case_images: (A) Two rounded nodules in the right lower lobe of the lung, with well-defined borders and a diameter of about 6 mm. (B) Significant enhancement of the nodules in the arterial phase. (C) Coronal image showing the location of the nodules near the heart and diaphragm. (D)
  68Ga- DOTATATE PET-CT did not show significant drug uptake.

case_images: The patient underwent 68Ga- DOTATATE ( Figure 1 ), and 18F-FDG PET-CT. 68Ga- DOTATATE PET-CT did not show significant uptake while 18F-FDG PET-CT showed mild radiotracer uptake (standard uptake value 2.2 g/ml).
case_images: (A) Under CT guidance, the radiofrequency ablation probes (long arrow) were placed for the two lesions, and local nerve block anesthesia (short arrow) was performed using a 21G Chiba needle to the diaphragm. (B) A semi-automatic biopsy was used to obtain the tumor tissue from one of the lesions. (C) A scan was performed after 12 min of ablation with a power of 30 w, showing the formation of a halo sign around the lesion. (D) After removing the needle and probes, the CT scan showed substantial localized changes in the ablation zone. A small amount of bleeding from the puncture needle tract with a small amount of pneumothorax on the right side. (E) A follow-up one week after the operation showed a well-defined solid area in the ablation zone.

case_images: The needle tract was ablated and blocked by injecting a mixture of snake venom hemagglutinin injection (Sounaswe, 1 ml) and an absorbable gelatin sponge (Geiloam, 100 mg) through the needle sheath ( Figure 2 ).
