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

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).
Localization is performed on the body surface by X-ray (a) and puncture is performed under CT guidance (b).

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).
On control CT scan performed during MWA (a) and bone cement was injected into the lesion during the operation (b).

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).
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).

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).
