Lymphatic filariasis, or elephantiasis, is a serious health problem in many tropical countries. It is rare today, but it is a painful and deforming disease that is often difficult to diagnose in its early stages.

Parasitic worm infection is a common disease in the world. If there is no timely treatment, the disease will progress to severe appendicitis, peritonitis, hypoproteinemia, etc. Ultrasound is considered the most effective imaging diagnostic method to help detect parasitic worms in the early stages of the disease.
