Hepatic injury from blunt trauma in children: follow-up evaluation with CT.
Because CT is now used to assess the extent of abdominal injury after blunt trauma, children with hepatic injury often can be treated nonsurgically. We used a CT grading system to evaluate the frequency of complications and the time course of healing in children with hepatic injury from blunt abdominal trauma. ⋯ CT grading of acute hepatic injuries is useful for estimating the time course of healing. Although mild and moderate hepatic injuries heal relatively quickly, severe hepatic injuries take months to resolve. Follow-up CT scans to verify complete hepatic healing should be obtained 3 months after mild injuries, 3-6 months after moderate injuries, and 9 months after severe injuries.

Periportal low density on CT in patients with blunt trauma: association with elevated venous pressure.
We postulated that the CT finding of periportal low density after acute blunt trauma of the abdomen or pelvis results from elevated central venous pressure caused by rapid expansion of intravascular volume during IV resuscitation or by other trauma-related pathologic changes. ⋯ The CT finding of periportal low density after blunt abdominal trauma indicates acute elevation of central venous pressure and does not by itself signify hepatic parenchymal injury, as has been previously reported.

Partial anomalous pulmonary venous drainage of the left upper lobe vs duplication of the superior vena cava: distinction based on CT findings.
Partial anomalous pulmonary venous drainage of the left upper lobe and duplication of the superior vena cava have similar appearances on CT scans. The purpose of this study was to review their appearances and provide guidelines for differentiating between them. ⋯ Careful analysis of the CT scans with particular attention to these two features allows differentiation between partial anomalous pulmonary venous drainage of the left upper lobe and duplication of the superior vena cava.
