CTICasesIntravascular hydatid disease with pulmonary embolism
Imaging findings
CT angiogram shows large, lobulated intravascular filling defects expanding the main and right pulmonary arteries, accompanied by conglomerate mediastinal lymphadenopathy and multiple cystic, calcified liver lesions.
Key takeaways
Echinococcus granulosus (hydatid disease) can rupture from hepatic cysts into the inferior vena cava, leading to intravascular embolization into the pulmonary arteries. This rare manifestation can mimic thromboembolic disease or sarcoma.
