation sites ( Figure 2F ). In April 2022, a follow-up MRI scan conducted three months following the first ablation revealed that the rib lesion had decreased in size, now measuring 5.3x2.4 cm ( Figures 2G, H ). CEUS showed some degree of enhancement in the area ( Figure 2I ). The MRI and CEUS revealed that the ablation area measured 4.7x1.6 cm, which was significantly smaller ( Figures 2J-L ).
