- Fig 1-4. Axial inspiratory images. Extensive, bilateral perihilar ground-glass opacities and relative peripheral sparing.
- Fig 5,6. Coronal inspiratory images. Extensive, bilateral perihilar ground-glass opacities and relative peripheral sparing.
Diagnosis:
Pneumocystis jiroveci pneumonia
Discussion:
- Pneumocystis jiroveci pneumonia is common opportunistic infection in immunocompromised patients such as HIV positive.
- Imaging Findings on HRCT Chest:
- Bilateral extensive ground glass opacities with upper lobe predilection. Ground glass opacities may be central with relative peripheral sparing or diffuse with mosaic pattern.
- With advanced disease, crazy paving or consolidation may develop.
- Pulmonary cysts of variable size, shape and wall thickness may be present. Nodules may be present.
- Cysts are associated with spontaneous pneumothorax.
- Cysts resolve with resolution of infection.
