Background:
Meningiomas are slow-growing tumors that may present in pregnancy because of accelerated growth. We present the case of a recurrent meningioma in two separate pregnancies in the same woman.
Case:
A 35-year-old woman presented at 30 weeks of gestation with limb weakness, vomiting, and a progressive decreased level of consciousness with an enlarging forehead mass. Imaging revealed a massive extra-axial exophytic tumor. An emergency craniotomy was performed, complicated by massive blood loss. Final pathology showed a grade I meningioma positive for progesterone receptors. Maternal-fetal outcome was good, with return of normal neurologic status and elective delivery at 38 weeks of gestation.
Conclusion:
Pregnancy is associated with accelerated meningioma growth and recurrence. Treatment during pregnancy is possible and requires a multidisciplinary approach.
