KROK 1 2014 – Question 143 · KROK (Medicine) · Pathomorphology
An HIV-positive patient’s cause of death is acute pulmonary insufficiency resulting from pneumonia. Pathohistological investigation of lungs has revealed interstitial pneumonia, alveolocyte desquamation and their metamorphoses: alveolocyte enlargement, large intranuclear inclusions surrounded by lightly colored areas. Transformed cells resemble owl’s eye. Name the pneumonia causative agent:
- A. Cytomegalovirus
- B. Influenza virus
- C. Pneumococcus
- D. Candida fungi
- E. Toxoplasma
Hint
Intranuclear inclusions with a halo and cell enlargement are cytopathic changes; decide which class of opportunistic pathogen in advanced HIV infection produces them.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
