case_images: T7. The vertebral body was not destroyed and the cervical spinal cord was not compressed (Figure 1).
case_images: Bone scan showed diffuse increased uptake of the isotope at the level of the right transverse process of T7.

case_images: Bone scan showed diffuse increased uptake of the isotope at the level of the right transverse process of T7, without other abnormalities elsewhere in the skeleton (Figure 2).
case_images: Localization is performed on the body surface by X-ray (a) and puncture is performed under CT guidance (b).

case_images: After accurate marking of the skin and in strictly aseptic conditions, local subcutaneous injection of lidocaine 1% was performed at the defined skin entry point and an 11-gauge 15 cm co-axial needle (Dragon Crown Medical Co., LTD, China) was introduced step by step under CT-fluoroscopy (Figure 3a and b).
case_images: On control CT scan performed during MWA (a) and bone cement was injected into the lesion during the operation (b).

case_images: T7 (adjusted during CT guidance), a 16G-gauge 20 cm MWA probe (ECO-100AL6, Nanjing Yigao Medical Technology Co., LTD, China) was advanced into the osseous lesions of T7's right transverse process. Then connect the ablation needle to the ablation instrument (ECO-100A1, Nanjing Yigao Medical Technology Co., LTD, China), adjust the power to 70 W, and ablate twice for 2 min each time (Figure 4a). The distribution of the bone cement is observed until it has diffused to the edge of the lesion (Figure 4b).
case_images: Postoperative CT showed intact cement filling and no leakage in the spinal canal (a) and follow-up after 6 months showed no displacement of the bone cement and no new bone destruction (b).

case_images: CT showed that the cement was well filled and no leaks at the right transverse process of T7 (Figure 5a). At the 6-month follow-up, the patient's chest and back pain was relieved, and a repeat CT revealed no leakage of bone cement and no new destruction of bone (Figure 5b).
