CTICasesPneumocystis jirovecii pneumonia (PJP) with a geographic crazy paving pattern
Imaging findings
CT scan of a patient with undiagnosed HIV shows a striking geographic crazy paving pattern and ground-glass opacities, mimicking pulmonary alveolar proteinosis.
Key takeaways
PJP pneumonia classically presents with diffuse ground-glass opacities, but can manifest as a highly geographic crazy paving pattern. The presence of weight loss and lymphopenia should prompt HIV screening and PJP testing.
