What are the clinical features associated with the nuclear medicine study?
Patient has features of primary hyperparathyroidism (elevated serum calcium levels and history of renal calculi) associated with two nodular parathyroid adenomas.
Static and SPECT images were acquired at 15 min and 3 hours. Delayed CT- SPECT was performed.
Initial images show mild focal uptake in the region of the thyroid left upper and right lower poles. No other abnormal extra-thyroid uptake is detected in the rest of the neck or mediastinum. Delayed images show locally retained uptake corresponding to a soft tissue nodule posterior to the left upper pole and another little nodule posterior to the right lower pole. Mild uptake in sub centimetre left supraclavicular lymph nodes is non-specific. Mild uptake in the left anterior mediastinum is probably within physiological limits.
