BACKGROUND: Diagnosis of hyperparathyroidism during pregnancy is rare becau
se symptoms are often moderate and similar to signs observed during normal
pregnancy. The gravity of such an association is probably underscored.
CASE REEPORT: The diagnosis of hyperparathyroidism was made at 9 weeks gest
ation in a young woman who declined surgery. She was seen again at 32 weeks
gestation for in utero fetal death. Nine months later she accepted surgery
and a parathyroid adenoma was removed.
DISCUSSION: Hyperparathyroidism during pregnancy is associated with signifi
cant morbidity with major maternal or fetal complications in 50% of the cas
es. Surgery during the second trimester of pregnancy is the treatment of ch
oice. if hyperparathyroidism is diagnosed in young women who desire pregnan
cy, surgery should be performed before advising pregnancy.
