Case Report

Failed Switching off in the MIBI-Parathyroid Scintigraphy in a Dialyzed Patient with Secondary Hyperparathyroidism Responsive to Cinacalcet Therapy

Table 2

(a) Scintigraphic and echographic features at the start before calcimimetic administration

Basal study

-MIBI scintigraphy:2 parathyroid glands

scintigraphic features(1) Focal area of increased radiotracer uptake was present posteriorly to the lower pole of the right thyroid lobe
(2) Another smaller area of increased radiotracer uptake was present inferiorly to the lower pole of the left thyroid lobe

CD ultrasound:2 parathyroid glands

Echographic features(1) Nonhomogeneous hypoechoic capsulated area with a vascular pole was present posteriorly to the lower pole of the right thyroid lobe. The major three axes of the parathyroid glands were  mm
(2) Non homogeneous hypoechoic capsulated area with a vascular pole was present inferiorly to the lower pole of the left thyroid lobe. The major three axes of the parathyroid gland were  mm

(b) Scintigraphic and echographic features after one year of calcimimetic administration

After 1 year of cinacalcet therapy

-MIBI scintigraphy 2 parathyroid glands

Scintigraphic featuresThe focal areas of increased radiotracer uptake were unmodified respect to basal control.

CD ultrasound 2 parathyroid glands

Echographic features(1) Echographic structure of the lesion present posteriorly to the lower right pole of the thyroid lobe was unmodified. The major three axes of the parathyroid gland were  mm
(2) Echographic lesion inferiorly to the lower pole of the left thyroid lobe was unmodified respect to basal control
