CTICasesHemorrhagic pulmonary infarction
Imaging findings
Chest CT shows two small, irregularly-shaped subsegmental consolidations in the peripheral right lower lobe, which developed following an acute episode of subsegmental pulmonary embolism. The areas resolved over time to leave focal scars.
Key takeaways
Although pulmonary infarctions are classically described as wedge-shaped opacities (Hampton hump) on imaging, histopathological studies and clinical CT demonstrate they can manifest as small, irregularly-shaped consolidations that can mimic focal atelectasis or scar.
