Introduction
Acute onset dyspnea with the clinical picture of pneumonia, often
associated with respiratory insufficiency, is a relatively common
clinical presentation in childhood. Most such cases are caused by an
infection of an otherwise healthy respiratory system, and usually, such
patients respond well to standard therapy with antibiotics and
corticosteroids. However, this clinical presentation can also be a
secondary complication of an underlying chronic diseases, such as
bronchial asthma, cystic fibrosis, primary ciliary dyskinesis or
immunodeficiency, some of which may represent a diagnostic conundrum.
