Objectives: After studying the article titled “Sonographic Criteria for Diagnosing: Jarcho-Levin Syndrome,” you will be able to:

1. Describe the sonographic signs of Jarcho-Levin syndrome

2. Explain the difference between spondylothoracic dysostosis (STD) and spondylocostal dysotosis (SCD) forms of Jarcho-Levin syndrome

3. Discuss differential diagnoses for Jarcho-Levin syndrome

1. Sonographic signs of Jarcho-Levin syndrome include:

2. Abnormal biparietal diameter (BPD)

3. Fused posterior ribs

4. Short limbs

Spondylothoracic dysostosis (STD):

Is an autosomal dominant form of the Jarcho-Levin

Has a higher incidence in people of Spanish heritage

Is a milder form of the Jarcho-Levin

Has a good prognosis if surgical intervention is used

Spondylocosal dysostosis (SCD):

Is a more severe form of Jarcho-Levin syndrome

Is easier to diagnose in utero than the STD form of the disease

Occurs more often in people of African descent

Is characterized by vertebral and intrinsic costal anomalies

Costovertebral segmentation defects with mesomelia is a differential diagnosis of Jarcho-Levin syndrome and presents with:

Normal vertebrae

Hemivertebrae

Spina bifida

Anencephaly

In this case study, the fetalgram demonstrated:

Findings consistent with MRI and CT studies completed before birth

Seven ribs on the left and five ribs on the right

The entire skeleton of the infant in consecutive radiographs

Was not helpful in diagnosing Jarcho-Levin syndrome
