X-ray, Magnetic Resonance Imaging (MRI) scan, Computerized Axial Tomography scan (CAT)These tests are used to look for some parasitic diseases that may cause lesions in the organs.
Imaging exam.
Providers use imaging tests to find larval cysts. These may include CT scans, MRI scans or ultrasound.
Fecal testing (examination of your stool) can identify both helminths and protozoa. Stool samples must be collected before you take any anti-diarrhea drugs or antibiotics, or before x-rays with barium are taken. Several stool samples may be needed to find the parasite.
Once these eggs are in the bloodstream, the larvae can travel into the brain and form cysts, causing neurocysticercosis (NCC). Symptoms of NCC can include seizures, headaches, or dizziness, although some patients with NCC show no symptoms.
Parasitic diseases are diagnosed and treated every day in the United States. Some are common and some are very rare, found only in travelers or immigrants from areas where the parasites are common. Diagnosis is sometimes difficult and may require a specialist.
Many people mistakenly attribute their symptoms to some other disease and don't even think to ask for a parasites test. Another reason for the under-diagnosis of parasites is that doctors nowadays aren't well trained in detecting these critters.
Your conventional medicine doctor can run an O&P fecal test, which will microscopically detect if ova or parasites are present in your stool. A more specific way to test for parasites is through a comprehensive stool analysis that looks for specific parasites and other pathogens.
The infection is treated with albendazole or praziquantel (drugs used to treat parasitic worm infections, called antihelminthic drugs). However, if a person has many cysts, antihelminthic drugs may kill many organisms, causing the brain to swell significantly.

headache – which is often severe, located in a single section of the head and cannot be relieved with painkillers. changes in mental state – such as confusion or irritability. problems with nerve function – such as muscle weakness, slurred speech or paralysis on one side of the body. a high temperature.
Here are some common signs of parasites to look out for: Gastrointestinal issues like bloating, gas, constipation, diarrhea, nausea, and vomiting (especially common with Blastocystis infections) Problems with your skin such as rashes, itchiness, hives, or eczema. Feeling anxious and not being able to explain why.
Parasites could be using glucose (or other things present in the host blood after eating) as a food source: When hosts eat, parasites eat.
Helminths can be recognized in ultrasound images by their morphology, size, and location. In some cases, the parasites are not directly seen by ultrasound, but the lesions caused by them can be easily visualized. Ultrasound imaging is taking on an increasingly important role in veterinary parasitology.
For serious cases, your doctor may use imaging tests such as computed tomography (CT) or magnetic resonance imaging (MRI) to check for tapeworm lesions or secondary swelling outside of the digestive tract. The type and length of treatment may depend on the type of tapeworm you have.
Redness, pain, and swelling occur at the sites of the stings. The stings look like flat red lesions (macules) and solid raised bumps (papules), some of which may contain pus (pustules).
In populations living in adverse conditions due to poverty, a wide variety of intestinal parasite infections can be observed. These infections are usually diagnosed by stool microscopy, but can be easily missed if the procedures used are inaccurate or performed in a suboptimal way.
Giardia is arguably the most common parasite infection of humans worldwide, and the second most common in the United States after pin-worm.
Your health care provider may order tests if you or your child has symptoms of an intestinal parasite. These include: Diarrhea that lasts for more than a few days. Abdominal pain.
Naegleria fowleri infections are rare.* In the United States, between zero and five cases were diagnosed annually from 2013 to 2022.
The Spirometra tapeworm can live in humans for up to 20 years.
Albendazole and mebendazole are most frequently prescribed for treatment of intestinal nematode infections (ascariasis, hookworm infections, trichuriasis, strongyloidiasis, and enterobiasis) and can also be used for intestinal tapeworm infections (taeniases and hymenolepiasis).
Blood tests such as an eosinophil level -- a type of blood cell that is increased in many parasitic diseases -- can be helpful, and occasionally stool tests are of benefit. A few people need skin scrapings or even biopsy of skin lesions that can be evaluated by a laboratory to determine whether a parasite is present.
Some drugs (antiparasitic drugs) are designed particularly to eliminate parasites or, in the case of some worm infections, reduce the number of worms enough so that symptoms clear up. Also, certain antibiotics and antifungal drugs are effective against some parasitic infections.
Some parasites go away on their own, especially if you have a healthy immune system and maintain a balanced diet. However, talk to a healthcare provider if you have signs of a parasitic infection. They can make an official diagnosis and help prevent the spread of the parasite to others.
