ABSTRACT
A macroprolactinoma recurred in a 25-year-old lady, who had initially presented with inability to conceive, secondary amenorrhea, galactorrhea and persistent headache. She was diagnosed as a patient of pituitary macroadenoma of 1.7 cm with elevated serum prolactin level. She was given Bromocriptine, which normalized her menstruation as well as the prolactin level followed by conception during treatment. Pregnancy remained uneventful till 27 weeks when she developed severe headache and total loss of vision from left eye and partial from right eye at 27 weeks. MRI showed enlargement of macroadenoma upto 2.5 cm with compression on optic chiasma. Transsphenoidal adenectomy was performed. After surgery visual field defect improved but plasma prolactin level remained elevated. She delivered vaginally at 39 weeks. Later, treatment with Bromocriptine [15 mg/day] failed to keep prolactin level normal and Lisuride hydrogen [0.8 mg/day] reduced the prolactin levels
