Giant myelomeningocele presenting as obstructed labor: a rare cause of dystocia

Myelomeningocele is a severe open neural tube defect resulting from failure of neural tube closure during early embryogenesis. Although commonly diagnosed antenatally, large lesions may occasionally present intrapartum and cause obstructed labour. We report a case of a 25-year-old woman presenting in advanced labor with obstructed delivery. Antenatal ultrasonography revealed a large cystic lumbosacral mass with polyhydramnios. In view of obstructed labor, an emergency cesarean section was performed. Intraoperatively, a giant lumbosacral cystic mass was identified, causing obstruction at the pelvic brim. Aspiration of cystic contents facilitated delivery. Postnatal evaluation confirmed the diagnosis of giant myelomeningocele. Giant myelomeningocele is a rare but important cause of obstructed labor. Early antenatal diagnosis, regular antenatal care, and timely referral are essential to prevent maternal and neonatal morbidity.
