What is periportal cuff on ultrasound

Is it possible to see worms on ultrasound, are they visible, will it show whether it determines helminths?

Helminthiases are a variety of diseases caused by worms (helminths) of various types. The development of helminthias goes through two phases - acute and chronic, the time of its development depends on the type of worms.

In the acute phase of the disease, parasites are introduced into the body and begin to multiply, usually this is manifested by non-specific body reactions that depend on the type of worms, but there are common signs. It is a fever, a rash like allergic urticaria, swelling of the face, constipation or diarrhea, loss of appetite, tiredness, paleness, drowsiness.

When a process turns into a chronic form, the disease manifests itself as a violation of the work of various organs and systems, these manifestations depend on where the worms are, their quantities and toxins that they excrete. Most commonly affected are the gastrointestinal tract, lungs, muscles, brain, and immune system.

Worm detection methods using ultrasound

There are many methods of detecting parasites in the body. To discover worms and their eggs, the analysis of feces for eggs from helminths is most often carried out. Urine, bile, and blood are tested less frequently. However, this doesn't always help identify parasites that are outside of the intestines. In some situations, special surveying methods are used that can identify the location and type of worms. These are ELISA (enzyme immunoassay), RA (agglutination reaction), radiography, CT. Certain types of worms can be seen on ultrasound, and also indirect signs suggest their presence and localization in the human body.

The advantage of ultrasound is that it is safe for humans. The study is often repeated without the risk of complications.

Most often, on the ultrasound, you can see the indirect symptoms of the presence of worms in the body. Therefore, if a person has already been diagnosed with helminthiasis, the study will help pinpoint the site of parasite localization, as well as organ damage due to the presence of parasites in it. If ultrasound imaging detects organ damage but there is no clear reason for the changes, it can lead the doctor to consider helminthiasis and do appropriate tests to confirm the diagnosis and treatment.

Pancreatic ultrasound in patients with helminthiasis will show an increase in the size and densification of an uneven organ.

Ultrasound of the liver with helminthias shows an increase in size indicating inflammation of the liver (hepatitis) caused by worms.

With opisthorchiasis on ultrasound, it is possible to see such indirect signs of worms as a violation of the patency of the biliary tract, enlargement of the liver ducts and the common bile duct, impaired mobility and contractility of the gallbladder.

With echinococcosis on ultrasound, you can see cysts - round formations with clear contours. It can be either one cyst or several. If the course of this helminthiasis is chronic, the study shows calcified (dense) cysts. If the cyst is pus, its outlines will not look clear. There are also possible repeated manifestations of echinococcosis after surgery, then ultrasound determines worms in the liver. In so-called multi-chamber echinococcosis, the ultrasound of the liver shows single or multiple round formations of irregular structure, irregular shape with indistinct edges, dense and enlarged liver. In the middle of such formations there is a cavity with "torn" edges and dense contents. With alveococcosis on the ultrasound of the liver, small nodes up to 1-2 cm can be seen

It should be remembered that completion of the investigation should only be considered in conjunction with the remaining specific analyzes. Regardless, this method cannot confirm the diagnosis of helminthiosis.
