Background:

Primary hyperparathyroidism (PHPT) diagnosis often relies on imaging to localize parathyroid adenomas (PTA).
Ectopic PTAs can present diagnostic challenges, particularly in unusual locations like the retropharyngeal space.
Standard imaging modalities may have limitations in detecting subtle or ectopic parathyroid pathology.

Keywords:

Ectopic Tc-99m-sestamibi scan parathyroid adenoma retropharyngeal
