An unexpected cause of pleural effusion in paediatric emergency medicine.

Pancreaticopleural fistula (PPF) is an uncommon complication of chronic pancreatitis leading to a large and recurrent pleural effusion. Since the patients presented predominantly with respiratory symptoms, diagnosis and treatment were often delayed. We describe a child who was admitted to our paediatric emergency department with an acute onset of dyspnoea and unilateral massive pleural effusion caused by PPF. Multidetector CT is an easily accessible method that is able to show both the thoracic and abdominal findings non-invasively. The clinical and imaging features of this unusual entity are discussed.
