Alveolar echinococcosis
Alveolar Echinococcosis (pronunciation: al-vee-uh-lar eh-kih-no-kok-sis) is a rare but serious parasitic disease caused by the larval stage of the Echinococcus multilocularis tapeworm.
Etymology
The term "Alveolar" is derived from the Latin word "alveolus" meaning small cavity, referring to the honeycomb-like appearance of the parasite's cysts in the liver. "Echinococcosis" comes from the Greek words "echinos" meaning hedgehog and "kokkos" meaning berry, referring to the spiny appearance of the adult tapeworm.
Overview
Alveolar Echinococcosis primarily affects the liver, but can spread to other organs of the body. It is characterized by the slow growth of multiple parasitic cysts that resemble a malignant tumor. The disease is often mistaken for liver cancer or cirrhosis due to its similar symptoms and imaging characteristics.
Transmission
The disease is transmitted through the ingestion of Echinococcus multilocularis eggs, which are often spread through the feces of infected foxes, dogs, or cats. Humans can become infected by accidentally ingesting the eggs from contaminated food, water, or soil.
Symptoms
Symptoms of Alveolar Echinococcosis may include abdominal pain, weight loss, and jaundice. However, many people with the disease do not show symptoms until the disease has progressed significantly.
Diagnosis and Treatment
Diagnosis is typically made through imaging tests such as ultrasound, CT scan, or MRI, and confirmed through serology tests. Treatment usually involves a combination of surgery and long-term antiparasitic therapy.
