CTICasesMetastatic mucinous colon adenocarcinoma with tumor emboli and pulmonary infarction
Imaging findings
CT scan shows calcified mediastinal and abdominal lymphadenopathy, extensive nodular and lymphangitic pulmonary metastases, and severe narrowing of the right upper lobe vessels from tumor emboli, leading to wedge-shaped pulmonary hemorrhage and infarction.
Key takeaways
Mucinous adenocarcinomas (such as colon cancer) can cause calcified lymph node metastases. Tumor emboli and endovascular tumor growth can cause severe arterial occlusion, leading to pulmonary ischemia or infarction.
