Localization of Parathyroid Disease in Reoperative Patients with Primary Hyperparathyroidism

Figure 6

Multigland disease on four-dimensional computed tomography (4DCT). A 44-year-old female presents with recurrent hyperparathyroidism after prior right inferior parathyroidectomy. Axial precontrast (a) and postcontrast (b) early arterial phases show a moderately enhancing overly descended right superior parathyroid adenoma (white arrows) and a small hyperenhancing orthotopic left inferior parathyroid adenoma (red arrows). Coronal (c) and sagittal (d) views similarly demonstrate the overly descended right superior parathyroid adenoma (white arrows).
