A common case of gastroenteritis in a child followed by an axial torsion of Meckel diverticulum: a rare and unusual complication.

A 1-year-old boy presented at our hospital with common gastroenteritis symptoms such as fever, vomiting and diarrhoea. Clinical and laboratory findings were normal. An emergency ultrasound examination was performed and excluded abdominal complications. After 2 days of complete regression of symptoms, the patient began to vomit again, diarrhoea stopped with a sudden worsening of clinical conditions. Laboratory and radiological findings showed signs of an acute abdomen with differential diagnosis between an infectious and an obstructive cause. Owing to the rapid and progressive toxic condition, an emergency laparoscopy was performed. An axial torsion of a swollen and gangrenous Meckel's diverticulum was detected.
