Ultrasound artifact

Case contributed by Dr Daniel J Bell

Presentation

Incidental finding. Pain post laparoscopic salpingectomy.

Patient Data

Age: 30 years
Gender: Female
Ultrasound

Small focal echogenicity superficially in the middle of the image, passing a short distance posteriorly into the dermis and just into the most superficial subdermal fat. This abnormality was seen on all images using this linear transducer but not using a different transducer.

Physical inspection of the transducer demonstrated a defect in the lens of the ultrasound transducer representing physical damage to the probe. This probe was therefore withdrawn from service to be sent back to the manufacturer for repair.

Case Discussion

Artifacts on ultrasound images may result from the hardware itself. In this case there is damage to the acoustic lens of the transducer. This results in signal drop out or other abnormalities on the images.

This damage is usually due to the operator dropping the transducer onto the floor or it may be due to inappropriate cleaning techniques of the transducer.
