What is Cysticercosis?

Cysticercosis is a tissue infection caused by the young form (larvae) of the pork tapeworm, Taenia solium [3][1]. This parasitic infection occurs when an individual ingests tapeworm eggs, which can be found in contaminated food or water [5][12].

Life Cycle and Transmission

The life cycle of T. solium is maintained through the ingestion of infected pork or contaminated food and water [9]. The larvae (cysticerci) develop within the intermediate host, which can be humans, pigs, or other animals [1]. Cysticercosis spreads through the feces of an individual infected with the adult tapeworm T. solium [12].

Symptoms and Complications

The incubation period prior to the appearance of clinical symptoms is variable, and infected people may remain asymptomatic for many years [2]. In some endemic regions, infected individuals may develop visible or palpable subcutaneous nodules [2]. Neurocysticercosis, a serious complication resulting from infection of the brain parenchyma, can cause seizures, hydrocephalus, encephalopathy, and meningoencephalitis [11].

Symptoms

Cysts in the nervous system can cause symptoms such as seizures, headache, dizziness, nausea, vomiting, altered mental status, altered vision, and other neurological manifestations [4]. The description of a heavy infection varies but generally includes the detection of cysts at two of the predilection sites plus two sites in the legs [8].

Prevention

Preventing cysticercosis involves avoiding the ingestion of contaminated food or water. Proper cooking and handling of pork can also help prevent the transmission of this parasitic infection.

Symptoms of Cysticercosis

Cysticercosis, an infection caused by the larvae (young worms) of tapeworms, can manifest in various ways depending on the location and number of cysts in the body. The symptoms can occur months to years after infection, usually when the cysts start dying.

Common Symptoms:

• Seizures [6]
• Headache [6]
• Dizziness [6]
• Nausea [6]
• Vomiting [6]
• Altered mental status [6]
• Altered vision [6]
• Focal neurological deficits (16%) [7]
• Increased intracranial pressure (12%) [7]
• Cognitive decline (5%) [7]
• Seizure [14]
• Upset stomach, or feeling like you could throw up. [9]
• Stomachache or stomach pain. [9]
• Not wanting to eat. [9]
• Loose stools. [9]
• Diarrhea. [9]
• Weight loss. [9]

Other Manifestations:

• Meningoencephalitis
• Psychiatric disorder
• Stroke
• Radiculopathy

Symptoms Depending on Location:

• Cysts in the brain, eyes, heart, muscle tissue, or liver can cause a range of symptoms.

It's essential to note that many individuals with cysticercosis may never experience any symptoms at all [13]. If you think you have cysticercosis, it is crucial to consult your healthcare provider for proper diagnosis and treatment.

Based on the context, here are some diagnostic tests for cysticercosis:

1. Imaging studies: Contrast-enhanced CT scanning or MRI is the mainstay of diagnosis.
2. Serological testing:
   • Enzyme-linked immunoelectrotransfer blot (EITB)
   • Commercial enzyme-linked immunoassays
3. Lumbar puncture
4. Biopsy
5. Eye exam: To detect cysticerci in the eye
6. Blood tests: To detect antibodies to T. solium (cysticercosis serology test)
7. PCR-based diagnostics: In development, including antigen assays and PCR-based diagnostics

Please note that a combined testing approach is recommended to confirm infection and inform treatment strategy.

Treatment Options for Cysticercosis

Cysticercosis, an illness caused by ingesting the eggs of the parasite T. solium, can be treated with various medications. The treatment approach varies depending on the severity and location of the infection.

• Antiparasitic Drugs: Praziquantel and albendazole are commonly used antiparasitic drugs to treat cysticercosis. These medications have been shown to be effective in reducing the number of cysts in the body [5][6].
• Combination Therapy: A combination of praziquantel and albendazole has been recommended for the treatment of neurocysticercosis (NCC) [7]. This combination therapy has been found to be more effective than using either medication

Differential Diagnosis of Cysticercosis

Cysticercosis, caused by the larval stage of Taenia solium, can be challenging to diagnose due to its similarity with other neurological conditions. A differential diagnosis is essential to rule out other possible causes of symptoms.

Possible Differential Diagnoses:

• Cerebral Metastasis: This condition involves the spread of cancer cells to the brain and can present with similar symptoms to cysticercosis, such as seizures and headaches.
• Brain Tumors: Various types of brain tumors, including gliomas and meningiomas, can cause neurological symptoms that may be mistaken for cysticercosis.
• Infections: Other infections, like toxoplasmosis or cryptococcosis, can also present with similar symptoms to cysticercosis.

Diagnostic Tools:

To differentiate cysticercosis from other conditions, various diagnostic tools are used:

• Imaging Studies: CT and MRI scans can help identify the presence of cysts in the brain, which is a hallmark of cysticercosis.
• Serological Tests: Blood tests can detect antibodies against Taenia solium, providing evidence of infection.
• Biopsy: In some cases, a biopsy may be performed to confirm the diagnosis.
