Background
Pelvic radiographs are commonly performed in children presenting with hip pain. Pelvis is also included in routine abdominal radiographs performed for other reasons. Familiarity with appearance of pelvic bones at various stages of development is important to identify pathology. Also knowledge of various pathologies that can affect the pelvic bones in children and their imaging appearance is important to make the correct diagnosis and to suggest appropriate further imaging.

Educational Goals / Teaching Points
This exhibit aims to discuss embryology, normal development and appearance of pelvic bones on radiographs;.list common and uncommon pathologies that can be seen on pelvic radiographs in pediatric patients; describe and illustrate imaging features of commonly encountered and uncommon pathologies that can affect the pelvic bones in children; and describe and illustrate normal variants that can be confused with pathology.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Various congenital, developmental, traumatic, infectious and neoplastic pathologies can affect the pediatric pelvic skeleton and can be identified on pelvic radiographs obtained for hip pain or incidentally identified on abdominal radiographs obtained for other reasons. Pelvic radiographs in children are different from adults due to developing nature of the skeleton. Familiarity with normal appearance of pelvic bones and proximal femora at different ages during childhood is important. Identification of normal variants is important so that they are not mistaken for pathology. A thorough knowledge of commonly encountered and uncommon pathologies will help the radiologists in making the correct diagnosis and suggest appropriate further workup when necessary.

Conclusion
Several pathologies can affect the developing pediatric pelvic skeleton. Knowledge of normal radiographic appearance of developing pelvic bones, normal variants, and common and uncommon pelvic bone pathologies seen in children is important to make the correct diagnosis.
