RESUMO
The diagnosis of malignancy, particularly brain tumors, in pregnancy is uncommon but poses a complex dilemma for the management of both the patient and her fetus, as the interplay of disease with the physiological state of pregnancy affects both outcomes. The routine evaluations (symptomatology, imaging, and hormonal assessments) and treatments (surgery, radiation therapy, and chemotherapy) that are commonplace in brain tumor management may need to be omitted or modified keeping in mind the risk to offspring. Multidisciplinary care and extensive prenatal and perinatal counseling and monitoring are essential. In this review, we discuss the available data addressing these issues and factors which may affect considerations of therapeutic abortions, changes in surgical or medical practices, and outcomes thereof.
