CTICasesChronic Thromboembolic Disease with Hilar Mass
Imaging findings
Dilated right heart chambers and pulmonary arteries with organizing thrombus layering the arterial walls. Biopsy showed organizing fibrin thrombus, initially mimicking neoplasm.
Key takeaways
Organizing thrombus in chronic thromboembolic pulmonary hypertension can sometimes mimic a firm, hilar mass on imaging, necessitating careful tissue correlation.
