CTICasesInternal Jugular Vein Varix
Imaging findings
CT in a patient with head and neck cancer shows a focal dilatation or varix of the internal jugular vein at its confluence with the subclavian vein near a valve, presenting as a heterogenous soft tissue density that mimics metastatic lymphadenopathy.
Key takeaways
Focal ectasia or a varix of the internal jugular or subclavian vein can be mistaken for pathologic lymphadenopathy on CT. Contiguity with the vessel lumen and stability on serial scans are helpful diagnostic clues.
