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

Abstract

BackgroundVestibular 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 reportThis 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. ConclusionThis 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.
