Summary

The objective of the study is to report a case of acute pancreatitis secondary to hypercalcemia induced by primary hyperparathyroidism in a pregnant woman at the end of the first trimester. The case included a 32-year-old woman who was diagnosed with acute pancreatitis and severe hypercalcemia refractory to many regimens of medical therapy in the first trimester of pregnancy. She was successfully treated with parathyroidectomy in the early second trimester with complete resolution of hypercalcemia and pancreatitis. Neonatal course was unremarkable. To our best knowledge, this is a rare case when primary hyperparathyroidism and its complications are diagnosed in the first trimester of pregnancy. In conclusion, primary hyperparathyroidism is a rare life-threatening condition to the fetus and mother especially when associated with complications such as pancreatitis. Early therapeutic intervention is important to reduce the morbidity and mortality. Parathyroidectomy performed in the second trimester can be the only solution.

Learning points:

  • Learning how to make diagnosis of primary hyperparathyroidism in a woman during the first trimester of pregnancy.

  • Understanding the complications of hypercalcemia and be aware of the high mortality and sequelae in both fetus and mother.

  • Providing the adequate treatment in such complicated cases with coordinated care between endocrinologists and obstetricians to ensure optimal outcomes.

Summary

We report about a young female who developed an unusual and an aggressive phenotype of the MEN1 syndrome characterized by the development of a pHPT, malignant non-functioning pancreatic and duodenal neuroendocrine neoplasias, a pituitary adenoma, a non-functioning adrenal adenoma and also a malignant jejunal NET at the age of 37 years. Initial Sanger sequencing could not detect a germline mutation of the MEN1 gene, but next generation sequencing and MPLA revealed a deletion of the MEN1 gene ranging between 7.6 and 25.9 kb. Small intestine neuroendocrine neoplasias (SI-NENs) are currently not considered to be a part of the phenotype of the MEN1-syndrome. In our patient the SI-NENs were detected during follow-up imaging on Ga68-Dotatoc PET/CT and could be completely resected. Although SI-NENs are extremely rare, these tumors should also be considered in MEN1 patients. Whether an aggressive phenotype or the occurrence of SI-NENs in MEN1 are more likely associated with large deletions of the gene warrants further investigation.

Learning points

  • Our patient presents an extraordinary course of disease.

  • Although SI-NENs are extremely rare, these tumors should also be considered in MEN1 patients, besides the typical MEN1 associated tumors.

  • This case reports indicate that in some cases conventional mutation analysis of MEN1 patients should be supplemented by the search for larger gene deletions with modern techniques, if no germline mutation could be identified by Sanger sequencing.
