From: Procedural complications of inferior vena cava filter retrieval, an illustrated review
This patient had a suprarenal Günther Tulip IVC filter (Cook, Bloomington, IN) placed at OSH approximately 5 years prior to obtaining this CT. Images showed the filter hook outside the lumen of the IVC and within hepatic parenchemya and possibly into the portal vein. Given that the patient was asymptomatic and that filter removal could lead to signfiicant complications it was elected not to pursue retrieval
