case_images: A 38-year-old woman with a giant parathyroid adenoma, localized by a sestamibi scan. Immediate (a) and delayed (2-hour) (b) anterior images of (99mTc)-sestamibi demonstrate a focus of intense sestamibi uptake (arrows). Immediate (c), delayed (2-hour) (d) axial fused SPECT/CT images, and transverse noncontrast CT image (e) localized a circular area with focal uptake posterior to the right thyroid lobe (arrows), which was confirmed histologically to be a giant parathyroid adenoma.

case_images: Dual-phase (99mTc)-sestamibi scintigraphy with single-photon emission computed tomography (SPECT) detected a large parathyroid tumor measuring 38 x 18 x 14 mm (craniocaudal x transverse x anteroposterior) located behind the right thyroid lobe compatible with a giant parathyroid adenoma (Figure 1).
case_images: The ultrasound from the patient with a giant parathyroid adenoma. Transverse grayscale images (a) show a giant parathyroid adenoma with a thick capsule and internal echogenic components (arrow). Transverse color doppler images (b) show minimal detectable internal flow (arrow).
