Medullary Thyroid Carcinoma in Pregnancy: A Case Report and Literature Review on Maternal and Neonatal Outcome of Delayed Surgery Post-Partum

Abstract Thyroid malignancy poses a challenge especially when diagnosed during pregnancy. Although in papillary thyroid carcinoma, surgery can be safely delayed until the post-partum period, in medullary thyroid carcinoma, there is more urgency to treat. Here, we present a case of a 31-year-old female was diagnosed with medullary thyroid carcinoma during her third trimester. Diagnosis was made by aspiration cytology. Due to the patient’s condition, a CT scan was contraindicated and thus we were unable to make a complete assessment. A decision was made that the surgery was done after delivery, and when a complete assessment can be done. The surgery was successful and there were no complications both for the patient and her baby. In patients whom diagnosis of medullary thyroid carcinoma is made during the third trimester, it appears to be safe for mother and baby that surgery is done during the postpartum period.
