A 3-year-old child with abdominal pain and fever.

CASE HISTORY A previously healthy 3-yr-old male was evaluated for fever and abdominal pain, and a chest radiograph was performed (fig. 1). A detailed history was collected and the parents reported the child having a ‘‘distended abdomen’’ from a few months old. They had the impression he was a calm child, less inclined to run and play than his peers. In the previous year, two episodes of bronchitis had prompted skin-prick tests, showing sensitisation to trees, dogs, cats, Alternaria alternata and Aspergillus fumigatus. The child’s history was otherwise uneventful for respiratory symptoms, such as tachypnoea, persistent cough, wheezing or chest pain.
