Imaging of nontraumatic acute hip pain in children: multimodality approach with attention to the reduction of medical radiation exposure.

Nontraumatic acute hip pain in children is common. However, the presentation and etiology is variable, including difficulty with weight bearing and abnormal gait. Barriers in communication, multiple possible etiologies, and age-specific anatomical variations of the pediatric hip make the evaluation of hip pain in children a difficult clinical diagnosis.

Pectus excavatum: current imaging techniques and opportunities for dose reduction.

Pectus excavatum (PE) is the most common congenital chest wall deformity in children. It affects 1 in every 300-1000 live births with a male to female ratio of 5:1. Most of the patients present in their first year of life.

Metaphyseal fragmentation with physiologic bowing: a finding not to be confused with the classic metaphyseal lesion.

Objective: The purpose of this study was to describe the varied appearances of metaphyseal fragmentation associated with physiologic bowing and to estimate their frequency in children undergoing radiographic evaluation.

Conclusion: The results of this study suggest that metaphyseal fragmentation is occasionally encountered in children with physiologic bowing. Results of a systematic imaging assessment should minimize confusion of this innocent radiologic alteration with the classic metaphyseal lesion of child abuse.

Congenital adrenocortical adenoma: case report and review of literature.

Congenital ardrenocortical neoplasms are exceedingly rare. Our review of the medical literature revealed 23 reported cases of adrenocortical neoplasm including this one. Eighteen of these cases were adrenocortical carcinoma and four were grouped as adrenocortical tumor.
