alveolar hydatid disease

alveolar hydatid disease
a type of hydatid disease in which larval forms (hydatid cysts) of Echinococcus multilocularis invade and destroy tissues, undergoing endogenous budding to form an aggregate of small cysts that honeycomb the affected organ (usually the liver); in time the cysts may metastasize to other organs.
