99mTc-DMSA scanning to diagnose pyelonephritic scarring in children.

99mTechnetium-labeled dimercaptosuccinic acid (99mTc-DMSA) scanning provides superior quality images of renal parenchymal detail, which makes it highly sensitive for the diagnosis of pyelonephritic scarring. Unlike most other imaging techniques, radionuclide scanning is not affected by bowel gas or bony structures overlying the kidneys. This makes it particularly useful in children. Furthermore, renal scarring can be demonstrated by 99mTc-DMSA even before the classic gross anatomic and radiologic changes are present. The use of 99mTc-DMSA scanning in over 300 children has demonstrated its benefits and advantages over standard radiographic techniques.

The distended neonate.

A prospective study, followed by a retrospective audit, was made of the radiographs and clinical features of 225 consecutive neonates with abdominal distension presenting during a period of 4 years. More than one major cause for the distension was found in a third of cases. Excluding cases of ano-rectal atresia, diagnostic difficulties were encountered in 31% of cases and, occasionally, the diagnosis was revised several times as investigations proceeded. Neuhauser's sign of 'bubbly' meconium is unreliable, being found in cases of meconium ileus, ileal atresia, Hirschsprung's disease and necrotising enterocolitis. Concomitant small-bowel atresia should be suspected in all cases of meconium ileus; intestinal malrotation should be considered in association with duodenal and intestinal atresias. In the absence of an obvious anatomical defect, it is difficult to differentiate between the various causes of functional obstruction by radiological means alone and all such infants should be referred to a specialised centre for intensive investigation and treatment. Very often, the skills of a neonatologist, paediatric surgeon and, especially, an experienced pathologist will be required in addition to those of the radiologist.

Pulmonary actinomycosis in children.

The radiological features of three cases of pulmonary actinomycosis in children are presented. Two of the cases had the classical roentgen features of chronic consolidation with overlying rib periostitis. The third had non specific consolidation but demonstrated extension through the diaphragm. Two of our cases were mentally subnormal children in institutional care. Their pulmonary pathology is almost certainly attributal to poor dental hygiene, a constant problem in this group of children. Hence, although pulmonary actinomycosis is rare in the general populus, we suggest it might be suspected more often in the subnormal group when chronic consolidation is present.

The appearances of artefacts on lower limb phlebograms.

The various artefacts that may be encountered in phlebograms and which may be confused with thrombus are described. Methods of avoiding these pitfalls are discussed. the conclusions are based on over 2500 phlebograms carried out for suspected deep vein thrombosis.

CT scanning in meningitis.

Twelve paediatric cases of acute meningitis were reviewed retrospectively. Findings on CT scan were compared with the clinical course and resulting neurological sequelae. Complications detected by CT scanning include subdural effusion, empyema, hydrocephalus, cerebral atrophy, oedema and infarction. The CT scan results adequately correlated with neurological signs in most cases. Infarction was a reliable indicator of neurological sequelae. Cerebral atrophy alone, however, did not correlate well with the clinical sequelae.

Modern approach to the diagnosis of osteomyelitis in children.

Osteomyelitis in childhood is common and causes serious morbidity. X-rays and bone scans are the primary tools of radiological investigation. Other imaging techniques, including ultrasound, computed tomography, magnetic resonance imaging and white cell scintigraphy have a valuable role in difficult cases.
