1. A 4-year-old girl was brought to the emergency department by her parents on a Sunday afternoon. Because of a clinical history of right upper quadrant pain and trace hematuria, abdominal radiographs were obtained. What do they show?

An otherwise healthy 9-month-old girl was brought to the emergency department (ED) by her parents who reported a 12-hour history of nonbloody, nonbilious emesis. The patient had a mildly increased temperature and appeared to be dehydrated.

These images were obtained from a 5-month-old boy who was brought to the emergency department (ED) by his parents who noted new-onset rectal prolapse. The prolapse promptly recurred following initial successful reduction under sedation in the ED. A surgical consultation was obtained and abdominal radiographs were requested.

1. The chest radiographs (Figure 1) of a 9-year-old child reflect the classic findings of a particular disease. Among other findings, the size of the patient's heart is_____?

It is always tempting to find something on the chest radiograph that might explain a patient's symptoms. In this instance, however, there are no pathological findings in the lung parenchyma.
