case_images: Ultrasound revealing a hypoechoic area with 1.1*0.3 cm on the dorsal side of the left inferior pole of thyroid (A). Parathyroid adenoma was confirmed by core needle biopsy, which was composed of chief, transitional, oncocytic, and water clear cells (B). Normal saline solution was injected into the region between the parathyroid adenoma and vital structures of the neck to protect recurrent laryngeal nerve, esophagus and trachea adjacent to the parathyroid adenoma (C). Antenna was located in the parathyroid adenoma (D). Ablation was finished until the entire nodule was covered with hyperechoic microbubbles (E).

case_images: The ultrasound revealed a hypoechoic area with 1.1*0.3 cm on the dorsal side of the left inferior pole of thyroid (Figure 1A), which is a common location for lower polar parathyroid. Finally, it was confirmed to be parathyroid adenoma by routine sectioning and staining with hematoxylin and eosin (Figure 1B). Then, normal saline solution was injected into the region between the parathyroid adenoma and vital structures of the neck to protect recurrent laryngeal nerve, esophagus and trachea adjacent to the parathyroid adenoma (Figure 1C). After determining that the tip of the needle was located in parathyroid adenoma (Figure 1D), ablation was started under closely ultrasound monitoring. Moving the needle tip to ablate the whole parathyroid adenoma until the entire nodule was covered with hyperechoic microbubbles (Figure 1E).
