Ectopic parathyroid adenoma localised with sestamibi SPECT and image-fused computed tomography.
Confident localisation of ectopic parathyroid adenomas, particularly those outside the neck, can be difficult. Even preoperative radiological imaging may not be helpful, as there are few characteristic findings. We report a case in which hyperfunctioning ectopic parathyroid tissue in the mediastinum was detected with technetium-99m-sestamibi single-photon emission computed tomography and accurately localised non-invasively with image-fused computed tomography. This technique directly modified management.
