Vestibular schwannoma unveiled by pregnancy: A case report and literature review.

ABSTRACT

BACKGROUND: Vestibular schwannomas - benign tumours originating from the vestibular nerve - are rare during pregnancy. The intricate interplay between the gravid uterus, maternal physiology and neoplastic growth imposes complexities that demand a careful and tailored approach. CASE REPORT This article reports a case of a pregnant woman in her 30 s diagnosed with a large vestibular schwannoma exhibiting brainstem compression, peritumoral oedema and cranial nerve encasement at 36 + 5 weeks of gestation. A multi-disciplinary team collaborated to devise a treatment plan considering the delicate balance between fetal well-being and the urgent need for intervention. A conservative approach involving close monitoring, corticosteroid therapy to manage peritumoral oedema, and detailed fetal assessments was initially employed. As the patient neared full term, a carefully planned caesarean section was performed, followed by a successful craniotomy to resect the vestibular schwannoma. Both the mother and the newborn showed favourable outcomes postoperatively. In addition, a literature review of cases of vestibular schwannoma in pregnancy was undertaken to inform optimal management strategies and enhance understanding of this complex scenario. CONCLUSION: This case highlights the complexity of managing vestibular schwannomas in pregnant women, and underscores the importance of a tailored, collaborative approach. The condition was resolved successfully, emphasizing the significance of timely diagnosis, meticulous planning and a patient-centred approach in these rare and intricate cases.
