CTICasesLipiodol embolization after lymphangiography
Imaging findings
CT scan performed shortly after a lymphangiogram with Lipiodol shows contrast lining the pelvic lymphatics, cisterna chyli, and thoracic duct. There is also dependent contrast consolidation at the lung bases representing oil embolization in the pulmonary capillaries.
Key takeaways
Lipiodol, an oil-based contrast agent used in lymphangiography, can embolize to the pulmonary capillaries, causing transient dependent consolidation and chemical pneumonitis.
