Bilateral anterior sacral meningoceles in pregnancy without sacral anomaly: a case report of a rare clinical entity

This report describes a 32-year-old primigravida diagnosed with bilateral anterior sacral meningoceles without bony defect of the sacrum during pregnancy. The patient remained asymptomatic throughout the pregnancy, with regular monitoring via transvaginal ultrasound and MRI. An elective cesarean section was planned at 38 weeks. However, the patient presented in obstructed labor at 42 weeks and underwent an emergency cesarean section, resulting in the birth of a healthy infant. This case is unique as it involves bilateral anterior meningoceles without sacral anomalies. Anterior sacral meningoceles are rare findings in pregnancy. Anterior sacral meningoceles are either congenital with bony defect of the sacrum or acquired lesions due to connective tissue disorders characterized by the herniation of the meninges through the sacral foramina. In pregnancy, these lesions pose unique challenges due to potential complications such as rupture, infection, or obstructed labor. Management strategies vary, and individualized approaches with close monitoring and patient counseling are crucial in determining the appropriate mode and timing of delivery.
