Figure 2. 56-year-old male patient with lung adenocarcinoma presented bilateral adrenal metastases after resection of the primary tumor (a) CT-guided microwave ablation was performed on the adrenal metastases in lateral position (b) and prone position (c) respectively. The adrenal metastases showed complete necrosis 6 months after ablation (d).

Figure 3. Recurrence after resection of the adrenal metastases. Four months after radical resection of right-lower lung cancer(pT2aN0M0), the 59-year-old male patient was founded with a right adrenal metastasis (size: 40mm × 29mm). (a) The primary lung tumor. (b) No tumor nodule was found in the right adrenal gland before pulmonary tumor resection. (c, d) The right adrenal metastasis. According to suggestion of the MDT, the patient received the right adrenal tumor resection (e). However, right adrenal metastasis (size: 29mm × 22mm) recurred 3 months after adrenal resection (f).
