Elephantiasis is a complication most commonly associated with which condition?

• A. Cysticercosis
• B. Guinea worm infection
• C. Hydatid cyst disease
• D. Filariasis

Answer: (D)

Elephantiasis reflects involvement of the lymphatic system by a lymphatic filarial infection. The adult worms live in lymph vessels and trigger inflammation and blockage, which disrupts normal lymph drainage. Over time this causes chronic swelling and thickening of the skin, most often in the limbs and genitals—classic signs of lymphatic filariasis. The other conditions don’t primarily cause this pattern. Cysticercosis results from tapeworm larvae and often affects the brain or eyes rather than the lymphatic system. Guinea worm infection produces painful skin ulcers as the worm emerges but is not defined by lymphatic obstruction leading to extreme limb swelling. Hydatid cyst disease forms cysts in organs like the liver or lungs due to Echinococcus, not by blocking lymphatics. So the association of elephantiasis most strongly points to filariasis.
