Infant status post PICC placement 1 month ago with an incidental calcification on their AXR

CXR and US of inferior vena cava thrombus caused by peripherally inserted central catheter / PICC
AXR AP shows the tip of a lower extremity PICC projecting within the inferior vena cava with its tip at T11 with a long tubular calcification extending from the PICC tip to the level of the right atrium. Transverse US of the liver at the level of the hepatic veins draining into the inferior vena cava shows a round echogenic lesion with posterior shadowing within the inferior vena cava that extended from the tip of the PICC to the cavo-atrial junction.

The diagnosis was chronic thrombus of the inferior vena cava secondary to PICC placement.
