Hormonal therapy for fertility and huge meningioma: a purely random association?

Sexual hormones have been related to the growth of meningiomas, also due to the almost constant expression of hormonal receptors by tumoral cells. A case of a woman with previous history of multiple treatment for infertility, harboring a huge meningioma is here described. The tumor was surgically resected and the immunohistochemical examination revealed a high expression of progesterone receptors on tumoral cells surface. A putative role of past progesterone administration in the growth of meningioma has been hypothesized. Particular caution should be paid whenever adopting sexual hormonal therapy, especially for fertility. A radiological examination (ideally MRI) could be advised before starting therapy, in order to rule out any intracranial meningioma.
