Meningioma during pregnancy: what can influence the management? A case series and review of the literature

Abstract

Purpose: Meningioma is a benign tumor, more frequent in female population. During pregnancy, distinguishing a meningioma from other common conditions presenting with similar symptoms (headache, vomiting, visual impairment) is challenging. Moreover, the management must consider not only maternal but also fetal health. The rarity of the condition does not allow to define the features to which look in order to stratify the risk for the need of surgery during pregnancy. We reported three cases of meningioma in pregnant women treated at our department and reviewed those previously reported in the literature. The aim of this review is to evaluate which factors are more determinant in such management.

Methods: Electronic databases were searched from year 2000 until June 2020, to identify clinical studies on management of meningioma diagnosed during pregnancy. The primary outcome was surgical timing. Secondary outcomes were delivery methods, maternal and neonatal outcomes.

Results: Surgery after pregnancy is more frequently performed in PR + tumor (p-value 0.038) and with HA (p-value 0.0445), as well as in meningioma diagnosed during the third trimester, compared to those diagnosed before (p-value 0.0012). Surgery during pregnancy was more frequent in patients with visual loss (p-value 0.006). No significant differences were found in surgical management, according to age, WHO grade, tumor location, lesion diameter and ER positivity. Delivery method is independent from both hormonal receptor status and main symptoms, but women who had neurosurgery during pregnancy delivered more frequently with spontaneous vaginal delivery (p-value <0.01).

Conclusion: The decision regarding surgical timing of meningioma diagnosed during pregnancy depends on PR + and impending symptoms as visual loss or headache. It seems that timing of neurosurgery does not affect the delivery method. A multidisciplinary approach is always useful to perform a rapid and appropriate diagnosis and to better evaluate pros and cons of surgery during pregnancy and following management both for maternal and fetal wellness.
