Demographic and clinical characteristics and preoperative parathyroid ultrasound (US) and technetium-99m sestamibi (<jats:sup>99m<\/jats:sup>Tc-MIBI) scintigraphy results were collected.

The median age was 30 years. Sixteen (16\/19, 84.2%) patients had single-gland disease and three (15.8%) had two lesions. Three patients were confirmed as multiple endocrine neoplasia type 1. The median size of all lesions was 1.8\u00a0cm (0.6\u20137.5\u00a0cm). All patients had undergone US examination, and eight patients had <jats:sup>99m<\/jats:sup>Tc-MIBI scintigraphy. A total of 21 lesions were found on US. The diagnostic sensitivity of the US was 95.45% per lesion and 100% per patient. One lesion, with a maximum diameter of 0.6\u00a0cm, was missed preoperatively by either US or <jats:sup>99m<\/jats:sup>Tc-MIBI scintigraphy. Nine patients had surgery in the second trimester and 88.89% of them had a full-term pregnancy after surgery.
