Intra- and interobserver variability of novel magnetic resonance imaging parameters for hip screening and treatment outcomes at age 5 years.

Background: The outcome measure of neonatal hip screening is usually the radiographic acetabular index.

Objective: To assess the feasibility of magnetic resonance imaging (MRI) without sedation and compare the utility of outcome parameters measured from MRI images.

Materials And Methods: The invitation for MRI scanning at 5 years of age was incorporated into follow-up for babies who had more than one ultrasound examination during treatment or surveillance.

Infantile chylothorax associated with staphylococcal paravertebral discitis.

We report an unusual case of chylothorax in an infant associated with a staphylococcal paravertebral abscess secondary to discitis affecting the thoracic spine. We discuss the initial presentation with sepsis and chylothorax and the delayed diagnosis of discitis. We also discuss the imaging features and treatment in this case.
