妊娠期间，脑膜瘤属于罕见的良性肿瘤。由于其尺寸可能迅速变化，脑膜瘤可能会对母体和胎儿产生风险。本研究报道了一例34岁孕妇患有嗅沟脑膜瘤的病例，其在妊娠第29周时视力受损、嗅觉丧失和味觉异常症状加重。磁共振成像显示嗅沟脑膜瘤。为避免因颅内压迫现象导致临床病情恶化，患者在早产的情况下接受剖腹产手术。脑部计算机断层扫描支持了诊断。手术干预在分娩后第3天进行。临床过程顺利，垂体交叉疾病在接下来的2个月内得到改善。妊娠期的脑膜瘤可能带来独特的挑战，并具有广泛的临床表现。治疗母体脑膜瘤可能复杂，需要多学科的协同治疗。治疗决策很大程度上取决于肿瘤的大小和位置、症状的存在、妊娠年龄和胎儿的健康状况。需要进一步研究以增进对潜在机制的理解，并改进这种罕见情况的治疗方法。© 2023 The Author(s).

Meningiomas are rare benign tumors during pregnancy. They can put both the mother and the fetus at risk because rapid changes in size may occur. The study reports a case of olfactory groove meningioma in a 34-year-old pregnant woman with visual impairment, anosmia, and dysgeusia that increased in severity during the 29th week of gestation. Magnetic resonance imaging showed an olfactory groove meningioma. The patient underwent a preterm cesarean section to avoid the worsening of the clinical condition due to intracranial compression phenomena. A computed tomography scan of the brain supported the diagnosis. The surgical intervention occurred on the third day after delivery. The clinical course was uneventful and the chiasmal syndrome improved in the following 2 months. Meningiomas in pregnancy may present unique challenges and have a wide array of clinical presentations. Management of maternal meningiomas can be complex and requires a multidisciplinary approach. The treatment decision largely depends on the size and location of the tumor, the presence of symptoms, gestational age, and fetal well-being. Further research is needed to enhance the understanding of the underlying mechanisms and improve management approaches for this rare condition.© 2023 The Author(s).
