Meningioma regression following depot medroxyprogesterone acetate withdrawal: a case series

Background

Progesterone signalling is a key determinant of meningioma behaviour, particularly in skull base tumours. Cyproterone acetate-associated meningiomas stabilise or regress after withdrawal Whether similar reversibility follows cessation of depot medroxyprogesterone acetate (DMPA), a widely used long-acting injectable contraceptive, is poorly characterised.
