  • Title: Atypical presentation of pheochromocytoma as part of multiple endocrine neoplasia IIa in pregnancy.
    Author: Ahn JT, Hibbard JU, Chapa JB.
    Journal: Obstet Gynecol; 2003 Nov; 102(5 Pt 2):1202-5. PubMed ID: 14607057.
    Abstract:
    BACKGROUND: Pheochromocytoma in pregnancy is extremely dangerous, especially when unrecognized, and can present alone or as part of a multineoplastic syndrome. Hypertension, its hallmark, is not present in all cases, particularly in women with multiple endocrine neoplasia type IIa. CASE: We report a gravida with undiagnosed multiple endocrine neoplasia IIa who presented initially with peripartum cardiomyopathy but was diagnosed with an underlying pheochromocytoma. Once recognized and treated with appropriate alpha-adrenergic blockade, her condition reversed quickly. CONCLUSION: Physicians should be aware that pheochromocytoma can present as cardiovascular collapse rather than just hypertension.
