Tuberculum sellae meningioma causing progressive visual impairment during pregnancy. Case report.

A 29-year-old woman in the 17th week of pregnancy presented with blurred vision and visual impairment of both eyes. Magnetic resonance imaging revealed a tuberculum sellae meningioma. Visual impairment progressively worsened, and surgical resection was performed in the 19th week of pregnancy without fetal heart monitoring. The intra- and postoperative courses were without complications. Her visual acuity and field almost fully recovered immediately after the operation. She delivered a healthy normal baby on the expected day.
