Multi-modality parathyroid imaging: A shifting paradigm

Figure 9 Ectopic parathyroid adenoma in the anterior mediastinum. A: Computed tomography in a 45-year-old male patient showed a well-defined ovoid lesion in the prevascular space just posterior to the sternal notch and anterior to the inferior thyroid vessels appearing hypodense on the non-contrast phase; B: Showing intense enhancement on the arterial phase; C: washout in the venous phase; D: Coronal maximum intensity projection image demonstrates the inferior thyroid artery supplying the lesion (feeding vessel - black arrows); E: Fluoro-choline positron emission tomography shows a small tracer avid lesion in ectopic location which correlates with the computed tomography images.
