In the context of young-onset multiglandular primary hyperparathyroidism and a microprolactinoma, genetic testing was undertaken and no pathogenic variant was identified in MEN1. Based a clinical diagnosis of MEN1 syndrome, a screening MRI of the abdomen was performed; 2 adrenal lesions were found (on the left measuring 59 × 49 mm [-5HU] and on the right 26 × 21 mm [-17HU]) and multiple pancreatic lesions in the body and tail of the pancreas, with the largest measuring 15 × 13 × 10 mm. The gene discussed is MEN1; the disease is Microprolactinoma.
