Intracranial fetal teratoma: Case report and literature review.

Abstract

Fetal intracranial tumors are rare. Teratoma is the most common subtype, and it is particularly associated with poor prognosis. This article describes a case of fetal intracranial teratoma diagnosed at 31 + 6 weeks by ultrasound detection of macrocephaly and brain distortion. Due to the poor prognosis and after the advice of obstetricians and neonatologists, the couple decided to terminate the pregnancy. Feticide and cesarean section were performed under general anesthesia with difficult fetal extraction requiring cephalocentesis. In addition to the presentation of the case, a review of the cases published in the literature in the last 42 years was carried out. Together with two of our own cases, a total of 81 cases of intracranial fetal teratoma were collected. A statistical analysis was carried out with the different variables collected, the results of which could help clinicians when informing patients with pregnancies complicated by this type of tumor.
