Visceral larva migrans (VLM) is a clinical condition primarily associated with the migration of larvae from certain parasitic infections, most notably those caused by the Toxocara species, particularly Toxocara canis and Toxocara cati. The ICD-10-CM code for this condition is B83.0, which falls under the category of other helminthiases.

Clinical Description

Etiology

Visceral larva migrans is caused by the accidental ingestion of Toxocara eggs, which are commonly found in the feces of infected dogs and cats. Once ingested, the eggs hatch in the intestines, releasing larvae that can migrate through various tissues, including the liver, lungs, and central nervous system. This migration can lead to a range of clinical manifestations, primarily due to the host's immune response to the larvae.

Symptoms

The symptoms of visceral larva migrans can vary widely, depending on the extent of larval migration and the organs affected. Common symptoms include:

• Fever: Often a result of the immune response to the migrating larvae.
• Cough: May occur if larvae migrate to the lungs.
• Abdominal pain: Can be due to liver involvement or other abdominal organ irritation.
• Hepatomegaly: Enlargement of the liver is frequently observed in affected individuals.
• Respiratory symptoms: Such as wheezing or difficulty breathing, particularly if the larvae affect the lungs.
• Ocular symptoms: In some cases, larvae may migrate to the eyes, leading to vision problems or even blindness.

Diagnosis

Diagnosis of visceral larva migrans typically involves a combination of clinical evaluation and laboratory tests. Key diagnostic methods include:

• Serological tests: Detection of specific antibodies against Toxocara can help confirm the diagnosis.
• Imaging studies: Ultrasound or CT scans may reveal organ involvement, such as hepatomegaly or pulmonary infiltrates.
• History and exposure: A thorough history of potential exposure to contaminated soil or animal feces is crucial.

Treatment

Treatment for visceral larva migrans primarily focuses on managing symptoms and may include:

• Antiparasitic medications: Such as albendazole or mebendazole, although their effectiveness can vary.
• Corticosteroids: To reduce inflammation and immune response in severe cases.
