It is a cyst formed in the liver or, less frequently, elsewhere, that contains larvae of the tapeworm Echinococcus granulosus, chiefly in ruminants, whose eggs are carried from the intestinal tract to the liver through the blood.
An anal fissure is a cut or tear occurring in the anus (the opening through which stool passes out of the body) that extends upwards into the anal canal. Patients may try to avoid defecation because of the pain. The pain may also affect urination causing dysuria, frequent urination, or the inability to urinate. Bleeding in small amounts, itching (pruritus ani), and a malodorous discharge may occur due to the discharge of pus from the fissure.
