59-year-old male with central venous catheter, question of clot or thrombus at catheter site. Grayscale and color ultrasound of the right neck soft tissues surrounding the central venous catheter demonstrates trace adjacent fluid, but no discrete fluid collection or other significant abnormality surrounding the catheter along its subcutaneous course.
No significant soft tissue abnormalities or collections surrounding the catheter. If there is continued concern for catheter thrombosis, the catheter may be interrogated by interventional radiology as warranted clinically.
