A 29-year-old woman with a prolactin microadenoma was under good control with bromocriptine (BCP) therapy until she became pregnant, when the treatment was stopped. During the third trimester of pregnancy the patient presented a unilateral visual loss and intermittent headaches. BCP was restarted and one week later she developed a complete ophthalmoplegia on the other side. The patient was submitted to an endoscopic transnasal transeptal resection of a hematoma and tumoral tissue in the pituitary region. One month after surgery, at 39 weeks of gestation, the patient spontaneously delivered a healthy girl weighing 3 kg, with an Apgar score of 9 and 10 at five minutes. This is the first case in the literature of a pregnant woman with second and third cranial nerve lesions, submitted to minimally invasive neuroendoscopic transnasal transsphenoidal approach in the third trimester of pregnancy.
