Background: Parathyroid lipoadenomas are a rare parathyroid phenomenon and an unusual cause of primary hyperparathyroidism. The histological composition of these neoplasms makes them a diagnostic challenge, as their high adipose content leads to difficulty localising them on imaging, and can lead pathologists towards a wrong diagnosis. There are less than 100 cases in the literature since they were first described in 1958, and to our knowledge this is the largest parathyroid lipoadenoma to be reported.

Methods: A minimally-invasive parathyroidectomy with intra-operative parathyroid hormone monitoring was performed in the case of a male with a large neck mass and symptomatic primary hyperparathyroidism.

Results: A giant parathyroid lipoadenoma was excised, with an appropriate decrease in intra-operative parathyroid hormone level observed. The patient has been cured of his primary hyperparathyroidism, with no issues following his discharge from our institution.

Conclusions: We highlight the importance of having the parathyroid lipoadenoma as a differential diagnosis for patients who develop primary hyperparathyroidism.
