Pediatrics · Respiratory: primary ciliary dyskinesia

Sample item

A child has chronic wet cough, recurrent sinusitis, otitis media, and situs inversus. What diagnosis is most likely?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Primary ciliary dyskinesia

Primary ciliary dyskinesia impairs mucociliary clearance, causing recurrent sinopulmonary infection, chronic otitis, and sometimes situs inversus. Diagnosis uses specialist functional and genetic testing.

Option by option

  • A. Primary ciliary dyskinesia (correct)

    Correct. Situs inversus with chronic sinopulmonary disease is a key clue.

  • B. Cystic fibrosis

    CF can cause bronchiectasis but not typically situs inversus.

  • C. Asthma

    Asthma causes variable airway obstruction, not situs anomalies.

  • D. Bronchiolitis

    Bronchiolitis is an acute viral illness.
