Kartagener syndrome

Kartagener syndrome is a subset of primary ciliary dyskinesia, an autosomal recessive condition characterised by an abnormal ciliary structure or function, leading to impaired mucociliary clearance. 

The prevalence of primary ciliary dyskinesia is approximately 1 in 12,000-60,000 5. Approximately 50% of patient with primary ciliary dyskinesia have Kartagener syndrome/situs abnormality. No gender predilection is recognised. 

Kartagener syndrome is characterised by the clinical triad of 1:

Other features include:

  • telecanthus: widened interpupillary distance by a nasal polyp 
  • infertility in males
  • subfertility in females
Plain radiograph

Chest radiographic findings depend on the severity of underlying bronchiectasis. Findings may include bronchial wall thickening, bronchial dilatation with the loss of normal peripheral tapering:

  • predilection to involve the right middle, lingular segment of the left upper lobe and the lower lobes
  • mucus plugs may be visible, finger in glove sign
  • consolidation
  • situs abnormality, i.e. situs inversus
CT

CT tends to demonstrate bronchiectasis which may be variable in severity. However, changes are much milder than in cystic fibrosis 4. The morphology of bronchiectasis can be tubular/cylindrical or saccular/cystic. Also, CT demonstrates:

Situs abnormality with associated lower lobe bronchiectasis should prompt the diagnosis of Kartagener syndrome. However, there is a differential:

Manes Kartagener was a Zurich pulmonologist who first reported the clinical triad of sinusitis, bronchiectasis, and situs inversus in 1933 3. It was not until the 1970s, Bjorn Afzelius, an ultrastructuralist, noted the associated infertility in males. Afzelius noted the diversity of structural defects which can affect the dynein arms and/or radial spokes of the sperm tail 3. Further work was undertaken by Jennifer Sturgess, an ultrastructuralist from Toronto who identified the radial spoke defect as a common feature of Kartageners syndrome and immotile cilia syndrome. She also contributed to research in cystic fibrosis which shares clinical similarity to primary ciliary dyskinesia.
