From: Endocavitary contrast enhanced ultrasound (CEUS): a novel problem solving technique
Contrast ultrasound agent administered through a “port-a-cath” for a malfunctioning line causing point tenderness. (A) CEUS and corresponding greyscale image. The subcutaneous course of the line is seen (thick arrow) and luminal patency is confirmed on the contrast image. (B) At the point of tenderness there is contrast extravasation deep to the line where there is a small fluid collection on greyscale imaging (thin arrow). (C) Conventional fluoroscopic linogram, minor irregularity is present along the midportion of the line confirming the site of line rupture (arrow)
