| Summary points: | A 30-year-old, nulliparous, pregnant, Nigerian (33 weeks) woman presents with a 2-year history of blurry vision, headaches, and vomiting. After physical examination, neurological investigations, and computed tomography scan of the brain, a diagnosis of pituitary macroadenoma was made and a plan for surgery after delivery was made. The patient was put on bromocriptine to reduce tumour size. Premature labour at 35 weeks resulted in caesarean delivery, and she was managed in the intensive care unit where oral bromocriptine was resumed. She developed accelerated hypertension with encephalopathy and died due to 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 haemorrhage in a patient with a macroadenoma. |
