Infants and children with neck masses frequently present to the radiologist for further evaluation. The role of the radiologist is to differentiate between conditions using imaging modalities such as ultrasound with colour Doppler, CT and MRI. Where appropriate, the radiologist will also stage lesions for management purposes and aid in guiding aspiration or biopsy. This paper presents a pictorial review of paediatric neck masses and their imaging features. Particular emphasis is applied to the anatomical site of the mass to aid in differential diagnosis. It must be emphasised that the radiological findings should always be interpreted in conjunction with the patient's age, the clinical history and the findings on physical examination.

Repeated episodes of diarrhoea were seen in 4 laboratory beagles after experimental renal surgery and feeding a modified diet. Small intestinal bacterial overgrowth (SIBO) was suspected by exclusion of other causes and measurement of plasma folate. SIBO was confirmed by quantitative duodenal bacteriology. Beagles with SIBO can show no clinical signs, experimental stress and dietary change may have been reasons why these 4 beagles exhibited clinical signs with SIBO. Despite normal gut histology an increase in gut permeability was found using sugar absorption tests. This increased permeability had the potential to cause variations in drug absorption during experimental studies.
