Postpartum Regression of a Presumed Cavernous Meningioma

Meningiomas are known to be more common in females than males. They are also known in rare cases to grow in size duringpregnancy, which can complicate its management. We describe a 31-year-old Caucasian woman who presented with blurring ofher vision and diplopia during the third trimester of her pregnancy. Magnetic resonance imaging (MRI) showed a small leftcavernous sinus meningioma. The patient was treated conservatively until her uncomplicated delivery. A postpartum MRI scanshowed complete regression of the suspected meningioma. Currently the patient is contemplating a further pregnancy.
