The diagnosis of occult elbow fracture in children is often challenging due to equivocal or negative repeated radiographic findings. ⋯ Posttrauma elbow joint effusion in children is not always related to a cortical fracture. US appears to be a reliable, accurate, widely available and effective low-cost tool in these cases. The diagnostic clue is the detection of a lipohaemarthrosis in the articular recess.

Comparative StudyWhole-body MR imaging with the use of parallel imaging for detection of skeletal metastases in pediatric patients with small-cell neoplasms: comparison with skeletal scintigraphy and FDG PET/CT.
In pediatric patients with small-cell tumors, there is an increasing demand for accurate and early detection of skeletal, especially bone marrow, metastases as new treatment protocols are introduced. Whole-body MR imaging (WB-MR) and (18)F-fluorodeoxyglucose PET/CT (FDG PET/CT) are new promising imaging methods that can detect metastases before osteoblastic host response occurs, which is the basis for detection of metastases by skeletal scintigraphy (SSC). ⋯ Our results suggest that WB-MR and FDG PET/CT studies are robust imaging modalities for screening for skeletal metastases, and are far more accurate than SSC. The lack of radiation is an additional advantage of WB-MR, especially in the pediatric population.
