Follicle stimulating hormone secreting pituitary adenoma: a challenging diagnosis

Madhuri Alap Mehendale, Nidhi Devendra Kalkal, Meenal Shailesh Sarmalkar, Arun Harishchandre Nayak


FSH secreting pituitary adenomas are relatively uncommon brain tumours and usually non-functioning. But in rare cases they produce ovarian hyperstimulation. We report a case of a 32 year old female P2L2, with amenorrhoea of 1 year, pain in abdomen and galactorrhoea since 6 months. Initially thought to be a simple prolactinoma with multicystic ovaries, but after thorough investigations to our surprise diagnosed to be a rare case of gonadotropin secreting pituitary adenoma. Patient was successfully managed by excision of the pituitary adenoma.
