Case ReportsPerforation associated with barium enema in acute appendicitis.
A child with the suspected diagnosis of atypical acute appendicitis underwent a diagnostic barium enema. The study was complicated by perforation with leakage of a large amount of barium into the peritoneal cavity. The complex hospital course that resulted has prompted us to reevaluate the barium enema in the diagnosis of appendicitis and review the literature for contraindications. We conclude that this particular complication is extremely rare and that barium enema still has a part to play in some patients where the clinical diagnosis is uncertain.

Case ReportsCystic retroperitoneal lymphangioma: CT, ultrasound and MR findings.
A case of cystic retroperitoneal lymphangioma complicated by hemorrhage is reported in a 7-year-old boy who presented with an abdominal mass. The mass which was partially obstructing the ureter was successfully resected. The imaging findings with emphasis on MR features are described.

While trauma is still the leading cause of death in the pediatric age range, it is surprising how little the CT appearances of pediatric chest injury have been investigated in the literature. We have reviewed the CT findings of blunt chest trauma in 44 children for whom chest CT examinations were requested to investigate the extent of intrathoracic injury. We noted a propensity for pulmonary contusions to be located posteriorly or posteromedially, and for them to be anatomically nonsegmental and crescentic in shape. ⋯ Children demonstrating findings incidental to the actual injury yet important to the subsequent therapy are also presented. We conclude that, in the event of clinically significant blunt chest trauma, the single supine chest examination in the trauma room is insufficient to adequately identify the extent of intrathoracic injury. With the exception of concern for aortic injury for which aortography is indicated, a dynamically enhanced CT scan of the thorax should be performed as clinically significant findings may result in altered therapy.

Review Case ReportsSonographic diagnosis of portal venous gas in two pediatric liver transplant patients with benign pneumatosis intestinalis. Case reports and literature review.
Pneumatosis Intestinalis (gas in the bowel wall) is uncommon in children and is associated with a number of clinical conditions most notably necrotizing enterocolitis in sick neonates. We observed portal venous gas on sonography and benign pneumatosis intestinalis on abdominal radiography in two children who had recently undergone liver transplantation. Asymptomatic portal venous gas and pneumatosis intestinalis has not been described previously in pediatric liver transplant patients. It is important to recognize the sonographic appearance of portal venous gas since sonography is the imaging modality most frequently utilized for monitoring the allograft post liver transplantation.
