Optimizing US examination to detect the normal and abnormal appendix in children.
US detection of a normal appendix can safely rule out appendicitis. However, there is a wide range of accuracy in detection of a normal appendix. ⋯ US scanning according to the potential positions of the appendix was useful in the detection of normal appendices in children suspected of having appendicitis.

Comparative StudyWhole-body MRI of Langerhans cell histiocytosis: comparison with radiography and bone scintigraphy.
In Langerhans cell histiocytosis (LCH) evaluation of the extent of disease is one of the major predictors of patient outcome. Historically this is undertaken using plain radiography and bone scintigraphy. Recently, whole-body (WB) MRI has been reported to be useful in detecting skeletal and extraskeletal metastases in both adults and children. ⋯ WB MRI is a useful initial and follow-up diagnostic method to assess the extent of LCH because WB MRI not only identifies more skeletal lesions of the disease than do plain radiography and bone scintigraphy, but also detects extraskeletal lesions of the disease.

Muscle inflammation is a relatively common pathological process in childhood. The diagnosis of the underlying cause relies on an appreciation of the pattern of clinical features, as well as the results of biochemical, histological and radiological investigations. Often the clinical and biochemical features are non-specific and insensitive. ⋯ Some of the imaging protocols needed to investigate a variety of muscle and soft-tissue inflammatory conditions in childhood are reviewed in this article. Those features that are helpful in narrowing the differential diagnosis are indicated and a logical approach to the investigation of affected children is provided. The value of MR imaging is highlighted.

Case ReportsPneumorrhachis secondary to traumatic pneumomediastinum in a child.
Pneumorrhachis (air within the spinal canal) is rare, and even more so in the paediatric population. We report a case in a 4-year-old boy that resolved spontaneously on treating the underlying traumatic pneumomediastinum, and discuss the causes, mechanism and implications of this condition.
