Intraoperative monitoring during awake craniotomy for glioblastoma resection in the second trimester of pregnancy. A case report and literature review.

OBJECTIVE

To demonstrate the feasibility and safety of awake craniotomy (AC) with intraoperative neurophysiological monitoring (IONM) for glioblastoma (GB) resection in a pregnant patient, ensuring preservation of neurological functions and fetal well-being.

METHODS

A 27-year-old gravida 2, para 1 woman presented at 19.4 weeks of pregnancy with severe headaches and a generalized tonic-clonic seizure. Imaging confirmed a malignant glioma, and an interdisciplinary team opted for AC with IONM to achieve maximal tumor resection while minimizing maternal and fetal risks.

RESULTS

Surgery was performed during the second trimester with successful gross total resection of the tumor. IONM strategies preserved neurological function, and fetal well-being was maintained. Postoperative evaluations showed no complications, and the patient was discharged in improved condition.

CONCLUSIONS

AC with IONM is a viable and safe surgical approach for GB resection during pregnancy. Tailoring the surgical plan by considering gestational age, maternal health, and fetal safety is crucial.

SIGNIFICANCE

This case highlights the importance of multidisciplinary management in optimizing outcomes for pregnant patients with GB, contributing valuable insights to the limited literature on neurosurgical interventions during pregnancy.
