Pulmonary cryptococcosis, caused by the fungus Cryptococcus neoformans, presents varied radiographic findings. Early diagnosis is crucial, especially in immunocompromised individuals, for effective treatment of this opportunistic infection.

Area of Science:

  • Medical Mycology
  • Pulmonology
  • Infectious Diseases

Background:

  • Cryptococcus neoformans is a soil fungus.
  • It causes opportunistic infections, particularly pneumonia in immunocompromised hosts.
  • Pulmonary disease arises from inhaling the fungus.

Purpose of the Study:

  • To describe the spectrum of radiographic manifestations of pulmonary cryptococcosis.
  • To highlight diagnostic challenges and clinical considerations.
  • To emphasize the importance of considering this diagnosis in at-risk patients.

Main Methods:

  • Review of radiographic findings in patients with pulmonary cryptococcosis.
  • Correlation of imaging findings with host immune status.
  • Analysis of diagnostic difficulties.

Main Results:

  • Common radiographic findings include poorly marginated nodules or masses.
  • Lobar/segmental opacities and diffuse nodular patterns are also observed.
  • Adenopathy, effusions, and cavitation are less common, especially in immunocompetent hosts.

Conclusions:

  • Pulmonary cryptococcosis exhibits diverse radiographic presentations.
  • Diagnosis can be challenging, requiring consideration in appropriate clinical contexts.
  • Radiographic findings, particularly in immunocompromised patients, warrant further investigation for Cryptococcus neoformans.
