Case ReportsSymptomatic caval penetration by a Celect inferior vena cava filter.
We report a case of penetration of the inferior vena cava (IVC) by all four primary struts of a Celect caval filter in a 17-year-old girl with Klippel-Trénaunay syndrome. The girl presented with acute lower abdominal and right leg pain 17 days after filter insertion. An abdominal radiograph demonstrated that the filter had moved caudally and that the primary struts had splayed considerably since insertion. ⋯ There was a small amount of retroperitoneal hemorrhage. The surrounding vessels and viscera were intact. The filter was subsequently retrieved without complication.

Multicenter StudyRadiation exposure from pediatric head CT: a bi-institutional study.
Medical radiation from CT should be kept as low as reasonably achievable (ALARA), particularly in young patients. ⋯ The radiation dose from head CT in children as defined by the normalized ED was highest in the youngest children and varied significantly between institutions in this bi-institutional study.

Validation of US as a first-line diagnostic test for assessment of pediatric ileocolic intussusception.
From the early 1980s onward, US has been considered a possible primary modality to assess patients for ileocolic intussusception. Since 2001, our institution has routinely used US to assess patients for ileocolic intussusception. ⋯ US is a sensitive and specific test for detecting ileocolic intussusception and should be utilized as a first-line examination for assessment of possible pediatric intussusception.

Case ReportsHorseshoe lung associated with left-lung hypoplasia, left pulmonary artery sling and bilateral agenesis of upper lobe bronchi.
Horseshoe lung, a rare congenital anomaly, is almost always associated with unilateral (usually right-sided) lung hypoplasia, and, in most cases, in conjunction with the scimitar syndrome. We present an 8-month-old boy with horseshoe lung associated with left-lung hypoplasia, left pulmonary artery sling and bilateral agenesis of the upper lobe bronchi, diagnosed by multidetector CT (MDCT) imaging. ⋯ A hemivertebral anomaly of the seventh cervical vertebra was incidentally detected. MDCT with high-quality multiplanar and three-dimensional reconstructions is a noninvasive and rapid technique for detecting the complex combination of vascular, tracheobronchial and parenchymal anomalies, and any potential bone anomalies, in one imaging study.
