Chronic invasive fungal sinusitis

Chronic invasive fungal sinusitis is a form of invasive fungal sinusitis

The condition has a more prolonged course than acute invasive fungal sinusitis, usually more than 12 weeks 5. Patients are usually immunocompetent or have a milder level of immunocompromise. There may be a history of chronic sinusitis.

CT usually shows homogeneous opacification (iso- to hyperattenuating to muscle tissue) of the affected sinus(es).

Other suggestive features include:

  • relative lack of expansion of sinuses 2
  • mottled lucencies or irregular bone destruction may be seen
  • bone erosion being localised to the area of extra-sinus extension 2
  • extra-sinus component of the disease being more than the intra-sinus component 2
  • there may also be sclerotic changes in the bony walls of the affected sinuses representing chronicity of disease 3

Signal characteristics of affected region include:

  • T1: iso- or hypointense signal
  • T2: usually markedly hypointense signal
