Abstract
Background
Pheochromocytoma manifesting during pregnancy is uncommon but it is responsible for a high maternal and fetal mortality rate, especially when unrecognized. Most cases of pheochromocytoma are sporadic but they can be part of hereditary autosomal dominant syndromes.
Case
We describe a case of bilateral pheochromocytoma in a term-pregnant patient with a previous history of medullary thyroid carcinoma (MTC). Her genetic study revealed a heterozygous mutation, c.1900T>C, in the RET proto-oncogene which confirmed the diagnosis of multiple endocrine neoplasia type 2A (MEN2A). Unrecognized, the tumors caused a crisis with fatal outcome in the mother during the postpartum period. This event might have been prevented if the tumor had been detected previously.
Conclusion
MEN2A affected pregnancy is an unusual condition. This syndrome should be suspected when a pregnant patient has a history of MTC. Early detection and appropriate management can prevent serious maternal and fetal complications. We also reviewed the literature of MEN2A-affected pregnancies.
