Echinococcal cyst is also known as which term?

• A. Hydatid disease
• B. Cystic echinococcosis
• C. Amebic liver abscess
• D. Biliary obstruction

Answer: (A)

Echinococcal cysts are traditionally described as hydatid cysts, reflecting the parasite that forms them. The disease caused by Echinococcus, including these cysts, is commonly termed hydatid disease. Because the question asks for the term used for the echinococcal cyst, hydatid disease is the most fitting label, since it directly names the infection’s cystic manifestation. The other options point to entirely different conditions—an amebic liver abscess from Entamoeba histolytica or biliary obstruction due to other causes—so they don’t describe the echinococcal cyst. In practice, cystic echinococcosis is the formal disease term, but the cyst itself is described as a hydatid cyst, and the broader disease label hydatid disease is the widely used shorthand.
