Chest radiographic findings in children with asplenia syndrome.

Background: Early diagnosis of asplenia syndrome is important because prophylactic antibiotic and proper vaccination will prevent serious infection. Most children with asplenia syndrome present with symptoms of congenital heart disease. Chest X-ray is usually the first line imaging modality. Objective: Define useful findings in chest radiograph that could suggest the diagnosis of asplenia syndrome. Methods: Chest radiographs of pediatric patients who had asplenia syndrome diagnosed between January 1, 2002 and June 30, 2008 in a single institute were retrospectively reviewed for the positions of the visceral organs in the chest and abdomen. Results: Three hundred seventy one chest radiographs of 30 patients were reviewed. The mean age at diagnosis was 3 years old. Asplenia was diagnosed by ultrasound in 27 patients, by CT scan in two patients, and by damaged red blood cell scintigraphy in one patient. Six important findings detected from chest radiographs were, 1) bilateral minor fissures, 16 cases (53%), 2) bilateral eparterial bronchi, 16 cases (53%), 3) ipsilateral side of stomach and liver, 12 cases (40%), 4) ipsilateral side of minor fissure or eparterial bronchus and stomach, 10 cases (33%), 5) symmetrical transverse lie of the liver, nine cases (30%), and 6) contralateral side of minor fissure or eparterial bronchus and the liver in seven cases (23%). All except two patients (93%) had at least one of the above findings. All patients had congenital heart diseases. Most of the heart diseases were pulmonary atresia or pulmonary stenosis (88%) and single ventricle (85%). Conclusion: Chest radiographs have high sensitivity in suggesting the diagnosis of asplenia syndrome, when detecting one or more of the above findings, particular in patients with congenital heart disease and decreased pulmonary vasculature.

Regression of a cervical spinal mass following highly active antiretroviral therapy (HAART) in child with advanced human immunodeficiency virus (HIV) disease.

This report documents a case of infiltrating cervical spinal mass, most likely a spinal tumor, in a girl with HIV infection that regressed following HAART and without treatment of the tumor or any anti-infectives.

Child abuse: radiographic findings at King Chulalongkorn Memorial Hospital.

OBJECTIVE: To describe radiographic findings in physically abused children. MATERIAL AND METHOD: The physically abused children diagnosed in King Chulalongkorn Memorial Hospital from 1998 to 2002 were retrospectively reviewed of medical records and radiographic imaging. RESULT: Eighteen of 30 physically abused children had positive radiographic findings and 15 of 18 were related to head injury. Subdural hematomas and skull fractures were the two most common findings found in 11 cases and 9 cases respectively. Seven of 11 cases of head injury had retinal hemorrhage. Fractures other than the skull were detected in 6 patients, located at the long bones, ribs and spines. The abused children with positive radiographic findings were more commonly found in younger infants and mucocutaneous lesions might be absent. CONCLUSION: Inflicted head injury was the most common radiographic findings in the present series. Shaking-impact mechanism was likely to play a significant role in this group of patients.
