Recurrent pneumonia and localised lung disease
Also known as Recurrent pneumonia in children · Persistent and recurrent lung consolidation · Right middle lobe syndrome · Recurrent same-site pneumonia · Localised chronic lung disease
Fellowship guide to recurrent pneumonia in children — the two-or-more-in-a-year definition, the single question that reorganises the whole work-up (same site or different sites?), the structural causes behind same-site disease, the systemic causes behind multifocal disease, and the staged investigation that turns a repeat X-ray into a diagnosis.

Red flags
- Pneumonia that recurs in the same lobe or segment is a structural lesion until proven otherwise and demands a chest CT and bronchoscopy, not a third course of antibiotics
- An unexplained persistent focal opacity in a toddler is an inhaled foreign body until excluded, even when the choking event was never witnessed and the plain film looks unremarkable
- Recurrent pneumonia at different sites points to a systemic cause — immunodeficiency, cystic fibrosis, ciliary dyskinesia, or aspiration — and needs a systematic host work-up
- A wet cough that never clears between episodes, digital clubbing, or failure to thrive signals suppurative lung disease and impending bronchiectasis
- Never accept radiographic clearing on symptoms alone — confirm resolution with a follow-up film, because a mass, malformation, or foreign body can hide behind apparent recovery
- Recurrent pneumonia with faltering growth, steatorrhoea, or a positive family history mandates a sweat test before the diagnosis is anchored elsewhere

Overview & Definition
A four-year-old arrives at clinic having had his third episode of pneumonia in eighteen months, each stamped on an X-ray, each treated with antibiotics, each apparently better by the follow-up visit. The parents want reassurance that he is simply unlucky with viruses. The job of the paediatrician is different and more demanding: to decide whether this is a normal run of childhood infection or the signal of a lung that cannot defend one part of itself, and the first step is to count the episodes honestly and look at where they landed. [3]
Recurrent pneumonia is defined by frequency, not severity. The accepted threshold is two or more episodes of pneumonia within a single year, or three or more episodes at any time, with each episode confirmed radiographically and, critically, with the chest film returning to normal between episodes. That interval clearing is what separates recurrent pneumonia from persistent or non-resolving pneumonia, where a single opacity simply never goes away. [1] [3]
The definition matters because it forces a search for an underlying cause. In the landmark case series, a clear majority of children meeting this threshold had an identifiable predisposing condition rather than bad luck, and the same finding has been reproduced across settings. Recurrent pneumonia is therefore treated as a symptom of something, and the diagnostic task is to name that something before repeated infection scars the lung. [1] [2]
