Management of pituitary adenoma with mass effect in pregnancy: a case report

A middle aged primigravida was managed at the University of Nigeria Teaching Hospital, Enugu, Nigeria for a pituitary macroadenoma. She was admitted at 33 weeks gestational age following a history of blurred vision and generalized headache, worse on bending down.

After neurological consultation and investigations, a diagnosis of pituitary macroadenoma with mass effect was entertained. A plan for neurosurgery after delivery was made and the patient put on bromocriptine to reduce tumour size.

Premature labour at 35 weeks resulted in caesarean delivery of a live baby. She was managed in the intensive care unit for three days where oral bromocriptine was resumed before she was transfer to the postnatal ward.

Within ten hours of the transfer, she developed accelerated hypertension with encephalopathy and had a cardiac arrest shortly afterwards. This rare case highlights both the possible role of bromocriptine as a cause of postpartum hypertension and the possible development of a sudden catastrophic intramoural infarction or hemorrhage (pituitary apoplexy) in a patient with a macroadenoma.
