Prolactinoma is the most common secreting pituitary adenoma. It is typically 
diagnosed in women of reproductive age and is common cause of infertility. 
Currently the treatment of choice is pharmacotherapy with dopamine agonists, 
whereas surgical treatment is reserved for a selected group of patients. 
Pituitary-tumor apoplexy is a rare, life-threatening condition associated with 
significant morbidity and mortality. The authors present the case of a 
25-year-old woman with prolactinoma treated with dopamine agonist. In course of 
such a treatment the patient became pregnant. The bromocriptine was gradually 
withdrawn. In the 14th week of pregnancy she was admitted for symptoms 
suggesting pituitary tumor apoplexy. The treatment with bromocriptine was 
reinitiated. In the 20th week of pregnancy further deterioration of the 
patient's neurological condition and visual-field abnormalities were observed. 
The patient was qualified for surgical treatment - selective transsphenoidal 
adenomectomy. The successful surgery led to improvement of neurological 
condition. The early postoperative PRL level decreased significantly and 
hormonal function of the pituitary was preserved. The pregnancy ended in 38th 
week with a caesarean section. Endocrinological evaluation conducted after the 
uneventful delivery confirmed normal function of the pituitary. Magnetic 
resonance imaging (MRI) did not reveal tumor re-growth. The patient is kept 
under constant medical care. In this case study the authors discussed 
therapeutic management and reviewed literature regarding gestational 
pituitary-tumor apoplexy with particular emphasis on surgical treatment.
