case_images: Electrocardiogram (ECG) findings on admission (A) and on hospital day 2 (B). (A) An ECG performed on admission shows sinus rhythm with marked QT prolongation (QTc = 0.524 s).. (B) An ECG performed on hospital day 2 shows sinus rhythm with a shortened QT interval (QTc = 0.465 s).. QTc: corrected QT interval

case_images: Her ECG revealed QT prolongation (QTc = 0.524 s) (Figure 1A). Her serum Ca level increased to 1.63 mmol/L on day 2, and the QT interval on ECG (QTc) decreased to 0.465 s (Figure 1B).
case_images: Head computed tomography performed on admission, showing an absence of calcification of the basal ganglia

case_images: Head computed tomography shows no calcification of the basal ganglia (Figure 2).
case_images: Genetic testing of the patient. (A) Chromosome analysis showing a normal G-banded chromosome (46,XX).. (B) Fluorescence in situ hybridization showing a lack of deletion or duplication of the domain of 22q11.2 responsible for 22q11.2 deletion syndrome (red with white arrows).

case_images: Additional diagnostic tests to exclude DiGeorge syndrome type 1 as the etiology of the patient's hypoparathyroidism showed normal G-banded chromosome analysis findings (46,XX) and no 22q11.2 deletion on fluorescence in situ hybridization screening (Figures 3A, 3B).
case_images: Ultrasound image of the thyroid of the patient. (A) Right lobe of the thyroid. (B) Left lobe of the thyroid.. The parathyroid glands were not observed.
