Summary

Persistent hyperparathyroidism (HPT) after surgery can be challenging. Magnetic resonance imaging (MRI) successfully located an ectopic parathyroid adenoma missed by other imaging methods.

Background:

Persistent hyperparathyroidism (HPT) can occur after parathyroid gland surgery.
Locating persistent or recurrent disease, especially ectopic adenomas, is crucial for successful treatment.

Observation:

A 34-year-old woman had persistent HPT despite prior surgery.
Standard imaging including ultrasound (US), computed tomography (CT), and scintigraphy failed to identify the cause.
Magnetic resonance imaging (MRI) precisely located an ectopic parathyroid adenoma in the carotid sheath.

Findings:

MRI is highly effective in identifying ectopic parathyroid adenomas causing recurrent HPT.
Multimodality imaging plays a role, but MRI offers superior soft-tissue contrast for challenging cases.

Implications:

Accurate localization of ectopic parathyroid adenomas is essential for surgical planning and successful HPT management.
This case highlights the utility of MRI in diagnosing persistent HPT when other imaging modalities are inconclusive.
