Hypothesis
Can the 'Lasso sign' be used as an early sonographic indicator for diagnosing posterior meningocele?
Conclusion
The detection of the 'Lasso sign' may indicate the diagnosis of posterior meningocele, which generally has no long-term effects.
Supporting Evidence
- The 'Lasso sign' was identified during a routine anatomical scan.
- The prenatal follow-up showed no signs of tethered cord.
- The infant's neurological examinations at two and four months were unremarkable.
Takeaway
Doctors can sometimes see a special sign on ultrasounds that helps them find a type of back problem in babies before they are born.
Methodology
The case was diagnosed using 2D and 3D ultrasound during a routine anatomical scan.
Limitations
Pathological evaluation was not performed, and the diagnosis relied on ultrasound and clinical examination.
Participant Demographics
A healthy 29-year-old woman at 15 weeks of gestation.
