CTICasesMetastatic Paraganglioma Mimicking DIPNECH
Imaging findings
CT chest shows multiple hypervascular pulmonary nodules and mosaic air trapping, in a patient with a primary paraganglioma of the organ of Zuckerkandl and metastatic disease to the liver, confirmed on MIBG scan.
Key takeaways
Metastatic neuroendocrine tumors, such as paraganglioma, can present with multiple pulmonary metastases. Interestingly, the hypervascular metastases and associated airway narrowing or vascular shunting can produce a mosaic pattern on CT that radiographically mimics DIPNECH.
