case_images: Imaging examination. (A-C) adenoma, cervical bronchogenic cyst, and tracheal diverticulum in CT. (D) a hypoechoic nodule in ultrasound. (E) 99mTc-sestamibi single-photon emission computed tomography: Delayed uptake (120min) in the lower panel suggests a parathyroid source. (F) CT multiplanar reformation (CT-MPR) of the neck.

case_images: Afterwards, 99mTc-sestamibi single-photon emission computed tomography (99mTc-MIBI SPECT) manifested that the delayed uptake of tracer (120min and 180min) was slightly higher in the right inferior thyroid gland ( Figures 1A-E ).
case_images: Intraoperative condition. (A) Intraoperative situation of PA. (B, C) Intraoperative situation of CBCs.

case_images: Some tissues were collected to cover the surface of the recurrent laryngeal nerve to protect the nerve, after which the inferior parathyroid nodule was excised, followed by careful excision of the cystic nodule on the bronchus ( Figure 2 ).
case_images: Postoperative pathology. (A) postoperative pathology of PA(10x). (B) postoperative pathology of PA(80x). (C) postoperative pathology of CBCs(10x). (D) postoperative pathology of CBCs(80x).

case_images: Postoperative pathology displayed that the two masses were parathyroid adenomatous hyperplasia and a bronchogenic cyst (pseudostratified ciliated columnar epithelium is visible,  Figure 3 ).
case_images: Postoperative CT. (A) the location of adenom in postoperative CT. (B) the location of cervical bronchogenic cyst in postoperative CT. (C) tracheal diverticulum in postoperative CT.

case_images: Neck CT indicated no recurrence in parathyroid area and no obvious change in tracheal diverticulum ( Figure 4 ).
