Meningocele with filiform connection

Case Report

The following images represent a case of meningocele with filiform connection. A 30-year-old woman G4P3 with non contributive medical history was admitted to the hospital at 27 weeks for the risk of premature labor. She had no previous ultrasound or biochemistry screening done during her ongoing pregnancy.

While performing the ultrasound on the admission, we revealed a round mass located at he occipital part of the cranium. This isolated finding was suggestive of a occipital meningocele with a filiform connection. There were no cerebral anomalies on the ultrasound examination. The fetal MRI was performed at 29 weeks of gestation and confirmed the primary diagnosis.

Patient delivered spontaneously at the 30 weeks of gestation due to a premature labor. Postnatal examination of the baby confirmed our prenatal ultrasound diagnosis of meningocele. There was no deficit on the neurological examination. The skin on the spine was intact. The surgery will be performed at the 6 months age of the neonate.
