Abstract

BACKGROUND:

Recurrent primary hyperparathyroidism (PHPT) presents a diagnostic challenge in localizing a hyperfunctioning gland. Although several imaging modalities are available for preoperative localization, 4D-CT is increasingly utilized for its ability to locate both smaller and previously unlocalized lesions. Currently, there is a paucity of data evaluating the utility of 4D-CT in the reoperative setting compared with ultrasound (US) and sestamibi. We aimed to determine the sensitivity of 4D-CT in localizing parathyroid adenomas in recurrent or persistent PHPT.

METHODS:

We performed a retrospective review of prospectively collected data from a tertiary-care hospital, and identified 58 patients who received preoperative 4D-CT with US and/or sestamibi between May 2008 and March 2016. Data regarding the size, shape, and number of parathyroid lesions were collected for each patient.

RESULTS:

A total of 62 lesions were identified intraoperatively among the 58 patients (6 with multigland disease) included in this investigation. 4D-CT missed 13 lesions identified intraoperatively, compared with 32 and 22 lesions missed by US and sestamibi, respectively. Sensitivity for correct lateralization of culprit lesions was 77.4% for 4D-CT, 38.5% for US, and 46% for sestamibi. 4D-CT was superior in lateralizing adenomas (49/62) compared with US (20/52; p < 0.001) and sestamibi (18/47; p < 0.001). The overall cure rate (6-month postoperative calcium < 10.7 mg/dL) was 89.7%. All patients with lesions correctly lateralized by 4D-CT were cured at 6 months.

CONCLUSION:

4D-CT localized parathyroid adenomas with higher sensitivity among patients with recurrent or persistent PHPT compared with sestamibi or US-based imaging.
