Fig. 2From: Recurrence hyperparathyroidism caused by synchronous parathyroid carcinoma and parathyromatosis in a patient with long-term hemodialysisThe 99mTc-MIBI SPECT/CT scan shows focused tracer accumulation with a low-density nodule located inferior to the left thyroid gland (red arrows: A SPECT, B axial image, C coronal SPECT/CT fusion image, D coronal SPECT image). Contrast-enhanced CT scan reveals arterial-phase (D) and delayed-phase (E) axial images of a moderately enhanced parathyroid nodule (red arrows) located inferior to the left thyroid gland.
