  "abstract": "A 9 month old girl presented to the emergency department with a two day history of a few episodes of non-bilious non-bloody vomiting, diarrhoea, and intermittent distress with curling up of the legs. She had recovered from a viral upper respiratory tract infection one week earlier. The patient, who was breastfed and eating solid foods, also had reduced oral feeds for the past two days. There were no similar previous episodes. Micturition was normal and urine was not malodorous. Physical examination revealed tenderness in the right upper abdomen with hyperactive bowel sounds and no palpable mass. No skin rashes were seen. In view of her persistent symptoms, an urgent ultrasound of the abdomen was performed, which showed a mass in the right upper abdominal quadrant (fig 1).",
