Pneumocystis jirovecii pneumonia

Case contributed by Dr Vikas Shah

Presentation

History of HIV, loss of viral suppression, a few weeks of shortness of breath, cough, malaise and weight loss.

Patient Data

Age: 50
Gender: Male

Chest X-ray

Modality: X-ray

Although there is no focus of airspace opacification, there is hazy ground glass attenuation change involving both lungs and a reticular pattern of opacification.

The lungs are of normal volume, there is no collapse and no pleural effusion. Further features in the history were gradual weight loss.

A whole body CT was performed to look for sources of infection and lymphadenopathy.

CT thorax

Modality: CT

A mid and lower zone diffuse ground glass pattern was seen, with admixed areas of interlobular septal thickening, giving a "crazy paving" pattern. Some small cystic spaces were observed too.

No nodules, nodes or pleural effusions were seen. The heart was not enlarged.

Case Discussion

A diagnosis of pneumocystic pneumonia (PCP) was made, the causative organism of which is pneumocystic jirovecii. This is seen almost exclusively in immunocompromised patients, particularly those with AIDS.
