Pathology and Clinical Features of Echinococcosis

Echinococcosis includes cystic echinococcosis (CE) and alvealar echinococcosis (AE), and the clinical and pathological features are completely different. The diagnostic techniques of two types of echinococcosis mainly include serological detection and imaging detection. AE is invasive and metastasis to other organs, such as lung, brain, and bone. The clinical presentation includes abdominal pain, jaundice, and portal hypertension. The prognosis of patients without treatment is poor. Germinal cells are contained in the cyst wall of CE, which is the main site of parasite development. CE grows continuously and causes mechanical compression for surrounding tissues. Cyst fluid of CE can cause allergic reactions, and some cysts are associated with bile leakage. The prognosis of CE is better than AE.
