Imaging findings
A non-contrast CT revealed multiple hyperdense areas within the pulmonary arteries, with associated right heart enlargement. An arterial study confirmed these to be pulmonary emboli.
Key takeaways
Massive pulmonary emboli can occur in individuals who are severely dehydrated, such as marathon runners, and may present with hyperdense thrombus on non-contrast CT due to desiccation or other factors. Prompt diagnosis and treatment, such as embolectomy, can lead to good outcomes.
