Potential benefits of intraoperative parathyroid autofluorescence imaging in a patient with multiple endocrine neoplasia type 1 and hyperparathyroidism - A case report.

INTRODUCTION AND IMPORTANCE

Primary hyperparathyroidism (PHPT) is a frequent complication to multiple endocrine neoplasia type 1 (MEN1), presenting challenges due to increased risk of multi-gland disease and recurrence post parathyroidectomy (PTX). This case report examines the management of PHPT in a MEN1 patient, emphasizing possible benefits from intraoperative parathyroid autofluorescence imaging (AF).

CASE PRESENTATION

A 21-year-old woman with MEN1 presented with mild hyperparathyroidism symptoms in 2014. Initial unilateral PTX in 2015 normalized plasma parathyroid hormone (PTH) and ionized calcium (Ca) but was followed by biochemical recurrence in 2018. In 2022 a subtotal PTX was performed using AF to reduce the risk of permanent hypoparathyroidism. This technique distinguished pathological from non-pathological parathyroid tissue. Most of two glands were removed, leaving a small rim of non-pathologic tissue, achieving long-term normalization of plasma PTH and Ca. Despite prior pregnancy complications suspectedly related to hypercalcemia, she gave birth to a healthy child after the second PTX, who tested negative for MEN1.

CLINICAL DISCUSSION

This case highlights the complexity of managing MEN1-associated PHPT, demonstrating the importance of advanced surgical techniques like AF to minimize complications and enhance outcomes. Surgical and medical management of MEN1 is crucial given the high recurrence-rate. According to the literature, hypercalcemia in patients with PHPT may affect pregnancy outcomes.

CONCLUSION

This case-report emphasize the need for a tailored approach in MEN1-related PHPT, combining innovative surgical methods to optimize outcomes. Further research on the impact of MEN1 on pregnancy outcomes and the long-term efficacy of AF are essential for improving management strategies.
